The Winter Performance of Glass Insulators: What You Need to Know

December 8, 2025

Winter can stress the strength and integrity of each component in an electrical system, especially insulators. Glass insulators are a preference because of their unique characteristics, but how do they perform in extreme winter conditions? Below are responses to common questions about the strength and efficiency of glass insulators in winter.

What Makes Glass Insulators Strong in Winter?

Glass insulators are designed to operate under severe environmental conditions, such as ice, snow, and frozen rain. Their smooth surface is resistant to ice formation, and thus, they remain capable of performing their insulation function even at sub-freezing temperatures. That is why they are most suitable for high-voltage transmission lines and other safety-critical electrical applications.

Do Glass Insulators Prevent Short Circuits During Winter Storms?

Glass insulators perform exceptionally well in suppressing short circuits under challenging conditions. Blizzards can drop contaminants such as salt, factory dust, or particulates, or chemicals onto electric systems that act as conductivity pathways for electricity, causing faults. Glass insulators are a superior technology for shedding these contaminants away from electrical faults.

Are Glass Insulators able to resist Large Ice or Wind Loads?

Yes, glass insulators are made with superior mechanical strength, allowing them to withstand the weight of power cables when subjected to added stress due to heavy ice or strong winds. Their durability enables them to withstand mechanical loads without breaking, even under severe winter weather conditions.

How Do Glass Insulators Compare to Polymer or Porcelain during Winter?

Polymer insulators are lightweight, while porcelain insulators are known for their long-lasting properties. Glass insulators, on the other hand, offer special advantages in terms of mechanical strength, dielectric properties, and longevity. Glass insulators resist surface degradation over time and are therefore more suitable in environments with high contamination or rigorous winter conditions. Furthermore, semi-conducted glaze glass insulators are specially designed for improved performance in salt spray, crop dust, or industrial pollution conditions common in the winter season.

Do Glass Insulators Have a Long Service Life?

Glass insulators are extremely durable. They retain their mechanical and electrical performance for decades, even under the harshest environmental conditions. It is this durability that makes them an economic solution for power systems that need constant maintenance throughout the year.

Why Are Glass Insulators Suitable for High Voltage Systems During Winter?

Glass insulators have greater dielectric strength, or the ability to withstand high voltage without allowing electricity to flow through any route other than the intended one. It is crucial during winter when power demand is higher and lines are put under greater stress. Being capable of continuous service under high voltage translates to uninterrupted service.

Where Are Glass Insulators Used During Winter?

Glass insulators have better dielectric strength, meaning they can carry high voltages without allowing electricity to flow in undesired paths. This is particularly necessary in winter, when the electrical load is higher and the power transmission lines are under more stress. Their efficiency at high voltage facilitates the smooth supply of service. Their flexibility and reliability make them a first selection for mission-critical applications.

Durability and Reliability: How Semi-Conductive Glaze Insulators Thrive in Freezing Temperatures

November 3, 2025

Insulator reliability and lifespan are critical for high-voltage power systems in freezing weather conditions. Semi-conductive glaze Insulators are designed to meet extreme cold climate conditions with ice, ensuring effective performance and long-term stability even under adverse weather conditions. They have proven themselves worthy for over 50 years of service in industry and utility environments where freezing conditions and contamination exist as actual realities. So, what distinguishes Semi-Conductive Glaze Insulators as especially valuable under these circumstances? Let’s find out the topmost reasons.

Resilience Against Ice Accretion

Under cold temperatures, ice quickly forms on insulators, leading to ice accretion. This impairs their operation by creating a water film, which enhances electric stress. However, Semi-Conductive Glaze Insulators have overcome this issue. Dopants like Tin and Antimony transform the unique glaze into a semi-conductive surface that inhibits static charges from accumulating. Thus, ice formation and electric stress is reduced. Field testing at sub-freezing temperatures showed that semi-conductive glaze insulators consistently outperformed the performance of standard insulating glaze and silicone-coated insulators.

Designed for Contaminated Environments

Colder climates generally accompany other environmental issues, such as sea salt contamination, industrial facilities, or even agricultural practices. Semi-conductive glaze insulators have been designed to endure all these polluted environments. These insulators demonstrate maximum performance when exposed to salt spray, industrial fog, or urban pollution. Pollution tests following IEC 60507 standards demonstrated that Newell’s Semi-Conductive Glaze units are resistant to salinity; this, in turn, reduces the probability of failure through contamination and ice formation.

Proven Field Experience and Standards Compliance

Semi-conductive glaze insulators have been employed in the industry for over 50 years with a near-error-free record of field performance. They are superior or equal to the ANSI, IEC, and IEEE standards, guaranteeing that they are extensively tested for harsh environments. Each unit is extensively tested to ensure leakage current levels and resistive performance to ensure that it can withstand the highest degree of pollution and ice accretion.

Short Lead Times and Ready-to-Ship Inventory

At Newell, one of our greatest advantages over our competitors is that we can stock and ship insulators quickly, with short lead times.

The Backbone of Substations: Understanding Station Post Insulators

October 20, 2025

When you think of the critical components of an electrical substation, transformers, circuit breakers, and switches might come to mind. However, one key element often overlooked is the station post insulator. These unsung heroes ensure the safety and reliability of the entire system by insulating high-voltage components and supporting mechanical loads. In this blog post, we’ll dive into the importance of station post insulators, explore the various types available, and discuss how they’re tailored for different operational conditions in industrial and utility applications.

What Are Station Post Insulators?

Station post insulators are essential components used to mechanically support and electrically isolate other equipment in substations. Typically made of porcelain and covered with a protective glaze, these insulators are designed to withstand high voltages while preventing electrical currents from flowing to unwanted parts of the substation. Their primary function is to maintain the structural integrity and safety of the substation, even under severe stress or environmental conditions. The glaze used on these insulators also resists the accumulation of contaminants, allowing for easy cleaning through rain or artificial methods.

How Station Post Insulators Ensure Substation Safety and Efficiency

One of the primary roles of station post insulators is to prevent electrical currents from short-circuiting or grounding in areas where they shouldn’t. Substations are complex environments with numerous high-voltage components. Electrical currents could flow along unintended paths without proper insulation, causing system malfunctions, potential hazards, or equipment failures. The insulators keep everything running smoothly, ensuring electrical systems operate efficiently and safely.

Station post insulators must endure mechanical stress in addition to electrical isolation. They support the weight of electrical components while withstanding environmental factors such as wind, earthquakes, and temperature fluctuations. This dual functionality makes them indispensable in any substation setup.

Different Types of Station Post Insulators and Their Applications

Several types of station post insulators are suited for specific substation needs. Here’s a breakdown of the most common types:

  1. Non-Stacking Units: These are single-piece insulators that don’t require stacking, making them ideal for lower-voltage applications. Their typical sizes range from TR202 to TR295. They are often used in smaller substations where voltage requirements are lower and complex support structures are less needed.
  2. Uniform Diameter Stacks: Uniform diameter stacks are commonly used for higher voltage applications. These insulators have a consistent diameter throughout their length and are stacked to achieve the required insulation level. Sizes for these insulators typically range from TR304 and above. They’re perfect for larger substations where high-voltage insulation is crucial.
  3. Tapered Stacks: Tapered stack insulators save weight and cost while still providing adequate insulation. These stacks comprise posts with varying diameters, offering identical electrical and cantilever ratings as their uniform diameter counterparts but lower tension and torsion ratings. This makes them an economical option without compromising performance in many applications.
  4. Cap-Pin Replacement: Traditional cap-and-pin insulators have design flaws that make them more susceptible to failure than modern station post insulators. As a result, cap-pin replacement units are often used to retrofit older substations with more reliable station posts. This helps improve overall system reliability and reduces the risk of outages.
  5. High-Leak Units: In polluted environments, such as industrial areas or coastal regions, insulators are exposed to contaminants like salt spray or chemical particles. High-leakage station post insulators have extended leakage distances achieved through more or larger shed profiles, improving performance and reducing the likelihood of flashovers in these harsh environments.

Tailoring Station Post Insulators to Operational Conditions

Not all substations are the same, and neither are their insulation needs. Depending on the environment, station post insulators are tailored to meet specific electrical and mechanical requirements. For instance, high-leak units with larger shed profiles are used in areas prone to pollution. In coastal regions, insulators with semi-conducting glaze may be necessary to resist the effects of salt spray and airborne particles. These premium insulators are designed for use in contaminated environments, making them invaluable in specific locations.

Additionally, insulators’ strength, material composition, and shed design can be customized to meet the demands of different operational conditions. This ensures that whether a substation is located in an industrial zone, rural farmland, or near the coast, there is an insulator that fits the bill.

Choosing the Right Insulator for Your Needs

Understanding the role of station post insulators in a substation’s operation is crucial to maintaining safety and efficiency. Whether you’re looking for a non-stacking unit for a low-voltage application or a high-leak unit for a coastal substation, Newell’s wide range of insulators is stocked and ready to ship, minimizing lead times and ensuring your projects stay on track. As a trusted provider of high-quality insulators, Newell offers tailored solutions to meet the most demanding electrical and mechanical requirements.

These advanced solutions are helping to support and strengthen the next generation of offshore wind infrastructure.

How High-Voltage Insulators Ensure Reliable Power Transmission from Offshore Wind Farms

September 4, 2025

Wind-powered offshore electricity is becoming an essential source of renewable energy for millions of homes. However, transmitting this energy to the onshore grid presents a unique set of challenges due to the harsh marine environment. To overcome these hurdles, high-voltage insulators, specifically engineered for offshore conditions, play a critical role in ensuring reliable and uninterrupted energy transmission. These advanced solutions are helping to support and strengthen the next generation of offshore wind infrastructure.

Tackling Contaminated Environments with Advanced Materials

Adverse to the marine environment, power transmission equipment must contend with the internal limitations of salt fogs and sea mist, which can conduct high currents and lead to short-circuiting in normal insulators. Semi-conductive glaze insulators by Newell are specifically designed for such an environment. With the use of advanced dopants like those of tin and antimony, the glaze converts itself from an insulating to a semi-conductive property, thereby minimizing leakage currents of any kind and performing with operational stability. These insulators meet artificial pollution tests as defined by IEC and perform better than conventional insulators at salinities up to 224 kg/m³. High-voltage insulators protect against clean contamination failure for faultless operation at offshore wind farms.

Solid Core Construction to Counteract Adverse Weather

Harsh weather conditions, such as icing, snow bridging, or gusts, are the usual conditions offshore. Insulation material, therefore, used in such weather conditions needs to have superiority in resilience. All this has led to cutting-edge technology where Newell’s solid core construction eliminates all the limitations of hollow-core designs and offers unparalleled mechanical strength and reliability.

Built with durability in mind, these insulators are engineered to endure substantial mechanical stress while withstanding the corrosive effects of the offshore environment. This resilience translates to fewer maintenance demands and less unplanned downtime—key advantages for operators managing remote wind installations.

Enhanced Performance in High-Voltage Applications

High voltage transmission requires insulators that are capable of withstanding gargantuan electrical stresses without a compromise to either the safety or the efficiency of operations conducted. Newell insulators are tested to meet even the most demanding standards of ANSI, IEC, and IEEE specifications. Accordingly, for instance, semiconductive glaze systems undergo 100 percent leakage current testing, thereby ensuring ultimate performance when used at high voltages.

Maintaining the necessary level of capacitance and reducing resistive leakage enables efficient energy transfer occurring from the turbines to the onshore grid, and therefore reduces energy losses while delivering maximum output.

Where station post insulators are concerned, choosing to utilize porcelain or composite materials is critical to maintaining long-term stability and performance in the power transmission system. Though both have varying advantages, your decision must be based on the specific needs of your project, external environmental conditions, and long-term performance specifications. This blog will discuss the primary differences between porcelain and composite station post insulators to allow you to make an informed purchase decision for your next order.

Station Post Insulators: Porcelain vs Composite

April 2, 2025

Where station post insulators are concerned, choosing to utilize porcelain or composite materials is critical to maintaining long-term stability and performance in the power transmission system. Though both have varying advantages, your decision must be based on the specific needs of your project, external environmental conditions, and long-term performance specifications. This blog will discuss the primary differences between porcelain and composite station post insulators to allow you to make an informed purchase decision for your next order.

Durability and Mechanical Strength

Porcelain

With over 50 years of manufacturing history, Newell’s porcelain station post insulators have superior mechanical properties. Porcelain exhibits better endurance with high mechanical stress, torsion, and compression resistance and can be used for long-term application in both non-stacking (up to 161 kV) and stacking (230 to 765 kV) uses. Porcelain mechanical ratings include a cantilever strength that is a function of the insulator size.

Composite

On the other hand, composite insulators, made from fiberglass rods with bonded silicone rubber coverings, also exhibit excellent mechanical strength. Newell’s composite insulators, for example, may have mechanical ratings equal to, if not superior to, porcelain, and their cantilever strength will be a function of the insulator’s size. Composite materials are flexible and can flex slightly under mechanical loads without breaking, which is beneficial when subjected to vibration or dynamic loading.

Category: Station Post Insulators, Sub Category: Tapered Stacks, Strength: Extra High Strength, TR Number: TR-369, Typical Application Voltage (kV): 345kV, BIL Rating (kV): 1300kV, Bottom BC (in): 7, Cantilever (lbs): 2050, Height (in): 106, Leakage (in): 231, Top BC (in): 5

Environmental Performance

Porcelain

Porcelain station post insulators offer very high resistance to environmental deterioration. Newell also offers porcelain insulators with an NPRTV® coating, which provides extra protection against industrial contamination and salt spray. The coating further eliminates the requirement for frequent washing and resists power loss due to contamination. Uncoated porcelain, however, may retain contamination more in highly polluted environments, leading to a diminution of performance over time.

Composite

The structure of composite insulators makes them naturally resistant to environmental damage. The silicone rubber housings on these insulators create water-resistant surfaces that protect against the buildup of contaminants. Composite insulators work best in areas with high levels of contamination, including coastal areas and industrial zones. Such insulators reduce the probability of flashover incidents triggered by environmental contaminants.

Electrical Performance

Porcelain

According to ANSI, porcelain insulators exhibit better electrical performance, with impulse-withstand voltages ranging from 95 kV to 2050 kV. They are reliable insulators under high-voltage conditions; hence, porcelain insulators are a safe choice for most utility applications. The longevity of porcelain insulators extends beyond decades because they maintain their electrical properties throughout time.

Composite

According to ANSI, composite insulators are also reliable electrically, with a maximum impulse withstand voltage of 1470 kV. They perform exceptionally well where flashover of environmental contaminants is a problem, as the hydrophobic nature of the silicone rubber housing prevents electrical discharge in contaminated conditions.

Weight and Ease of Installation

Porcelain

Due to their great weight, porcelain insulators present significant burdens for both shipping activities and project installation. A porcelain insulator that works at 110 kV BIL exceeds 16 lbs. The weight invested to enhance strength creates installation challenges for limited access or when working at high elevations.

Composite

Composite insulators are considerably lighter and, therefore, easier to transport and install. A standard composite station post insulator for application with 110 kV BIL installations may weigh as little as 7 lbs, thus allowing quicker, cheaper installation. Composite insulators would be the natural choice, and installation cost and time must be minimized.

Cost and Availability

Porcelain

Porcelain insulators also cost less upfront. Newell’s porcelain insulators can be stocked from inventory with short lead times and rapid delivery, a valuable selling feature compared to the competition. However, the cost of maintaining clean and coated porcelain insulators in filthy surroundings does add up in the long run.

Composite

Even though composite insulators can cost more initially, they do not require more maintenance and survive longer under harsh conditions. Their ability to withstand contamination and need to be cleaned less often can translate to lower overall lifecycle costs in places with high industrial pollution.

Category: Station Post Insulators, Sub Category: Composite, Strength: Standard Strength, TR Number: TR-286, Typical Application Voltage (kV): 115kV, BIL Rating (kV): 550kV, Bottom BC (in): 5, Cantilever (lbs): 1700, Height (in): 45, Leakage (in): 106.3, Top BC (in): 5

Which Should You Choose?

Deciding between composite and porcelain station post insulators ultimately comes down to your project needs. If you want a tried-and-true, cost-effective solution with lower upfront costs, porcelain could be the best option, especially for less extreme environments. However, if you have high contamination or challenging installation conditions, composite insulators might have a better long-term value because they require less maintenance and weigh less.

Making the Right Choice for Your Project

When choosing between porcelain and composite station post insulators, you must weigh your project’s long-term benefits and personal needs. Newell’s extensive inventory of both options provides you with quality products with industry-leading shortest lead times, no matter the choice. Either option, the tried-and-tested dependability of porcelain or composites’ inherent flexibility, Newell possesses what it takes to provide your power transmission work with the best in either event.

The Role of Distribution Insulators in Reducing Power Outages

August 16, 2024

Power outages are disruptive, costly, and frustrating, but luckily, they are often preventable. One critical element in reducing the frequency and impact of these outages is the effective use of distribution insulators. Insulators may seem like a small part of the overall electrical system, but they play an essential role in maintaining the integrity of power distribution networks. By supporting and insulating electrical wires, they help prevent short circuits and faults that can lead to power outages. In this blog, we’ll explore how our distribution insulators at Newell contribute to reducing power outages and improving the reliability of electrical systems.

What Are Distribution Insulators and How Do They Work?

Distribution insulators are designed to support electrical conductors while ensuring that the current does not escape to the ground. They are made from high-quality materials like porcelain, which provide excellent electrical resistance. By keeping wires suspended and insulated, these devices prevent unintended contact between electrical components, which can lead to outages. Newell manufactures a range of insulators, including deadend insulators, line post insulators, spool insulatorslow- and high-voltage pin insulators, and guy strain insulators, all designed to meet the highest industry standards.

Preventing Short Circuits and Electrical Faults

One of the primary ways distribution insulators reduce power outages is by preventing short circuits and electrical faults. Short circuits occur when electrical currents bypass their intended path and flow directly to the ground or other conductors. This can happen due to damage to the wires, weather conditions, or improper installation. By keeping conductors securely in place and insulated, insulators ensure that electricity flows along the correct path, reducing the likelihood of faults that can cause outages. For example, Newell’s spool insulators are dimensionally optimized for a perfect fit, ensuring a reliable connection that prevents malfunctions.

Weather Resistance and Durability

Weather-related outages are a significant concern for utility companies. High winds, rain, snow, and ice can all cause power lines to sag, snap, or come into contact with other elements, leading to outages. Quality distribution insulators are built to withstand harsh environmental conditions. Newell’s insulators, including their high-voltage pin insulators, are made from durable wet-process porcelain that resists wear and tear from weather exposure. This durability ensures that insulators remain effective even in extreme conditions, further reducing the risk of power disruptions.

Minimizing Maintenance and Downtime

Insulators that are manufactured to the highest quality standards reduce the need for frequent maintenance. Poor-quality insulators can degrade over time, leading to increased maintenance costs and more frequent outages. Newell’s insulators undergo frequent quality audits and third-party inspections to ensure reliable field performance. By choosing reliable, durable insulators, utilities can minimize downtime and maintenance, keeping power systems running smoothly and reducing the frequency of outages.

Supporting Modern Electrical Infrastructure

As electrical grids evolve to handle more complex demands, the need for reliable distribution insulators becomes even more critical. Insulators must support increasingly large conductors and withstand higher voltage levels. Newell’s low- and high-voltage pin insulators are designed with top and side grooves optimized for large conductors, ensuring easy installation and a secure fit. This optimization helps utilities keep their systems efficient and reliable, reducing the chances of outages caused by outdated or improperly fitted components.
