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.

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.

Short Lead Times to Enable Significant Infrastructure Projects

One of the best advantages that Newell offers is its commitment to holding a robust supply of high-voltage insulators in stock. Unlike its rivals, a hands-on stock indicates insulators are almost always available for shipment. For offshore wind farm developers, this equates to shorter program durations and lower incurred costs related to delays.

Newell’s quick response to the market assures that it is a dependable ally in this speed-of-light system of renewable power, whether utilities, contractors, or distributors are being supplied.
