High Voltage Insulation

High Voltage Insulation

Electrical insulation is essential to all modern electrical energy and power system to provide reliability, availability and power density. At GE Research, we tackle the complicated problems of insulation for over voltages arising in power systems in harsh environments with materials and processing technologies to address the multi-stresses effects of electrical-mechanical-thermal-environmental on life. We also develop new insulation materials and technologies capable of withstanding repetitive over voltage surges, quick heat transfer (dissipation) and greater than 300 ºC to meet ever increasing needs for electrification in propulsion, transportation and urbanization.
