Reliable Insulation
Excellent power-frequency and lightning-impulse withstand performance, with stable insulation in humid and dusty environments.
Thermal Stability
Stable thermal expansion helps resist cracking during sudden temperature changes and supports reliable grid operation.
Weather Resistance and Long Service Life
Inorganic ceramic resists UV radiation, temperature cycling and acid rain corrosion.
Custom Pollution-resistant Glazes
Optional glaze formulations for coastal, chemical and heavy-industrial environments help reduce pollution flashover.
