The insulator is glazed white or brown on the ceramic part surface and the metal fittings are applied with anti-rusting paint.

Product Description

High resistivity at elevated temperatures reduces the risk of electrical breakdown due to excessive leakage currents.
Surface glaze gives the material a dirt and dust repelling property, which significantly reduces the probability of tracking across the material and also facilitates inspection and cleaning.
Excellent mechanical strength and impact resistance, significantly reducing failure rate due to mechanical stress.
Low decrease of resistivity due to the reduced build-up of conductive surface contaminants in comparison with unglazed insulators.
Low thermal expansion allows the insulator to resist cracking caused by thermal shock.
The insulator is glazed white or brown on the ceramic part surface and the metal fittings are applied with anti-rusting paint.
The ceramic shaft insulator conforms to the Chinese standards of GB/T772-2005 'Technical specifications for high-voltage insulator' and JB/T6746.(1-4)-1993 'ceramic insulator used in electrostatic precipitator', and the IEC series standard is also followed.
With different materials The ceramic shaft insulator can be used under the temperature ≤250℃ or ≤400℃ with the operating voltage ranging from 72~120kV and a torque failing load not less than 1kN·m.
