Ceramic post insulator

Ceramic post insulator is one of high voltage insulator which always used in the power stations, substations and electrical equipment devices.

Ceramic post insulator

Ceramic post insulator use wet-process porcelain, have high strength.

The cantilever strength from 4kN to 18kN,and usually used on 15kV to 750kV station and substation.

Refer standard for ceramic post insulator:
2. IEC
3. AS
Common type for ANSI standard:

TR-202, TR-205, TR-208, TR-210, TR-214, TR-216, TR-286, TR-287, TR-288, TR-289, TR-291, TR-304, TR-312, TR-362, TR-369, TR391
