Drawing of ANSI 55-4 11kV Ceramic Pin Insulator
Porcelain or ceramic pin type insulator consists of a single piece of ceramic or two pieces of ceramic components which permanently assembled together by cement.
Porcelain or ceramic pin type insulator is mounted on a supporting structure by an insulator pin or spindle. Unless otherwise stated, the pin type insulator does not include the insulator spindle(pin).
The voltage of porcelain or ceramic pin type insulator is 11kv or 12kv, 15kv, 22kv or 24kv, 33kv or 36kv pin insulator.
ANSI 55-4 11kV Ceramic Pin Insulator has following technical data:
