We offer high quality pin type insulators according to IEC , ANSI, BS standards and customers' specifications .

Voltage class of pin type insulator can be made up to 36 KV ,10 KN.

Especially ANSI Standard pin insulator are in very good finish and high cantilever strength .

for example : 55-2,55-3,55-4,55-5 , 56-1,56-2,56-3,56-4,56-5 etc.
