Procedures

Features

1).Porcelain insulators are mainly used on high-voltage overhead transmission and distribution lines to support and insulate conductors.
2).Pin type insulators usually serve in coastlands and rainy areas with large creepage distance structure and well flashover performance in wet condition.

our products applies to power station,transmission tower/iron tower ,telegraph pole/wire pole,communciation,transformer,cable/electric cable,wire/electric wire,switch cabinet,meter box,etc.
