Porcelain disc insulators

Porcelain disc insulators are made into disc shape,that’s why it got this name.The disc insulator has metal fittings on both ends,usually seen as ball and socket type,and also there are tongue and clevis type coupling. Several pieces of ceramic disc insulators are connected together to make up a insulator string.This string are used in electricity power transmission line and distribution line from 11KV to 400KV or even higher.

Currently the ceramic disc insulators we supply are mainly designed and tested according to ANSI standard, which known as 52 series. ANSI 52 series disc insulators include:


These insulators various in dimensions,mechanical load and electrical properties.
