Product Introduction

Disc Insulators are used in the transmission and distribution line of electrical power. Usually discs bolted together to form a string for the different voltage level line. According to the polluted conditions or regions, disc insulators can be divided into normal type and Antipollution-type. According to the coupling, it can be divided into Ball, Socket type and Clevis type .All metal parts assembled are hot dip galvanized. The coating thickness can be increased or zinc sleeve can be added as per customers' requirements. 'w' & 'R' clips are made of bronze or stainless steel which is stretchy and anti-corrosive. Glazed color available: white, brown, gray, blue and etc.

Standard for Disc
