ANSI 52-4 Porcelain Disc Suspension Ceramic Insulator for Transmission Line
Brown Color ANSI Standard 52-4 Porcelain Disc Suspension Ceramic Insulator for Transmission Line
Description:
Disc suspension porcelain insulators are mainly used on high-voltage overhead transmission and distribution lines to support and insulate conductors. The normal type disc suspension porcelain insulators include standard type and large creepage distance type insulators. These insulators are widely used in clean areas and light pollution areas.
