Introduction

Porcelain disc suspension insulator is one main kind of high voltage insulators, used on transmission and distribution power lines, used for 10kV to 1000kV. Porcelain disc suspension insulator can be divided into normal insulator and anti-fog insulator used in light and heavy contamination areas. Porcelain disc suspension insulator is designed in disc shapes and commonly used in suspension strings. The voltage depends on the number of disc suspension insulator.

ANSI series suspension type Insulator
Suspension type insulator: Suspension type insulator is a common used type of insulator for transmission and distribution lines, it is made by wet process method. Most of suspension insulator strings is popular insulator and gathered two or more suspension type insulators to suit for different voltage class.

IEC series disc Insulators
1. IEC normal disc insulators: porcelain disc insulators are designed in disc shape, the insulator end fittings are main part of disc insulators. The types of porcelain disc insulators fittings have ball & socket, clevis & tongue. We can supply porcelain disc insulators up to 530kN, only several company can reach that.        

2. IEC anti-pollution porcelains suspension insulator
Porcelain suspension insulator can be divided into normal insulator and anti-pollution (fog) insulators which used in any pollution level areas. Anti-pollution (fog) insulators can be divided into bell type insulator, double shed type insulator, and triple shed type insulator and Aerodynamic type insulator.
