Ceramic Disc Suspension Insulator/Porcelain Suspension Insulator/Suspension Insulator

Disc Suspension Porcelain Insulator is used for insulation and supporting in high voltage overhead transmission and distribution lines. They are usually connected and assembled into insulator string and used on different levels of line voltage.

Connected fitting type: ball & socket type; clevis & tongue type
Strength can be 40 KN, 45KN, 60KN, 70KN, 80KN, 100KN, 110KN, 120 KN, 125KN,160KN, 210KN, 300KN

According to different use environment and region, the insulator can be divided into standard type and aiti-pollution type.

Standard suspension insulator:

ANSI type:

52-1, 52-2, 52-3, 52-4, 52-5, 52-6, 52-8, 52-9 according to ANSI C29.2

IEC type:

U70BL, U70BS, U100B, U120B, U160B, U210B, U300B according to IEC383, BS137

The fog type has big creepage distance. According to the shed shape and structure, the fog type disc suspension insulator can be devided into double-shed anti-pollution insulator, tri-shed anti-pollution insulator, aerodynamic suspension porcelain insulator and bell-type anti-pollution suspension insulator.

Fog type anti-pollution ceramic disc suspension insulator:

double shed suspension insulator three shed suspension insulator

According to connected way, the suspension insulator can be devided into ball and socket type & clevis and tongue type. The surface of the cap and pin ball of insulator should be hot dip galvanized. If the area is highly polluted, the pin ball can be added the zinc sleeve. The locking device of W and R spring split is made of bronze or stainless steel. They have good flexibility and anti-corrosion nature.
