Silent testimony to this fact is the continuing function of the millions of U120B disc suspension insulator units already in service. Although shapes and appearances seem unchanging, today’s disk insulator provides even greater benefits and reliability than in the past. Special features and performance capabilities of U120B disc suspension insulators have been added which significantly assist the transmission line designer.

U120B disc suspension insulator / disk insulator details of technical parameters:

IEC Type U120B
Unit spacing H (mm) 146
Dia. D (mm) 255
Leakage distance (mm) 295
Rated E&M failing load- KN 120
Routine tension load-KN 60
Impact failing load (N.m) 7
Wet power freq. withstand voltage (KV) 40
Lighting impulse withstand voltage (KV) 100
Radio influence voltage Test voltage to ground (KV) 10
