Category:
ZW20 VCB & FZW28 LBS PARTS
Silicone rubber covered epoxy resin bushings for 12/24kV, often referred to as composite or hybrid bushings, combine the high mechanical strength of an inner epoxy resin core with the superior environmental, hydrophobicity, and pollution resistance of a silicone rubber outer shed.

Description
This bushing has an epoxy resin core that ensures good mechanical performances and excellent insulation level. The external coating consists of liquid silicone rubber co-molded on the core that guarantees excellent resistance to degradation caused by atmospheric agents (sandstorms, UV radiations, saline environment, industrial pollution……).
