Composite line post insulator mainly made of silicone rubber, applicable voltage 10kv-132kv, it mainly used in the transmission and distribution lines. Composite line post insulator an aesthetic compact line design can be easily achieved with a substantial savings in the life cycle cost.
Composite insulator line post has three parts: solid core, shed, end fittings.
1. Solid core of composite line post insulator
The solid core of the insulator is made of a high quality, epoxy resin, E-Glass fiberglass rod that has been specially formulated for electrical and mechanical applications.
2. Sheds:
The housing of the insulator is one piece, high temperature vulcanized, injection molded silicone rubber that is chemically bonded to the core rod. This ensures that the interface between the rubber and rod is impenetrable against moisture ingress
3. End fittings
The line end fittings are radially swaged on to the core rod to reduce the stress concentration and to provide the mechanical performance
