Pin type insulator makes up of FRP core, silicone rubber housing, composite sheds and metal end fitting. Before the silicone rubber pin insulator test, all samples insulators were carefully cleaned so that all traces of dirt and grease were removed and dried naturally.

Silicone rubber pin insulators could be manufactured by means of moulding technology. The juncture between end fittings and core is totally embedded in composite pin insulators, remedying conventional and traditional seal defects.

Silicone rubber pin insulator test:
Silicone rubber pin insulator is one kind of the composite insulator, which another way of saying is composite pin insulator. According to pollution status of environment, composite pin insulator can be divided into common composite pin insulator and anti-pollution insulator. By insulator tested, our pin insulators can be used in heavy pollution and plateau areas.

Silicone rubber pin insulator application:
Silicone rubber pin type insulators are commonly used to hold conductors in place, separating them from one another and from surrounding structures to form a barrier between energized parts of an electric circuit and confine the flow of current to wires or other conducting paths. Pin silicone rubber insulators include silicone rubber, porcelain and glass. Pin silicone rubber insulator break up the heat-flow path by absorbing radiant heat; include fiberglass, cork, and rock wool.
