33KV pin composite insulators are used in power distribution systems 33kV for example as tie top and clamp top pin insulators with more 1,000,000 units in service.

The silicone rubber for 33KV pin composite insulators making process is high temperature vulcanization; and they could be manufactured by means of injection whole-molding technology or moulding.

Except 33KV pin composite insulators, we also produce
◆ 11kv, 12kV, 15kV pin insulators
◆ 22kV, 24kV, 25kV composite pin insulator
◆ 35kV, 36kV composite pin insulators

33KV pin composite insulators were introduced in the late sixties. The basic idea consists of the combination of different materials, which perform different duties in the insulator function corresponding to their particular strength and properties.

33KV pin composite insulators consist of silicone rubber housing, shed, end fittings and fiber glass reinforced core rod.
