22KV composite pin insulator in silicone rubber type is a main type insulator. And composite pin insulators are widely used on HV distribution lines in recently years for its good specifications.

22KV composite pin insulator in silicone rubber type products were introduced in the late sixties. The basic idea consists of the combination of different materials, which perform different duties in the pin insulator function corresponding to their particular strength and properties.

22KV composite pin insulator in silicone rubber type specifications:
For 22KV polymer pin insulators in silicone rubber type, a high degree of standardisation has been achieved for the end fittings made of forged steel or aluminium, which enables the easy replacement of existing conventional insulators by composite solutions.

The glass fibre reinforced resin rod of 22KV silicone rubber pin type insulators is responsible for bearing the mechanical loads, which can be tension, bending or compression, or a combination of all three, depending on the application and load scenario.

The 22KV composite pin insulator in silicone rubber type silicone rubber shed is made by excellent nature of hydrophobic material. The pin type insulator steel end fittings are hot dip galvanized. The thickness of the galvanizing follows the recommendations of IEC 60383.
