Silicon pin insulator, mainly made of silicone rubber, is used on high voltage distribution overhead lines of power system, and its voltage level ranges from 6kv to 36kv.

Silicon pin insulator features:
Composite pin insulator with clamp needs good quality of nuts and bolts to ensure its strength and safety.
The top fitting of composite pin insulator is used to support wires and bottom fitting of composite pin insulator is mounted on wooden or steel cross arm.
The diameter of bottom fitting of composite pin insulator also called bolt decided by the strength and the length lies on what is the material of cross arm.
Good resistance to soiling and flashover, high quality and reasonable prices, better anti-pollution ability

Our tests for silicon pin insulator products include Tests on interfaces and connections of metal fittings; Assembled core load-time test; Test of housing: tracking and erosion test; Tests for the core material; and so on.
