Polymer pin type insulators are the same as vertical mounting tie top type polymer line post insulators, and composite pin type insulator include 6kv, 10KV, 11KV, 12KV, 15KV, 20KV, 22KV, 24KV, 25KV, 27KV, 33kV, 35KV, 36KV.

Polymer pin type insulators structures:
Platinum curing, solid high temperature vulcanized (HTV) silicone rubber based on polydimethylsiloxane (PDMS) with aluminum trihydrate (ATH) filler.
Casting steel C 30 or C 40, worked and then hot dip galvanized
FRP core with high tensile strength and bending strength
The clamp-top clamp is in aluminium and can be used with conductors from 10 mm up to 36 mm diameter size.

Polymer pin type insulators applications:
Composite pin insulators can meet the needs of the most demanding power distribution applications, and also can directly replace porcelain insulators.
They play a role in the transmission and distribution lines.
For decades all these polymer pin insulators products have demonstrated reliable performance in various types of transmission and distribution applications all over the world.

The dependability of the Orient Power design has been demonstrated by the excellent performance of nearly 10 million polymer pin type insulators now installed worldwide at voltages from 10 kV to 36 kV.
