33KV post composite polymer insulators are our stronger composite insulator produced by us. We also produce all kinds of post Insulator designed for stations, switches, disconnectors, etc.


Technical data of 33KV post composite insulator


Rated voltage


Rated mechanical bending load


Structure height


Min nominal creepage distance


1min power frequency wet withstand voltage (kV)

Full wave lightning impulse withstand voltage peak value (kV)

FZ-36 / 3








Why choose GaoN:

1) We produce post insulators cores with best materials from 2001.

2) HTV silicone rubber is also produced by us with high quality and good treatment.

3) We also invested metal fitting workshop in new factory which can control and fast delivery and good size and good galvanization thickness.


The advantages of silicone rubber composite post insulators:
◆ Excellent mechanical strength
◆ Good dielectric performance
◆ Light weight and is easy for installation
◆ No need insulator cleaning
◆ Low costs for transportation

◆ No broken during transportation and handling and installation

What is most important: we can produce all material of composite insulators by ourselves at same production center, we are also only insulator maker in China who can reach this level.
