Zhengzhou Orient Power Co., Ltd a high voltage insulator supplier. Now we focus on the voltage of 10kv-500kv series composite insulators,  also known as polymer insulators or silicone rubber insulators, which include suspension long rod silicone rubber insulators, pin type composite insulators, station post polymer insulators, cross arm silicone rubber insulators, electrified railway polymer insulators, and so on. The products of our company have passed the test conducted by National Power Network Electrical Equipment Test Centre and Production Quality Test Centre of Ministry of Power Industry...
Advantages of polymer insulators:
As the replacement of porcelain insulators, silicone rubber composite insulators have many advantages:
1. excellent anti-pollution performance, suitable for high polluted area
2. free of cleaning, economical maintenance and suitable for difficult maintenance area
3. no need of zero value check
4. light weight, easy and economical to transprotation and installation
5. not brittle, and reduce the purchasing quantities for spare parts
