Electric network in India operates under very harsh environments. Industrial pollution, marshy land, hilly and unfriendly terrain, extreme weather, coastal region etc. make insulator contamination flash overs the main concern to the electric utility. Variety of solutions were tried to combat the insulator pollution flash over. Initially Ceramic Silicon Insulators,wholesale composite insulator, wholesales polymer insulator,silicone composite insulators,polymer post insulator,silicone insulator,polymeric insulator,composite polymer insulator,suspension composite insulator,wholesale composite insulator,disc suspension insulator,pin type insulator,polymer insulators manufacturers ,were in use and then the glass insulators were put to use, but these did not serve the flash over issue. The introduction of Composite Insulators(Polymer Insulators) OR Silicone Insulators was a turning point in the 1970s.
These silicone rubber insulators/composite insulators were popular for their pollution resistance and were useful ever in severe/harsh weather conditions. The composite insulators have distinctively hydrophobic surface and are resistant to chemical influence, weathering, UV radiation. The physio chemical and mechanical properties of these rubber composite insulators remain constant over wide temperature range. Hence there are negligible changes in the properties of polymer insulation and no electrical or mechanical failures are experienced.
Composite insulators we offer can be custom specified, manufactured, tested and are reliable for their service life. They are ideal for use in HVAC, HVDC and in most HV application.

We manufacture high voltage insulator 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, Polymer dies insulator, polymer lighting arresster.
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 transportation and installation
5. Not brittle, and reduce the purchasing quantities for spare parts.
