Silicon Insulator

We offer and deal in wide range of Silicon Insulator. Available in varied specifications of length and sizes, our high quality rubber Silicon Insulator is capable of withstanding severe working conditions and is highly reliable.

Silicon Insulators

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 Electrical Insulators 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 sever / 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:

Silicon Pin Insulator

Silicon Post Insulators offered comprise high voltage insulators from 10kv-500kv. Also known by the name of Polymer Post Insulators or silicone rubber insulators, these are light weight, have high mechanical strength, feature lower leakage current as well as provide for low installation costs with minimum chances of line failure. Here, our expertise lies in making these available in different colors and in finishes including being stressed in tension, compression as well as in combined stresses up to specified limits.

Disc Suspension Insulator

We manufacture high voltage insulator 10kv-500kv series Disc Suspension Insulator, 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 dese insulator, polymer lighting arrester.

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.
