We VPTPL manufacturing Composite Silicone Polymeric Insulator to comply with IEC 61109, C29-11-1989 and international standard with latest amendment.

Composite insulators were introduced when time demand to require a better technology then ceramic or glass insulator. VPTPL start manufacturing Composite Silicone Polymeric Insulator with different combination of high quality silicone materials and it end fitting made of metal, such as forged steel or SG Iron casting.

We are using ECR glass fiber reinforced resin rod which forms the core of the insulator is responsible for bearing the mechanical loads and ECR is providing Environment protection. The insulator type is depending on its requirement like tension, suspension or bending. Polymeric insulator are two type Disc and Line Post Insulator which divide in further various categories. Polymeric Insulator advancements in technology the usage of composite insulators has grown to prevent line flash-over triggered by pollution.
