Polymer Composite Insulators

Composite Insulators Manufacturer

11-400 kV polymeric insulators or composite silicone rubber insulators are manufactured conforming to international standards & specifications. Earlier insulators were made up of ceramic or glass only but with the advancements in technology the usage of composite insulators has grown to prevent line flash-over triggered by pollution. We are leading Silicone Insulation Manufacturers & Suppliers in India.
