There is a wide range of polymer insulator offered by us that has two parts, one is glass fiber reinforced epoxy resin rod-shaped core and the other is silicone rubber or EPDM (ethylene propylene diene monomer) made weather sheds. The rod-shaped core is covered by weather sheds. Weather sheds protect the insulator core from the outside environment. Insulator (composite) is an electrical device consisting of insulation section made of polymer materials and metal fittings. It is made for use in over-head distribution lines using bare or covered conductors. It has a fibre rod surrounded by outer sheath of some polymer. The polymer insulator is made in various design and specifications.
