SPARK Composite Polymer Insulator comprises a Core material, End Fittings and a Silicone rubber insulating housing.
CORE ROD: The Core Rod for composite insulator is a Glass Fiber Reinforced Plastic (FRP) Rod. Glass fibers used are of Boron free ECR (Electrical and Corrosion Resistant) grade. When the glass fiber in FRP rod is Boron free, it will not be affected by moisture and even acid. Our FRP rod consists mainly of glass fibers positioned in a resin matrix so as to achieve maximum Tensile Strength. Resin bonded glass fibers not only provides mechanical strength, but also gives electrical insulation.
HOUSING AND WEATHERSHEDS: The Housing is external to the core rod and protects it from weather. Weather sheds are intended to increase the leakage (creepage) distance and to provide an interrupted path.
END FITTINGS: Our Metal End Fittings are made of Forged Steel, Malleable Iron or Cast Iron with high tensile quality. All the fittings exposed to Environment are galvanized and are then attached to Core rod with high precision uniform compression process which does not damage the core rod. The interface between End fitting and Housing is sealed by silicone elastomer with permanent elasticity to protect it against pollution and moisture.
