11kV Composite Polymeric Pin Insulator

The disc insulator silicone rubber housing taken shape by whole injection has good hydrophobicity, Hydrophobicity migration and soil resistance, as well as excellent electrical insulation properties and aging resistance, which could prevent effectively those accidents of pollution flashovers so as to ensure the safe running of high voltage transmission lines.

The modified ECR fiberglass reinforce epoxy resin rod is used as it has good resisitance to high temperature, stress corrosion & acid attack, as well as fine damping action, high tensile strength (>1200Mpa) and resisitance to creep and fatigue insulation quality and mechanical strength of insulators. 

End fittings are crimped onto fiberglass rod with operated displacement type crimper. the insulators with this crimping technique have high mechanical strength and samll dispersion.

The connection location between end fittings & rods is fused with sheds housing by the overall high temperature vulcanized silicone rubber injection molding as it could minimize the interface. the internal radial multi-seal structure effectively guarantee a long term reliability of seal around the connection between end fitting & rods.
