Composite insulator used for 25kV electrified railway:
Features:
1) End fittings are crimped onto fiberglass rod with voice-operated displacement type crimper
2) 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.
