Product Structure

1.TWO HEAD SCREW: To make sure have a good contact with the apparatus bushing.

2.INSULATION : Moulded EPDM insulating rubber is formulated and mixed in-house to ensu re hig h q uality.

3.INSULATING PLUG: Molded epoxy insulating plug provides excellent electrical, thermal and mechanical reliability.

4.SEMI-CONDUCTIVE INSERT: Moulded EPDM conducting rubberscreen controls electrical stress.

5.STRESS RELIEF: The configu ration of the outer screen and the cable adapter provide ca ble stress relief.

6.GROUNDING EYE: Moulded into the externalscreen forconnection ofan earthing wire.

7.SEMI-CONDUCTIVE SHIELD: Moulded EPDM conducting rubber mates with the cable screen to maintain screen continuity and ensure that the assembly is at earth potential.

8.CONDUCTOR CABLE LUG: Aluminum compression connectoris sized to ensure a cool running connector with maximum current transfer
