Product Structure

 

1. SEMI-CONDUCTIVE SHIELD INSERT: Semi-conductive insertis molded of semi-conductive EPDM and controls electrical stresses at nose of mating loadbreak product.

2. EPDM INSULATION: High guality sulfur cured EPDM insulation is mixed and formulated in-house for complete control ofinsulating rubber characteristics.

3. SEM-CONDUCTIVEINSERT: Moulded EPDM conducting rubber screen controls electrical stress

4.GROUNDING EYE: Moulded into the external screen for connection ofan earthing wire.

5. STRESS RELIEF: The configuration of the outer screen and the cable adapter provide cable stress relief

6.CONDUCTOR CABLELUG: Aluminum compression connector is sized to ensure a cool running connector with maximum current transfer.

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

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