Product Structure

1.Insulating layer: High quality sulfur cured EPDM insulation is mixed and formulated in-house for complete control of insulating ru bber characteristics.

2.Semi-conductive shield: Molded semi-conductive EPDM shield meets requirements ofANSI/IEEE Standard 592.

3.Arrester core: Compose of the zinc oxide lightning arrester valve slice which th rough special process treatment.

4.Copper bottom cover:The copper base cover is tightly combined with the outer conductive layer of the arrester to make the arrester waterproof and provide the grounding point for the arrester.

5.Ground wire:The grounding wire on the lower end of the arrester is used to effectively connect the impulse voltage to the grounding position.
