Product structure:
, Insulation layer: Unique formula and mixing technology ensure the high quality of prefabricated insulating rubber Quality
, Outer semi-conductive layer: prefabricated conductive rubber meets standards
, Arrester core: composed of zinc oxide arrester valve plates treated with special technology
, Copper bottom cover: copper The bottom cover is closely combined with the outer conductive layer of the arrester, making the arrester effectively waterproof and providing a grounding point for the arrester
. Grounding wire: The grounding wire at the lower end of the arrester is used to effectively guide the lightning impulse voltage to the grounding position
