The shielded design of these rear-mounted arresters, with an external semi-conductive layer, ensures the personal safety of installation and maintenance personnel as well as the safe operation of equipment. In addition, their unique properties—UV resistance, aging resistance, water resistance, and moisture resistance—guarantee safe and reliable operation even in harsh environmental conditions. When paired with European-style front-end connectors, these rear-mounted arresters help ensure the safe operation of the power grid.
Product Structure
● Insulation layer: A proprietary formulation and blending technology ensures the superior quality of the preformed EPDM insulating rubber. Outer semiconductive layer: The preformed EPDM conductive rubber complies with IEEE Standard 592.
● Arrester core: Composed of zinc oxide arrester valve discs that have undergone special processing.
● Copper Base Cover: The copper base cover is tightly bonded to the arrester’s external conductive layer, effectively waterproofing the arrester and providing a grounding point.
● Grounding conductor: The grounding conductor integrated at the lower end of the surge arrester, designed to effectively divert lightning-induced surge voltages to ground. Inner semi-conductive layer: A pre-fabricated EPDM conductive rubber layer that effectively controls electrical stress.
● Double-ended bolts: Tin-plated copper bolts ensure tight mating between the conductor and the bushing.
● Insulator end cap: provides insulating and sealing functionality for the product.
