Widely Used High End Lightning Zinc Oxide Surge Arrester
The zinc oxide arrester is the most advanced over-voltage protector
in the world. Due to make the resistor disc of core component
mainly adopt zinc oxide arrester.
Compared with the conventional silicon carbide arrester, this
prescription of the product improves greatly the volt-Ampere
characteristics of the resistor disc and increased through-current
capability at over-voltage so as to bring radical changes for the
characteristics of the arresters.
Maior structure is overall moulding by zinc oxide varistor,
electrodes,epoxy resin insulation layer,besides good sealing and
Features excellent,also small volume,light weight,easy movement,
easy to assemble and very well for withstand pollution,meanwhile
against malignant explosion accident like traditional porcelain
