Polymeric hoursed metal-oxide surge arrester 75kv
Keywords:Lightning arrester, zinc oxide arrester, surge arrester
Application:The ZnO arrester is mainly used to protect distribution transformer, cable connector and electric equipment from being damaged by lightning impulse voltage and operated over-voltage
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 zine oxide arrester, compared with the conventional siliconcarbide arrester, this presciption of the product improves greatly the volt-Ampere charateristics of the resistor disc and increased through-current capability at over-voltageso as to bring a radical changes for the characteristics of the arresters.
