*1KV lightning
arrester Appliation:
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
Keystone:
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.
