mental-oxide surge arrester

Product Description

Basic principle:

the zinc oxide arrester is the most advanced over-voltage protector in the world .Due to make the risistor disc of core component mainly adopt zine oxide arrester .Compared with the conventional silicon carbide arrester ,this presciption of the product improves greatly the volt-ampere characteristic of the resistor disc and increased through-current capacity at over-voltage so as to during a radical changes for the characteristic of the arrester.

   Under the circumstance of normal operating voltage ,the current through the arrester is just on micro-ampere degree ,when suffered from over-voltage ,the arrester’s excellent nonlinear characteristic will make the current through the arrester increase to several thousand amperse ,while the arrester will be under circulating state and release over-voltage energe so as to protecting the power transmission equipment against the damage caused by the over-voltage.

Normal service condition:

1.The ambient air temperatures is not  higher than **0°c,not  lower than**0°c.

2.The altitude above sea lever doesnot exceed ********0m.

3.AC system frequency is *0HZ or *0HZ

Application&Characteristics

They apply to protect the electrical equipment in AC power system against the damage resulted from atmospheres over-voltage and operational over-voltage.

Technical performance:

The technical performance of the product is conform it to GB*********0,IEC******4,IEEE.C*2.*1 standard technical requirements.
