Product Details

● The zine oxide arrester is the most advanced over-voltage protector in the world;Due to make the risistor disc of core componet mainly adopt zine oxide arrester.Compared with the conventional silicon carbide arrester, this presciption of theproduct improvesgr-eatly the volt-Ampere characterisics of the resistor disc andincreased through-current capability at over-voltage so as to dring arad-icalchanges for the characteristics of the arresters.

● Under the circumstance of normal operating voltage, the current through thearrester is just on microampere degree, When suff-ered from over-voltage, thearrester's excellent nonlinear characteristics will make the current through thearrester incrase to several thousand amperse, while the arrester will be under thecirculating state and release over-voltage energy so as to protecting the powertransmission equipments against the demage caused by th over-voltage.

Operating conditions

1. The ambient air temperatures is no higher than +40℃,no lower than -40℃ ;

2. The altitude above sea level dose not exceed 1000-2000m(the plateau ares should be indicated when ordering);

3. AC systen frequency is 50Hz or 60Hz;

4. The power frequency voltage applied to the arrester for a long time does not exceed the continuous working voltage of the arrester;

5. Maximum wind speed does not exceed 35m/s;

6. The earthquake intensity does not exceed 7 degrees;

7. The filthy area should be given clear indication.

Features

The zinc oxide arrester is applied to protect the electrical equimpent in AC power system against the damage resulted from atmospheres over-voltage and operational over-voltage.

Technical performance

The technical performance of the product confirms to GB11032-2000, IEC60099-4,IEEE.C62.11 standard technical requirements.
