Product Details

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.
