Detailed introduction:

product description

     The metal oxide surge arrester is the basis for the insulation coordination of various electrical equipment (transformers, reactors, generators, motors, PTs, CTs, circuit breakers, contactors, etc.) of the power system. The protection performance of the arrester determines all electrical equipments of the power system.

 

Advantages of Metal Oxide Surge Arrester:

1.         It eliminates the risk of spark over and also the risk of shock to the system when the gaps break down.

2.         It eliminates the need of voltage grading system.

3.         At the normal operating condition, the leakage current in the ZnO is very low as compared to other diverters.

4.         There is no power follow current in ZnO diverter.

5.         It has high energy absorbing capability.

6.         ZnO diverters possess high stability during and after prolonged discharge.

7.        In ZnO diverter, it is possible to control the dynamic overvoltages in addition to switching surges. This results in economic insulation coordination.  

 

This product implements the international GB11032-2000 "AC gapless metal oxide arrester", and the composite jacket product simultaneously executes JB/T8952-2005 "Composite jacket without gap metal oxide arrester for AC system" and JB/T9672-2005 "with series gap Metal oxide arrester standard.
