Surge arrester

Surge Arrestor 

Features:

1.Has the advantages of small volume,light weight, resistance to impact,transport without damage ,flexible installation,suitable for use in the switch cabinet.

2.Special structure,integrally molded, no gas gap,good sealing performance,moisture-proof, explosion-proof;

3. Big creepage distance,good hydrophobicity,strain resistant capability,stable performance,reduce operation and maintenance;

4.Unique formula of zinc oxide varistor, the leakage current is small,the aging speed, long service life.

5.With the DC reference voltage square wave,flow capacity and large current withstand capability are higher than the national standard.

Conditions of use

1.Power frequency:48Hz~62Hz

2.Ambient temperature:-40 degree to + 40 degrees C

3.The maximum wind speed of no more than 35m/s

4.Altitude not exceeding 2000m

5.No more than 8 degree earthquake intensity

6.Ice thickness is less than 10mm

7.Long applied voltage does not exceed the maximum continuous operating voltage of the rays of the sun:

   solar maximum irradation(1.1kw/mm²)impact has been in the product type test to be considered,if the arrester has in the vicinity of other sources, lighting arrester used for both sides.
