Product Details

Small Size Lightning Surge Arrester Polymeric Housed Zno Protection Device

 

Application:

 

The zinc oxide arrester is mainly used to protect distribution transformer,cable connector and electrical equipment from being damaged by lightning impulse voltage and operating over-voltage.

 

Product Advantage:


1. Small size,Light weight,resistance to impact,no collision damage during transportation,flexible installation,suitable for use in the switch cabin.
2. Special structure,the overall compression molding,no air gap,good sealing performance,moisture-proof and explosion-proof
3. Large creepage distance,good hydrophobicity,strong stain resistance,stable performance and reduce operation maintenance.
4. Unique formula of zinc oxide varistor, small leakage current,slow aging,long service life.
5. With DC reference voltage,rectangular flow capacity and high current and large current withstand capacity are higher than standard requirement.

 

Usual Service Condition:


Power frequency:48Hz ~60Hz
Ambient temperature:-40℃~+40℃
Maximum wind speed: not exceed 35m/s
Altitude: not exceed 2000m
Earthquake intensity: not exceed 8 degrees
Ice thickness: not exceed 10 meters.
