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.
