0.25~500kV Polymer(Pocelain) Housed Gapless Surge Arrestor
1. Small size,Light weight,resistance to impact,no collision damage
during transportation,flexible installation,suitable for use in the
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
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
Usual Service Condition:
1) Environment temperature: -40--+40 degree
2) altitude: <1000m
4) Power frequency voltage should not be more than continuous
5) Max wind speed should be less than 35m/s
6) Earthquake intensity should be less than 7 degree
7) If used in contamination area, should be noted in advance.
