Gapless Antenna Lightning Arrester Metal Oxide with Safe Operation

Delivery Time:21days per container
Certification:ISO9001/KEMA

0.25~500kV Polymer(Pocelain) Housed Gapless Surge Arrestor Lightning

Product characteristic:

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.

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.

Usual Service Condition:

1) Environment temperature: -40--+40 degree
2) altitude: <1000m
3) 48HZ

4) Power frequency voltage should not be more than continuous running voltag
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.
