  • 33kV composite surge arrester
  • Product introduction
  • 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:

    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.

    Long-term applying voltage does not exceed the maximum coutinuous operating voltage.


    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.
