Polymeric Housed 42kV 55kV 60kV 72kV 73kV 144kV 146kV Zn Oxide Arrester Of Power Station Type Lightning Surge Arrester

Polymeric Housed Surge Arrester difference between this kind of arrester and traditional arrester is that it has no discharge gap and USES the non-linear characteristic of zinc oxide to discharge and break. The product improves greatly the volt-ampere characteristics of the resistor disc and increases through-current capability at over-voltage.

    Specification:

    Product Features:

    1.Small in size, light in weight, collision-resistant, free from damage during transportation, and flexible in installation, making it suitable for use in switchgear cabinets.

    2.Adopting a special structure with integral molding, it has no air gaps, excellent sealing performance, and is moisture-proof and explosion-proof.

    3.It features a large creepage distance, good hydrophobicity, strong pollution resistance, and stable performance, which reduces operation and maintenance work.

    4.The zinc oxide resistor disc with a unique formula has small leakage current, slow aging rate, and long service life.

    5.Its actual DC reference voltage, square wave current-carrying capacity, and high-current withstand value are all higher than the national standards.
