Product characteristic

1.Small size,Light weight,resistance to impact,no collision damage during transportation,flexible installation,suitable for use inthe switch cabin.

2.Special structure,the overall compression molding,no air gap,good sealing performance,moisture-proofand explosion-proof

3.Large creepage distance,good hydrophobicity,strong stain resistance,stable performance and reduceoperation 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.
