1. Small size, Lightweight, 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. The 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 requirements.
