Detailed Description

YH10W5-12 Substation Surge Arrester without Gaps, KEMA Description: YongDe Surge Arresters can be applied to a variety of systems including substation equipment, AC-DC converters, railway power system and power distribution units ranging from 0.25kV to 765kV systems. These surge arresters demonstrate excellent protection properties. YongDe surge arresters incorporate YNR elements (YongDe Non-linear Resistor ZnO Elements) with superior non-linear voltage-current characteristics, high quality and reliability. Metal oxide type surge arresters offer such special features inherent in the gap-less structure, such as a quick response to surge voltage, high energy dissipation capability, safe operation, compactness / lightweight and freedom from pollution. 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.
