YH5WZ-51/134Q

YH5WZ-51/134Q gapless lightning arrester is designed specifically for 10kV-220kV high-voltage transmission and transformation systems, and is a high-performance maintenance free lightning protection device. Adopting improved zinc oxide valve plates (ZnO) and reinforced composite silicone rubber jackets, it has better lightning overvoltage discharge capability (12kA, 8/20 μ s), significantly reducing lightning trip rate by more than 70%. Compliant with GB 11032-2000 (equivalent to IEC 60099-4) and JB/T 10497-2005 standards, suitable for extreme environments ranging from -45 ° C to+75 ° C, resistant to salt spray and industrial chemical corrosion, suitable for the following scenarios: 1.Strict industrial zone: V-level pollution tolerance, suitable for high pollution environments such as petrochemicals and metallurgy. 2.New energy stations: lightning protection for collection lines of wind farms and photovoltaic power stations. 3.Upgrade of old power grid: Compact design, compatible with existing towers or structures, without the need for infrastructure renovation.
