YH5WZ-51/134 pedestal free lightning arrester is designed specifically for 10kV-220kV power transmission and transformation systems. It adopts a pedestal free direct installation structure, simplifying the installation process and reducing construction costs. Its core is composed of high-performance zinc oxide valve plates (ZnO) and composite silicone rubber jackets, which can quickly discharge lightning overvoltage (10kA, 8/20 μ s) and reduce the line lightning trip rate by 65%+. Compliant with GB 11032-2000 (equivalent to IEC 60099-4) and JB/T 10497-2005 standards, suitable for extreme environments ranging from -40 ° C to+70 ° C, resistant to salt spray and UV aging, suitable for the following scenarios: 1. Tower direct installation: without the need for an additional base, it can be directly suspended from the cross arm or frame of the transmission tower. 2. High pollution industrial zone: designed with a super large creepage distance, capable of withstanding level IV pollution. 3. Mountainous areas/wind farms: Lightweight structure (30% lighter than traditional models), excellent wind and vibration resistance.
