To ensure the stable operation of the power system, the organic composite coated zinc oxide lightning arrester is specially designed for AC transmission and transformation lines. It can be connected in parallel to both sides of the insulator (string), effectively suppressing lightning overvoltage, reducing the lightning trip rate by more than 60%, and significantly improving the lightning protection level of the line. Supports suspended (transmission tower installation) and pillar dual installation modes, suitable for complex environments such as mountainous areas, coastal areas, and industrial pollution areas, and is suitable for 10kV to 220kV AC transmission and transformation systems. The product adopts a high-strength silicone rubber composite jacket and zinc oxide valve plate (ZnO), with a seamless fully sealed structure, capable of withstanding extreme temperatures from -40 ℃ to+70 ℃, resistant to UV aging, salt spray corrosion and chemical pollution, and has a lifespan of up to 25 years without maintenance. Compliant with GB 11032-2000 (equivalent to IEC 60099-4), JB/T 8952-2005 and other standards, widely used for: New energy stations: lightning protection for collection lines of wind farms and photovoltaic power stations Industrial heavy areas: power grid protection in high pollution areas such as petrochemicals and metallurgy Old line renovation: Lightweight design, no need to renovate existing tower structures
