YH10WX-200/520E-220KV gapless line lightning arrester (suspension type) is a maintenance free lightning protection solution designed specifically for 220kV high-voltage transmission lines. It quickly releases lightning overvoltage through gapless zinc oxide technology, reducing lightning trip rate by more than 65%. Compliant with international standards such as IEC 60099-4 and GB 11032, it adopts a high-strength silicone rubber composite jacket that is resistant to ultraviolet radiation, salt spray, and extreme temperatures (-50 ° C to+80 ° C). It is suitable for hanging and installing transmission towers in coastal, mining, and thunderstorm prone areas. Support intelligent monitoring of leakage current, empower grid maintenance, and extend line life by 30 years+
