Composite housing metal oxide surge arresters with low residual voltage, IEC 60099-4 compliance, and integrated lightning/surge protection.

Our lightning arresters are classified according to IEC 60099-4 standards, with model letters indicating specific application categories: S Series (Station): For substations and power plants, offering high energy absorption capacity Z Series (Distribution): For overhead distribution lines and network protection D Series (DC): For HVDC applications and DC traction systems R Series (Capacitor Bank): Specially designed for capacitor bank protection against switching surges T Series (Traction): For electrified railway systems and traction power supply Each series is engineered to meet the specific technical requirements of its application environment, ensuring reliable overvoltage protection in compliance with international standards.

The series of composite jacket metal oxide arresters are mainly used to protect, Distribution transformers, Box-type substations (compact power stations), Cable heads and terminations,Pole-mounted switches, Substation electrical equipment. They also suppress re-ignition overvoltages generated by vacuum switch or oil switch switching of capacitor banks, protecting the capacitor banks from overcurrent damage. Additionally, these arresters protect the insulation of generators, engines, and motor neutrals from atmospheric overvoltages and operating overvoltages.
