Describe Display

The HY5 series zinc oxide surge arresters deliver reliable overvoltage protection for transmission and distribution networks. Engineered with a robust metal oxide varistor core and weatherproof housing, they effectively clamp transient surges while maintaining low residual voltages to protect sensitive equipment.

 

Available in a broad range of voltage classes and configurations, these maintenance-free arresters suit diverse applications from substations to industrial installations. Their durable construction and stable performance under repeated surge events ensure long-term system reliability and reduced operational costs.
