High Voltage Arresters (18kV - 33kV)

Our High Voltage (HV) Surge Arresters (18kV to 33kV) are engineered for heavy-duty protection in sub-transmission and primary distribution networks. Specifically optimized for 24kV and 33kV overhead lines, these arresters are built to handle high-energy discharges and extreme outdoor conditions. The range includes both hydrophobic polymer-housed models—ideal for high-pollution or coastal environments—and rugged porcelain-housed arresters for superior mechanical strength. Designed to meet IEC 60099-4 standards, our HV surge protectors feature advanced explosion-proof designs and reliable pressure relief mechanisms, making them the preferred choice for protecting high-value power assets and ensuring grid resilience against severe lightning activity.
