High Voltage (HV) Surge Arresters

High Voltage (HV) Surge Arresters

In high-voltage networks, surge arresters serve as a core protective component to mitigate the effects of lightning strikes and overvoltages caused by switching operations within the grid. Since these events can severely impact transformers, cables, and switchgear, the protective measures must be accurately matched to the system’s nature and operational conditions.

Netzer A.L. Electrical Engineering supplies high-voltage surge arresters based on gapless Metal Oxide (ZnO) technology. These solutions are tailored for installation on overhead lines, in substations, and in indoor facilities, in full compliance with standard requirements and project specifications.

Our Supply Scope Includes:

  • Polymeric Surge Arresters for Outdoor Applications

  • Surge Arresters for Indoor Facilities and Switchgear

  • Monitoring and Control Accessories for assessing arrester status (such as surge counters/monitors)

  • Arrester Customization for various voltage ranges in MV/HV systems

Suppliers and Manufacturers

Netzer partners with world-leading international manufacturers in the field of surge arresters and grid protection, including:

  • Shreem

  • MacLean Power Systems

  • Elastimold (Hubbell)

The equipment is selected in strict alignment with the project’s engineering requirements, environmental conditions, and grid characteristics, ensuring seamless integration into both existing and new protection schemes.
