Surge Protection Device (SPD) for Overhead Line

Surge Protection Device (SPD) for Overhead Line (Thermally Protected Lightning Arresters) with thermal protection are designed to provide protection for low-voltage overhead lines, consumer in-house supplies, distribution transformers, and other systems.

Features:

  • Used to protect the terminal equipment/ overhead cable against the effects of overvoltages, which can be installed on overhead lines from low voltage bushing insulator of transformer to point of entry of power line into the building.
  • High discharge capacity due to heavy-duty metal oxide varistors (MOV)
  • Integrated thermal disconnector to be fail-safe and self-protected in case of overloading
  • Fault indication
  • Fire retardant and UV resistant housing, suitable for indoor and outdoor use
  • Easy installation
  • Comply with EN/IEC61643-11, UL 1449 4th, IEEE C62.41, CSA C22.2
