Lightning protection LLPD d45z

LLPD d45z

This device is there to protect important networks from direct lightning strikes and back flashovers. Indented to be installed along the protected line, it works perfectly on distribution (sub-transmission) lines with the highest voltage of equipment up to 52 kV.

Operational principle

This product operates on the basis of EasyQuench technology.

d45z can easily be adapted to poles/towers of totally different configuration. This is possible due to various installation options.

  • Highest voltage  for equipment, 52 kV
  • Protects from Direct Lightning Strike
  • Protects from Back Flashover
  • No maintenance is required
