Switch Disconnector NXS700001

Switch Disconnector NXS700001

Overhead Load Break Switch remote controlled installed on MV three-phases 24kV networks, it will isolate automatically a faulty part of a network and thus allows to re-energize all the remaining healthy network.

  • Opening and closing under severe weather conditions, and easy installation on poles thanks to its high level of integration (MV transformer embedded in the SF6 chamber)
  • Two equipment in one, a load break switch and a disconnector
  • Rescue manual command by a telescopic adjustable linkage or by a 3 positions hook stick command
  • Maintenance free
  • Consult us to define your needs (options, packaging, etc.)
