eHouse

The eHouse, or switching station, is an insulated transportable medium-voltage (MV) compact substation. It is a modular structure, that can be set up accordingly to customer’s needs and it is divided into several sections and assembled on site. It is a versatile product that can be supplied either completely assembled or in an "assembly kit" format.

It is equipped with power distribution components:

  • Medium voltage switchgear (up to 40.5 kV)
  • Low voltage switchboard
  • Automation system for the control and supervision
  • Inverter, bus duct, auxiliary equipment
