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




Technical features
The body structure (base, uprights, supports, roof) is made of steel sheets with a thickness of 25-30/10mm, Sendzimir SZ275 type, galvanized and coated with epoxy resin, suitable for outdoor installations in hostile environments
The box is equipped with vertical angular supports positioned on its four sides and intermediate brackets made in hot-dip galvanized steel sheet with a thickness of 30/10mm
External walls consist of one external layer in galvanized steel sheet 15/10mm, Sendzimir SZ275 type, coated with epoxy resin and one internal layer made of polyurethane insulating panels, with a thickness of 40 mm
Additional internal equipment: medium voltage (MV) switchgears, low voltage (LV) switchgears, power transformer, inverter, SCADA system, electrical installations, fire-fighting system, weather station, cooling system, auxiliary, UPS, batteries, CCTV
