STC-Box eHouse

STC-Box 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.

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
