walk-in packaged substations


  • Walk-in concrete substations
  • (Type UF) steel-plate, walk-in, insulated (type SI)

Application areas for the type UF

  • Power distribution substations for power companies and industry
  • Switching stations
  • Transfer stations for wind turbines, CHPPs and solar systems

Application areas for the type SI

  • Power distribution substations for export, especially overseas and to tropical countries
  • Switching stations for export
  • Transformer and distribution substations with air-insulated switchgear up to 36 kV


  • Personnel safety
    • Arcing fault safety (internal fault) through pressure reduction and cooling of arcing gases
    • Penetration safety (penetration from outside) through use of air grids (special profile) which prevent piercing!
    • Internal door hinges which prevent unhinging from the outside (vandalism)
  • Economy
    • Long service life through partitioning of the switchgear spaces to avoid the penetration of dirt and moisture from the transformer space
    • High availability through heat insulation of doors, roof and walls (of steel plate substations) to prevent the formation of condensation on the switchgear
  • Environmental compatibility
    • Electromagnetic compatibility (EMC)
    • Adherence to the 26th BlmSchV (German Federal Ordinance for Pollution Control).
    • Problem-free disposal through use of recyclable materials (concrete, steel, aluminium, copper)
    • Transformer oil sump made of highly-compressed, oil-resistant concrete with special coating, TÜV-certified and monitored.
    • Use in water protection areas is possible
  • Flexibility
    • Modular system
    • Possible to fit various components
    • Multiple choices for the exterior design
