Transformer Stations

are the connection between the medium-voltage level and the low-voltage grid for power supply companies, local authorities as well as industry and commerce.

Transformer stations are mainly installed inside buildings according to VDE 0101, in concrete substations or in stations made of sheet steel or plastic according to DIN VDE 0671-202.

We provide building up, maintenance and repair of transformer stations.

For new plants, accessible transformer stations or non-accessible compact stations in various versions and dimensions of diverse manufacturers are used.

Key components of a transformer station are:

  • building / housing
  • medium-voltage switchgear (air- or gas-insulated)
  • at least 1 transformer (oil-immersed or cast-resin)
  • low-voltage switchgear
  • optionally: measuring device
  • installation and cabling
  • protective equipment
  • earthing system


Additionally, the technical connection conditions of the grid operator or for internal stations the factory specification of the operator will be considered.
