Traction substations

As part of the work on traction substations to supply power for railway lines, we offer:

• turnkey investments (design and build)
• implementation of investments in the "build" system for entire facilities or their separate parts
• construction, reconstruction, modernization of traction substations supplying railway traction of all voltage levels (LV, MV, 110 kV), in particular:
  
  • cubature infrastructure and general construction facilities, including prefabricated substation buildings
  • installation of foundations, supporting structures for apparatus and railings
  • assembly and adjustment of apparatus, including modular 110 kV bays systems with the use of compact overhead equipment, 15 kV AC switchgear, 3 kV DC switchgear, rectifier sets, auxiliary transformers, reactive power compensation systems, negative cell
  • prefabrication and assembly of cable, security, meters, control and own needs cabinets
  • laying of cable routes and cables of all voltages
  • implementation of remote and local control systems – cabinets for Substation’s Communications Driver, Main Distribution Point and Indirect Distribution Point
  • execution of the earthing system, installation of the earthing grid
  • inspection and post-assembly measurements of primary and secondary parts, commissioning and start-up
• design and construction of supply lines for voltage traction substations – 110 kV cable lines and overhead power lines
• making medium voltage cable systems, excavation and laying medium voltage cable routes, installation of interior and overhead medium voltage cable joints and cable heads
