General description
Technical information

Advantages

  • Attractive appeareance.
  • The equipment is installed indoors, which eliminates the impact on the equipment of the external environment and allows the maintenance of equipment inside the building.
  • KRU-SESH-65 has withdrawable part, which allows easy maintenance. Possible to be manufactured as a whole if necessary.
  • The possibility of transporting blocks by any type of transport, both railway and road.
  • Substation is supplied with ready-made units, which eases and shortens the time of installation of the substation.
