  • power generators leads in power stations, heat & power plants,
  • industrial plants and factories,
  • connections of electrical equipment in high short-circuit systems,
  • group of connections to single-phase transformers in highly polluted and humid environment.

General characteristics

  • reliable and economical power installations for voltages from to 36 kV and rated current to 30 kA,
  • both indoor and outdoor application,
  • natural cooling,
  • degree of protection up to IP 65,
  • design with:
    • pressurized dry air,
    • space heaters,
    • requested support structures incl. GCB platforms.


  • round conductors (Al 99,5) placed on support insulators inside self-supporting enclosure (screen),
  • dismountable connections (rigid and flexible) to auxiliary equipment and apparatus, prefabricated transport elements (up to 12 m) delivered on site used to connect electrical equipment, expansion joints, t-offs etc. creates a complete transmission-distribution line,
  • self-supporting aluminum enclosure.


  • silicone bushing insulators,
  • electrical apparatus enclosed in special housings.


  • modern technology of design, manufacture and erection make it possible to fit the busduct to individual requirements of the Client,
