Technical parameters, electrical diagram, downloads, a description of the type of container transformer station MRw-bS production ZPUE S.A.


MRw bSComplicated designs composed of a great number of MV / LV switchgears, transform-ers, power generators, etc. often do not fit into even the biggest structures (8160 mm x 3060 mm).
ZPUE S.A., as one of few companies on the market, has a fixing system called “MRw-bs” in its offer. It is designed for typical concrete containers, which are prepared based on the needs of individual customers. Storey “MRw-bSP” stations can be used in order to reduce the investment costs of facilities with high installed power demand.

The main advantage of such stations is the concentration of high power transformer units in a small area. The catalogue only presents examples of manufactured stations. It is possible to realize other solutions adjusted to individual needs, including: stations with several transformers with rated power up to 4000 kVA, stations with electric power generator with rated power up to 2000 kVA.

Compliance with the standards

  • PN-EN 62271-202 - High-voltage switchgear and controlgear - Part 202: High-voltage/ low-voltage prefabricated substation;
    + related norms

Localization of the station due to fire safety requirements

The mounting area of the station should be chosen in accordance with the regulation of the Minister of Infrastructure of 12 April 2002, with regard to the technical requirements of buildings localization (Journal of Laws of 15 June 2002, No 75, item 690, with later changes) or local regulations.
Individual cases of localization/placing of the station should be considered on an individual basis and consulted with ZPUE S.A. or with other authorized services (opinion given by fire protection officer).
