Transformers and package substations for temporary construction site power
Temporary power for a construction site needs a substation that is quick to install and connect, and can then be moved to the next site. We select the transformer and package substation for the crane, site cabins and concrete heating.
- Hermetically sealed oil-immersed transformers (TMG type) — no conservator and no oil maintenance for the whole time on site.
- American-type ZGS package substation: transformer and HV section in one tank, compact, installed on a prepared pad.
- Package substation in a modular enclosure with 10 kV and 0.4 kV switchgear compartments — when metering and several outgoing feeders are needed.
- We size the rating from your loads: tower crane, hoists, site cabins, concrete heating.
