TRANSFORMATION CABIN 2500kVA

MAIN FEATURESMedium voltage transformer substations equipped in container, complete withLow Voltage switches and Medium Voltage cells, ready for an immediateconnection. They are manufactured on 20 or 40 feet container’s structuresproperly modified, by planning the passing of inlet and outlet cables, by mountingspecific windows with extruded steel counter-frames. They are equipped alsowith internal lighting system, grounding, ventilation or cooling system. They arearranged for a parallel connection on the medium voltage side of the container,through an additional identical transformer station. The transformer substationscan be used in a double manner, both as voltage booster and as transformervoltage reducer.
