PST-b 20/630

Technical parameters, electrical diagram, downloads, a description of the type of container transformer station PST-b 20/630 production ZPUE S.A.

{tab Characteristics}

In case the “conventional, on-ground” station cannot be placed owing to architectural limitations, the only solution is underground stations. The underground transformer station is a leakproof, monolithic concrete container adapted to be placed under the ground, with medium and low voltage switchgears installed inside. MV (TPM, Rotoblok SF) and LV (RN-W) switchgears are independent elements of the station. The station can be installed on the pavement, square, etc.
Bilges between two floors allow for proper functioning even when surface rain water leaks through the ventilation holes. Water-proof cable glands and tight concrete housing ensure reliable and long-term work of the station.
