1 – Advansed contairized transformer substation produced by LVEP “Lider Elektrik”
2 – Number of used tranformers (in case of one transformer number is not mentioned);
3 – Transformer rated power, kVA;
4 – MV rated voltage, kV;
5 – LV rated voltage, kV;
6 – Climatic region modification and placement category under GOST 15150-69
Transformersubstation consist of three parts:
– medium voltage switchgear;
– distributional transformer;
– low voltage switchboard.
Medium voltage switchgear includes input and transformer cells and according to the project may apply line, sectional, auxiliary or cells with voltage transformer.
Medium voltage cells are equipped with vacuum BB-LE, load break VNM-LE or disconnecting switch PVMZ-LE on customer’s request.
Distributional transformer can be oil air cooled
Load voltage switchboard consist of input, line sectional panels with automatic and disconnect fuse switches
