Distribution one- or two-transformer outdoor transformer substations in concrete enclosures BKTP (LE-BTP) with installed power limited up to 2500 kVA are designed to receive three-phase alternating-current of frequency 50 Hz and voltage 6 or 10 kV from overhead or cable incoming lines and distribute 0.4kV
BKTP (LE-BTP) are designed for industrial, urban, civil and rural uses, marginal and cottage development
Conforms to State Standard of Ukraine 31.2-35036863-008:2009.

1 – Advanced transformator substation in concrete enclosure prodused 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
Transformer substation consist of three parts:
– medium voltage switchgear;
– distribution transformer;
– low voltage switchboard.
Medium voltage switchboard consist of cells with vacuum BB-LE, load break VNM-LE or disconnecting switch PVMZ-LE.
The presence of line, sectional, auxiliary or cells with voltage transformer are possible.
Distributional transformer can be oil air cooled on customer’s request.
Load voltage switchboard includes panels with automatic and disconnects fuse switches
