BCTP consists of precast concrete elements:

- aerial unit distribution device 10 kV (HVSG);

- aerial unit power transformers and the distribution device 0.4 kV (LVS);

-underground block under the block of the high voltage switchgear;

-underground block under block low voltage switchgear;

-aerial unit PDU to install equipment 0.4 kV (left or right);

-underground block under the block PDU (left or right).

In underground and aboveground provided embedded elements, which when mounting welded together, providing fixation of the product in the workplace position. T./F. 4922-305368 ;8-903-6471471
