Distribution consumer power one- and two-transformer indoor substation KTPSN (2 KTPSN) ((LE-TPVU (LE-TPVU-2)) with installed power limited to 2500 kVA are designed to receive three-phase alternating-current of frequency 50 Hz and voltage 6 or 10 kV with or without reserve power supply incoming lines and distribute 0.4kV to transformer earthed or insulated neutral systems
Reference designation structure:
1 2 3 4 5 6
LE-TPVU-Х-ХХХ/ХХ/0,4 ХХ
1 — Advanced transformer substation produced by LVEP “Lider Elektrik”
2 — Number of used transformers (in case of one transformer number is not mentioned);
3 — Transformer rated power, kVA;
4 — MV rated power, kV;
5 — LV rated power, kV;
