Distribution one-transformer outdoor terminal type substations with cable input KTPk (LE-TPK) with installed power limited to 1000 kVA are designed to receive three-phase alternating-current of frequency 50 Hz and voltage 6 or 10 kV from overhead incoming lines and distribute 0.4kV to transformer earthed neutral systems

  

Applications

KTPk are designed for use in ring-system and distribution network of petrol service stations. They can supply both civil and industrial uses, agricultural facilities and other objects of the same capacity with electrical infrastructure similar conditions

LE-TPK-ХХХ/ХХ/0,4 ХХ

1 — Advanced distribution transformer substation with cable input produced by LVEP “Lider Elektrik”;

2 — Transformer rated power, kVA;

3 — MV rated voltage, kV;

4 — LV rated voltage, kV;

5 — Climatic region and placement category under GOST 15150-69

 

Transformer substation is divided into three parts:

— medium voltage switchgear;

— distribution transformer;

— low voltage switchboard.
