Distribution one-transformer outdoor terminal type substations KTPv (LE-NPV) 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 with cable or cable-overhead type outgoing feeders
Applications
KTPv 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 and temporary power service
LE-TPV is European-lever advanced alternative to traditional substation with air input KTPv which differs from typical by higher security level and universal completion. LVEP “Lider Electrik” is able to develop and manufacture items with differing parameters and characteristics.
