Distribution mast-mounted one-transformer outdoor terminal type substations KTPm (LE-TPM) with installed power limited to 250 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

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

LE-TPM is European-lever advanced alternative to traditional mast-mounted substation KTPm 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.

Transformer substation is divided into three compartments:

— medium voltage switchgear;

— distribution transformer;

 — low voltage switchboard.

Substation overhead incoming lines are connected to medium voltage through a disconnector RLNDMz-LE (delivired on customer’s requirement) with operating mechanism and mounting frame that installed directly on middle voltage pilon.
