10 kV complete transformer substations of KTP series

Complete transformer substations of KTP 6(10) kV series are designed to receive, transform, and distribute three-phase alternating-current electric power of 50/60 Hz commercial frequency.

10 kV complete transformer substations of KTP series


The complete transformer substation is suitable for operation under the following conditions:

• altitude above sea level: no more than 1000 m;

• ambient air temperature: from minus 45º C to plus 40º C for climatic category N1; from minus 60º C to plus 40º C for the climatic category NF1 as per GOST 15150;

• environment: industrial atmosphere of type 2 (non-explosive, not containing chemically active gases and vapor in concentration that may cause drop of KTP parameters down to inadmissible values). Interpretation of reference designation.




















Climatic category and placement category as per GOST 15150-69










Low-voltage side class, kV (0.2 as single phase of substation)










High-voltage side class (6 or 10), kV
