KTPK (PACKAGED TRANSFORMER SUBSTATION OF THE CABIN TYPE)

| High voltage complete devices

DescriptionTechnical data

Description

The packaged transformer substations of the cabin type with the 6 or10 kV voltage (herein after KTPK) are designed for power supply of agricultural users, separate settlements and industrial facilities, construction operations and various industrial activities in areas with moderate or cold climate.

The KTPK substations can not be operated under the following conditions:

  • under conditions of jolting, vibrations and impact effects;
  • power infeed on the lowest voltage side;
  • installation in explosion and fire hazardous areas according to the Electrical installation code and special environments according to GOST 24682-81.

Normal functioning of the substations is provided under the following conditions:

  • installation altitude above the sea level – not more than 1000m;
  • installation in explosion and fire hazardous areas according to the Electrical installation code and special environments according to GOST 24682-81.
