Complectation

Transformers of the DTT and TC(Z) series on voltage 6 (10) kV are intended for power supply of general purpose consumers.

Transformers are intended for operation in areas with moderate climate i.e. for operation under shelter or indoors (U3 design according to GOST 15150-69). At the same time:

  • The environment is not explosive, does not contain any current-conducting dust, aggressive gases and vaporsin concentrations that destroy metals and insulation;
  • installation height above sea levelis not exceeding 1000 m;
  • mode of operation is continuous;
  • ambient temperature is from -45 to +40 C;
  • the transformers are not designed to work in conditions of shaking, vibration and blows.
