Transformers and complete transformer plants

Tens of thousands of explosion protected transformers and transformer plants produced by Donetsk UkrNIIVE factory are in use on mines and delfts of Ukraine, Russia and other CIS countries.

For investors, businessmen, specialists, who use transformer equipment we propose the following:

  • Development and manufacture of dry transformers and transformer plants in explosion protected execution with power up to 2500 kW·А, voltage of second side up to 3 kV for coal, oil, chemical, mining and other fields of industry with difficult electronic equipment usage conditions;
  • Transformers and transformer plants tests with issue of correspondent testing protocols;
  • Upgrading of outdated transformer plants (TSSHVP and TSVP series) which are currently in use
  • Guarantee average and major repairs of mining explosion protected transformers and transformer plants with power from 100 up to 1000 kV·А;
  • Independent examination of transformer equipment currently in use in the part of estimation of its technical condition and possibility of its further usage;
  • Issue of defect lists for the transformer equipment in order to determine the possibility and value of repair, issue of the conclusions concerning possibility of the equipment retirement;

UkrNIIVE carries all works on the contract conditions.

According to the agreements with the client’s urgent works execution and service provision is also possible.

Electrical machines

The accumulated experience, high qualification of specialists, wide production potential allows developing, putting into production and manufacture any new highly effective electrical motors with improved technical characteristics.

Electrical device testing laboratories are equipped with modern testing stands and have the possibility to:

  • carry out tests of electrical devices with any power and any purpose according to the requirements and methodic described in GOSTs or according to the technical conditions and programs proposed by the client;
  • perform upgrade of outdated electrical motors;
  • independent examination of electrical motors currently in use in the part of estimation of its technical condition and possibility of its further usage;
  • Issue of defect lists for the electrical motors in order to determine the possibility and value of repair with issue of the conclusions for the possibility of the equipment retirement.
Electrical drives control systems

We propose to perform complex manufacture examination on the contract conditions together with energy and technology departments in order to develop technical and economic assessment and recommendations concerning upgrade of the manufacture with highly effective frequency controlled electrical drives, to develop typical electrical drive schemas connected to the certain manufacturing conditions with posterior help provision in the part of contracts conclusion and supply of frequency controlled electrical drives either for explosion hazardous manufactures or in ordinary industrial execution.

After supply of electrical drives we are able to perform contract supervision and calibration works and also perform service for the equipment.

Furthermore, we are able to:
