  • Substation Repair

The need for planned and systematic maintenance of transformer substations is due to the high danger and severe consequences resulting from accidents at such facilities. We include in the range of repair and maintenance works for such equipment:

  • Diagnostics, complete and selective inspection.
  • Checking all the main characteristics of the substation.
  • Add oil.
  • Replacement or repair of worn and failed parts.
  • Measurement of loads and voltage at the transformer substation and associated lines.

Our company carries out current and overhaul repairs of transformers and electrical equipment of substations of the following series: STP, KTP, KTPN, KTPP, MTP, MZhB and others.

Frequently asked questions

The repair time depends on the type: routine repair takes 1-2 days, rewinding takes 3-7 days, and overhaul takes 7-14 days. For urgent orders we work around the clock, and most jobs are completed within 1-3 days.

Yes. We provide a written warranty for all types of work: from 6 months for routine repairs up to 12 months for overhauls and rewinding. The warranty covers factory defects and errors in the repair performed.

Yes. We repair electric motors from any manufacturer — local (AIR, 4A, DAZO) and imported (ABB, Siemens, WEG, Mitsubishi and others). We use original spare parts or high-quality analogues.

Yes, an on-site visit by a diagnostic engineer is available in Tashkent and the Tashkent region. We will assess the motor's condition, perform initial diagnostics and draw up a work plan. The cost of the visit is discussed separately.

In most cases, repair costs 2-4 times less than buying a new motor of similar power. This is especially true for motors above 7.5 kW. See our article "Rewinding or a new motor" for a detailed comparison.

After the repair you receive: a certificate of completed work, a warranty card, and a post-repair test report (insulation resistance, no-load current, RPM). All documents can be handed over to your accounting department for asset registration.
