Repair of machine and devices
The main program of our activities are repairing all types of engines:

  • Induction motors up to power output 400 kW.
  • High-tension motors up to power output 2,8 MW.
  • Direct–current motors up to power output 5 000 kW.
  • Synchronous motors up to power output 3 000 kW.
  • Generator repairs up to power output 20 MW.
  • Transformer repairs up to power output 1,6 MVA.

Other activities in this part is the repair of transformers up to 1.6 MVA power for reasons of ensuring comprehensive customer service we provide further repair of rotary and static welders, dynamos, starters and alternators, hydraulic brake release, special gearboxes and vibrators. Within the comprehensive services we provide welding shaft by MIG, MAG methods and repair of mechanical engine parts. Rotating part dynamically balance weighing to 3 t and a length of 4 m in diameter up to 1.8 m balancer SCHENK according to CSN 01 1410. The activities of the Centre, we also offer repairs of burden electromagnets, manufacture and repair startup resistors, repair manual el. tools. We provide motor setting into horizontal and vertical plane by laser.
