Repairs, Overhauls and Maintenance Service of Electrical Equipment

We perform major repairs (stators and rotors rewinds), day-to-day repairs and mending of electrical rotating machines of low and medium voltages ( 0.4 – 10.5 kV ), including:
   • AC motors (both squirrel-cage and slip-ring motors),
   • induction generators,
   • DC motors and generators,
   • generators and exciters,
   • special-grade motors,
   • explosion-proof motors (EX).

Scope of operations performed during repairs includes:
   • insulation replacement and stators and rotors magnetic sheets packing,
   • winding (coils) manufacture,
   • "F"-grade insulation stators rewinding (winding replacement),
   • rotors’ squirrel-cages replacement and revamping,
   • manufacture and regeneration of motor rotors’ shafts,
   • bearing discs regeneration and insulation,
   • temperature sensors installation in rotors’ winding and in bearing units,
   • anti-condensation heaters installation in motor rotors,
   • commutators repairs,
   • regeneration of slip-ring heads and brush-holders,
   • rotating assemblies balancing.

The correct performance of the work is confirmed by inter-operation and final tests results, including those of insulation system and bearing units, the tests being carried out in compliance with the requirements of PN-EN 60034-1:2009 standard and the internal inspection plan applicable in ZPRE "JEDLICZE" Sp. z o. o.
We also specialize in modification or revamping repairs of rotating electrical machinery. This service is aimed at substantial improvement of the machinery performance or achieving the features required by Ordering Party. Among other things, we offer:
   • motors’ ventilation systems modernization (to reduce noise),
   • reducing losses and the efficiency coefficient improvement,
   • rotors’ squirrel-cages revamping,
   • bearing units modernization, including bearing system replacement and protection against shaft currents,
   • change of motor specification, including power supply voltage, rated power, rotational speed (RPMs),
   • main insulation and winding insulation improvement,
   • adjusting the insulation system for converted-based power supply,
   • prevention of motor moisture or humidity build-up by installation and assembly of anti-condensation heaters,
   • obsolete terminal boxes replacement with new-generation approved and certified terminal boxes with
     explosion-proof protection.

We also render diagnostic and maintenance services directly at the Ordering Parties’ premises. Our "mobile" crews in service vehicles perform:
   • uninstallation and installation of machines at work station,
   • setting and alignment of repaired machines, using laser equipment,
   • full measurements during test start-up,
   • rolling bearings condition assessment,
   • machinery dynamic condition assessment,
   • winding condition assessment,
   • alignment assessment,
   • transport.

Such wide scope of services we offer guarantees that the repair, overhaul and modernization is comprehensive and Ordering Party can be sure that the machine will work fault-free and reliably at least in the guarantee and warranty period.
