When issues like moisture ingress, contamination, or electrical faults cause a transformer’s copper coil windings to fail, many components like the core, tank, and bushings often remain in good condition. Rather than scrapping the entire transformer, rewinding the damaged coils is a reliable, cost-effective way to restore function quickly.
Electric Power Systems leverages our in-house expertise in reconditioning industrial transformers to maximize longevity at commercial facilities, utilities, and industrial plants nationwide. Our skilled technicians have rewound thousands of units from small control transformers up to large 15 kV power transformers using precision techniques perfected over decades.
The transformer coil rewind process begins by fully inspecting your transformer to precisely determine the faulty winding’s original specifications. We establish the precise wire gauge, winding pattern, voltage class, tap configurations, and any specialty features needed to match OEM electrical performance. Our engineers consider design upgrades to mitigate the original failure mode as well.
We strategically source high-quality UL-rated winding wire along with insulating materials that withstand elevated temperatures and test voltages. Installing the newly engineered winding onto the transformer’s original core and securing intricate connections requires considerable skill. Our specialized winding machines expertly recreate winding patterns for optimal magnetic properties before we permanently cast leads within the coil structure. Finally, we reassemble the transformer within the original tank and restore any corroded bushings or gauges.
Following transformer coil rewind completion, each transformer undergoes thorough final safety checks and operational testing. Only after confirming the unit meets OEM specifications do we return transformers to service. Rewinding only faulted coils rather than full unit replacement saves sizable capital and significantly cuts downtime.
