Transformer rewinding is the process of replacing the damaged or failed copper windings (coils) inside a transformer. This is a crucial service performed when a transformer fails due to issues like a short circuit, insulation breakdown, or prolonged overheating. The process begins by carefully dismantling the transformer to remove the old, damaged coils. The core is then thoroughly cleaned, and new, high-quality insulation is applied. Finally, new windings are meticulously installed according to the transformer's original specifications. This service is a cost-effective alternative to purchasing a new transformer, as it restores the unit's functionality and extends its operational lifespan, ensuring the continued, reliable distribution of power.
