Transformers are the backbone of any power system—whether it’s an industrial plant, a commercial building, or a manufacturing unit. Over time, these transformers begin to show signs of ageing. Efficiency drops, overheating becomes common, and the risk of sudden failure increases. This is where power transformer rewinding services become essential.
Instead of purchasing a new transformer—an expensive and time-consuming decision—rewinding offers a smart, economical, and highly effective solution. And when it comes to rewinding old or faulty transformers, Asea Power Electricals has become one of the most trusted names in the industry.
With years of hands-on experience, technical expertise, and a commitment to precision engineering, Asea Power Electricals helps revive ageing transformers and restore them to peak performance.
Understanding the Importance of Transformer Rewinding
Transformers, like any electrical equipment, undergo stress over years of service. Dust, overload, heat, environmental exposure, and insulation damage all contribute to wear and tear. At some point, rewinding becomes essential to restore efficiency and prevent breakdowns.
Transformer rewinding helps in:
- Improving voltage regulation
- Reducing power loss
- Enhancing operational safety
- Extending equipment lifespan
- Minimizing unplanned downtime
By choosing a professional rewinding service, industries can save significant costs while maintaining high-quality power delivery.
How Asea Power Electricals Revives Ageing Transformers
Asea Power Electricals follows a careful, methodical, and expert-driven approach to bring old transformers back to life. Our goal is not just to repair but to enhance transformer performance and reliability.
1. Detailed Inspection and Problem Identification
Every rewinding project begins with a deep analysis of the transformer. Asea Power Electricals checks:
- Winding damage
- Insulation condition
- Core wear
- Oil contamination
- Overheating patterns
- Faulty connections
This helps them create a clear rewinding plan with transparent steps and timelines.
2. Precision Coil Rewinding
Asea Power Electricals uses high-quality copper conductors, modern winding machines, and standardized techniques to rewind the coils. The focus is always on improving efficiency and adhering to electrical standards.
3. Improved Insulation for Long-Term Safety
Insulation plays a major role in preventing failures. Asea Power Electricals uses high-grade insulation materials to ensure longevity, durability, and safety—even under heavy load conditions.
4. Core Repair and Enhancement
Sometimes, the transformer core needs attention too. Our technicians check for:
- Lamination damage
- Rust formation
- Alignment issues
Fixing the core helps restore transformer efficiency.
5. Reassembly, Testing & Final Quality Check
Before returning the transformer to the client, Asea Power Electricals conducts:
- Ratio test
- Load test
- Temperature rise test
- Insulation resistance test
- No-load and full-load tests
Only after everything meets industry standards, the transformer is cleared for delivery.
Why Rewinding Is Better Than Replacing
Businesses often assume that replacing a transformer is the only way to solve power issues. But in reality, rewinding offers several benefits:
- Cost-efficient: Rewinding costs far less than buying a brand-new transformer.
- Faster turnaround: Replacement may take weeks, whereas rewinding is quicker.
- Eco-friendly: Reusing equipment reduces industrial waste.
- Perfect for older systems: Many old transformers are built with superior materials; rewinding restores our original strength.
When done professionally, rewinding can add 10–15 more years of life to an ageing transformer.
