Transformer Rewinding
Our transformer rewinding process involves complete coil replacement using premium-grade enameled copper, reinforced with Class-H insulation and thermally upgraded paper for maximum thermal endurance. The core is carefully realigned to restore its original magnetic properties, and we apply VPI (Vacuum Pressure Impregnation) to seal and strengthen the windings against moisture, vibration, and mechanical stress. Comprehensive electrical testing — including impulse voltage, temperature rise, and partial discharge — ensures every rewound transformer meets or exceeds OEM standards. This approach not only restores performance but often enhances it, enabling transformers to handle greater load variations and operate with improved efficiency.
- ⚡ High-grade copper conductors for superior conductivity
- ⚡ Class-H insulation ensuring high thermal stability
- ⚡ VPI process for enhanced mechanical strength

Transformer Repair
We deliver rapid yet thorough transformer repairs that minimize downtime and restore full operational capacity. Our process begins with detailed diagnostics, including infrared thermography and winding resistance tests, to identify underlying issues. Whether it’s a faulty bushing, degraded insulation, or tap changer malfunction, we implement targeted solutions that address root causes, not just symptoms. This ensures safe, reliable operation without the expense of a complete replacement. By integrating predictive maintenance schedules post-repair, we extend your transformer's working life and reduce the likelihood of recurrent faults.

Transformer Refurbishment
Our refurbishment services breathe new life into transformers that have aged but still possess solid structural integrity. We introduce hybrid insulation with aramid paper for superior dielectric strength, apply fresh coil varnishing for added protection, and perform vacuum drying to eliminate moisture. The refurbishment process also includes detailed visual inspection, ultrasonic cleaning to remove contaminants, and high-voltage withstand tests to validate performance. The outcome is a transformer that operates as reliably as a new unit while meeting current industry safety and efficiency benchmarks.
- 🔄 Hybrid insulation for extended lifespan
- 🔄 Moisture removal via advanced vacuum drying
- 🔄 Full compliance with modern performance standards
- 🔄 Enhanced thermal performance and overload capacity

Transformer Retrofitting
Retrofitting is a strategic way to modernize existing transformers without replacing them entirely. We upgrade core components, insulation systems, and cooling mechanisms to meet evolving operational demands. Smart monitoring systems, fault detection relays, and advanced protection circuits are integrated to improve reliability and enable predictive maintenance. Retrofitting ensures compliance with current grid codes, reduces energy losses, and prepares transformers for modern load conditions — all while being cost-efficient and environmentally sustainable.

Transformer Longevity & Reliability Enhancement
Our longevity enhancement programs are designed to proactively maintain and upgrade transformers, ensuring reliable performance for decades. Using advanced rewinding techniques, insulation replacements, and critical component upgrades, we restore transformers to near-original condition while often improving their operational efficiency. We also implement vibration analysis, oil sampling, and thermal imaging as part of ongoing condition monitoring, helping to predict potential failures before they occur. This approach prevents unexpected outages, reduces operational risk, and maximizes return on investment.
