Mangal Electrical Industries Ltd. Enhances Transformer Core Reliability Through Precision Manufacturing and Advanced Testing

Mangal Electrical Industries Ltd. develops transformer components through precise engineering work and advanced manufacturing processes that support the growing global demand for power infrastructure. The company delivers products that exceed expectations for reliability and operational longevity, thus establishing new industry standards that utilities, EPC contractors and transformer OEMs must follow.

Mangal Electrical Industries Ltd. is one of India’s leading manufacturers of CRGO processing and transformer core components, headquartered in Jaipur and serving customers across the country while steadily expanding its global footprint. The company manufactures precision transformer components using controlled core cutting and stacking processes, maintaining burr levels below 10 microns to ensure magnetic integrity and reduced core losses. Production is carried out in a Class 9 dust-controlled facility to prevent contamination of lamination surfaces and preserve insulation coating performance. The need for reliable electrical equipment suppliers has reached its peak because of growing global power demands and expanding grid systems.

Buyers in transmission and distribution networks now prefer to assess products based on their complete lifecycle performance instead of using price as their only criterion. The transformer fleet studies show that no-load losses contribute a significant share to the total energy costs that transformers incur throughout their operational life. Manufacturers now need to implement advanced manufacturing methods that enable them to achieve both repeatable results and consistent outcomes through engineering standards.

Mangal Electrical Industries Ltd. produces various products, which include CRGO slit coils and laminations, wound cores and core assemblies, amorphous cores, core coil assemblies, and oil-immersed circuit breakers (ICBs). The manufacturing and testing process spans from incoming CRGO material inspection to final dimensional and magnetic verification, minimizing performance variability and ensuring long-term reliability.

The company operates an advanced Brockhaus electrical steel testing laboratory compliant with IEC and ASTM standards. Testing includes Epstein frame testing and Single Sheet Tester (SST) analysis to verify core loss, permeability, and magnetic performance before dispatch, ensuring consistent and traceable quality for transformer OEMs. The company is certified under ISO 9001 (Quality Management), ISO 14001 (Environmental Management), and ISO 45001 (Occupational Health & Safety) certifications, reinforcing its commitment to structured processes, environmental responsibility, and workplace safety.

Mangal Electrical Industries Ltd. also holds PGCIL approval up to the 765 kV class, which means that Power Grid Corporation of India Limited has certified the company to meet all required technical standards for extra-high voltage EHV transformer applications.

Mangal Electrical Industries Ltd. uses high-quality materials together with controlled manufacturing processes to establish new standards for component quality, which enables the company to function as a reliable electrical manufacturing company for transformer producers throughout the world.
