Leading Indian Transformer Manufacturer Serving Global Markets
Established in 1991, Kokila Electricals has grown into one of India's premier engineering firms specializing in the custom design, manufacturing, and servicing of high-reliability power, distribution, furnace, dry-type, and line stabilizer (LST) transformers.
Headquartered in the industrial hub of Vijapur, Gujarat, our operational footprint encompasses four specialized industrial units. Built on decades of technical research and heavy electrical engineering experience, we deliver robust energy distribution equipment tailored to international utility, EPC, steel, chemical, oil & gas, and heavy manufacturing specifications.
Engineering Excellence & Manufacturing Capability
Our state-of-the-art facilities integrate advanced winding equipment, vacuum pressure impregnation, and computerized testing laboratories to guarantee optimal thermal and mechanical performance.
In-House CAD Design
Headed by our Director of Electrical Engineering, our design department utilizes proprietary calculation algorithms and 3D modeling software to optimize magnetic flux, short-circuit withstand capabilities, and thermal dissipation paths for every custom order.
Dedicated Production Units
We maintain separate, fully equipped plants for manufacturing new transformers up to 22 MVA and repairing/upgrading existing industrial units up to 100 MVA, ensuring streamlined workflow, clean assembly environments, and strict quality separation.
Rigorous Quality Assurance
Adhering to ISO 9001 guidelines, every raw material—from high-grade CRGO laminations to electrolyte copper conductors and transformer oil—undergoes strict supplier validation and incoming quality inspection before entering production.
Full Lifecycle Support: Production & Overhaul
Beyond new manufacturing, Kokila Electricals offers worldwide technical expertise for overhaul, retrofitting, and high-capacity transformer repair services.
Manufacturing Unit (Up to 22 MVA)
Equipped with automatic coil winding machines, vacuum drying ovens, oil filtration plants, and overhead cranes. Designed for manufacturing oil-filled power, three-phase distribution, electric arc furnace, and cast resin dry-type transformers built to stringent international utility standards.
Overhaul & Repair Unit (Up to 100 MVA)
Our dedicated repair facility provides emergency rewinding, core inspection, insulation drying, tank fabrication, and complete electrical re-testing for heavy industrial power transformers up to 100 MVA, minimizing critical downtime for plant operators.
