Assembly Bay
Power Transformer Final Assembly
Inspection of heavy oil-immersed power transformer complete with external radiator banks, conservator tank, and HV bushings prior to oil-filling.
Engineering Precision & World-Class Manufacturing Facilities
Since 1991, Kokila Electricals has maintained strict compliance with ISO 9001 quality management systems and international electrical standards (IEC 60076, IS 2026, ANSI/IEEE). Our modern production floor in Vijapur, Gujarat, spans high-grade magnetic core assembly, heavy-duty electrolytic copper coil winding, vacuum drying chambers, automated oil purification plants, and fully integrated high-voltage routine & type testing bays. Below is a real-world visual inspection of our heavy industrial transformers and factory floor activities prepared for international utility buyers and industrial EPC partners.
Manufacturing
Heavy Fabrication & Tank Fitting
Precision-welded leak-proof corrugated and plate tanks designed to withstand vacuum pressure and harsh outdoor industrial environments.
Heavy Duty
Industrial Furnace Transformer
Robust short-circuit resilient coil construction designed for electric arc and steel induction furnace duty with extreme mechanical stress tolerance.
Quality Assurance
HV Testing & Routine Verification
Every transformer undergoes complete routine tests (ratio, vector group, winding resistance, dielectric insulation, and loss measurements) in our lab.
Steel & Metallurgy
Electric Arc Furnace Unit
Custom secondary voltage tap changer configuration engineered for continuous ultra-high current operation in metal processing plants.
Grid Distribution
Three-Phase Distribution Units
Low-loss CRGO core distribution transformers manufactured for municipal power grids, commercial complexes, and industrial distribution lines.
