Initiating operations from a specialized production unit in 1991, Kokila Electricals has developed into an ISO 9001 certified transformer manufacturer capable of engineering customized power, furnace, distribution, and LST transformers up to high kVA and MVA capacities. Our state-of-the-art manufacturing plant in Gujarat, India, strictly complies with relevant IEC 60076, IS, and international safety standards.
Over the past 30+ years, our continuous investment in core-winding technologies, vacuum drying systems, and full-fledged high-voltage testing infrastructure has positioned us as a trusted partner for public power utilities, EPC contractors, steel manufacturers, and chemical conglomerates globally.
Our engineering team has executed complex transformer manufacturing, ratio conversion, and heavy-duty overhauling contracts for global leaders.
Engineered and commissioned a high-capacity 66 kV class 10/12.5 MVA power transformer equipped with On-Load Tap Changers (OLTC) for Videocon Industries Ltd. (Chavaj Plant), passing stringent field validation and short-circuit endurance trials.
Custom-fabricated an 11.5 MVA 11/11.5 kV step-down transformer featuring automatic OLTC for NCPL Narmadanagar (Bharuch), successfully verified by full factory acceptance testing (FAT) under third-party inspection.
Designed and supplied a high-precision 1.25 MVA transformer with OLTC integration to Schott Glass Ltd., meeting critical continuous thermal withstand requirements and zero-downtime tolerance standards.
Served as a long-term key OEM partner for wind energy and grid infrastructure leader Suzlon Infrastructure Services Ltd., manufacturing heavy-duty 11kV, 22kV, and 33kV class distribution and step-up transformers.
Successfully designed and integrated a custom 1600 Ampere Series Reactor (11 kV / 11 kV) for Reliance Industries Ltd. (Textile Division), providing precision power factor correction and harmonic stabilization.
Maintained multi-decade vendor approvals and supply agreements with major Indian state power utilities, including GETCO, UGVCL, GSECL, and GMDC, delivering thousands of reliable distribution transformers.
