Since 1990, KROS Electric Co., Ltd. has established itself as a pioneer in electrical transformer design, manufacturing, and international power infrastructure support. Founded under the leadership of Mr. I. Narayana Rao—a industry veteran with over four decades of hands-on expertise in electrical machine design and high-voltage testing—our organization delivers uncompromising power reliability to B2B buyers worldwide.
Operating state-of-the-art manufacturing facilities, our multidisciplinary teams integrate advanced electromagnetic design, premium insulation material science, and rigorous quality assurance protocols to engineer custom transformers optimized for rugged grid conditions and tropicalized environments.
KROS Electric Co., Ltd. is a BIS-certified and ISO 9001:2015 compliant manufacturer. Our complete equipment lineup undergoes comprehensive Type Testing at globally accredited independent laboratories including CPRI (Central Power Research Institute) and ERDA (Electrical Research and Development Association). Every unit is built to withstand thermal stress, short-circuit forces, and harsh industrial load cycles.
Our high-capacity manufacturing centers are equipped with automated winding machinery, vacuum drying chambers, and integrated high-voltage test bays engineered for international project requirements.
Our primary production hub focuses on precision-wound distribution transformers, core assembly, and oil impregnation systems. Unit-I houses core shearing equipment and modern drying ovens ensuring low losses and optimal energy performance.
Designed for heavy power transformers, solar inverter-duty units, and flame-retardant dry-type equipment up to 10 MVA. Unit-II features overhead heavy-duty cranes, automated oil handling plants, and advanced testing bays.
The global power transmission sector demands more than legacy steel and copper windings. International procurement teams require maximum efficiency, climate resistance, reduced operating losses, and seamless integration with renewable energy microgrids. KROS Electric Co., Ltd. combines engineered resilience with smart monitoring options to deliver long-term operational stability.
