Sanil Electric

Sanil Electric makes industrial transformers, devices that step electrical voltage up or down so that power generated at a plant can be safely delivered to factories, businesses, and homes.

It focuses on distribution transformers, which sit at the final stage of the power grid before electricity reaches end users, as well as specialised transformers built for inverters, renewable-energy systems, and energy-storage equipment. Listed on KOSPI, Korea's main stock exchange, the company derives the overwhelming majority of its revenue from exports, with the United States accounting for the largest share of those international shipments.
