Hyosung - Extra-High-Voltage Transformers for Global Power Grids
Hyosung Heavy Industries is a recognized leader in the manufacturing and distribution of extra-high-voltage transformers, playing a crucial role in global power grid enhancement. Since pioneering Korea's first 154 kV transformer in 1969, the company has evolved its technological capabilities to include 345 kV and 765 kV transformers, demonstrating a commitment to innovation and excellence. With a sprawling production facility in Changwon, Hyosung has produced over 7,500 transformers, catering to more than 70 countries. The company's transformer range includes eco-friendly ester oil, gas-insulated, and phase-shifters, tailored to industries like railroads and data centers. Complemented by a global production network, Hyosung adheres to international standards such as IEC, ANSI, and ISO certifications, ensuring high-quality products. Their solutions span power plants, substations, and specialized applications, underscoring their sophisticated, robust, and green technologies aimed at facilitating seamless project execution.Since developing Korea's first 154 kV extra-high-voltage transformer in 1969, Hyosung Heavy Industries has been at the forefront of extra-high-voltage transformer technology, developing Korea's first 345 kV and 765 kV transformers in 1978 and 1992, respectively.
Hyosung Heavy Industries, which manufactures a variety of transformers with a maximum voltage of 765 kV and a maximum capacity of 1,500 MVA, offers both inner and outer-type products, allowing customers to choose from a vast selection.
As a world-class transformer brand that provides solutions for customers in over 70 countries by designing, manufacturing, and testing in accordance with each country's standards, we have manufactured more than 7,500 extra-high-voltage transformers at the Changwon Plant alone. Since the 1970s, when we began exporting transformers, our quality and service have been recognized by customers worldwide. Furthermore, our global production network, which includes local production bases in the US and China, is contributing to the development of global power grids.
We manufacture transformers for special applications, such as eco-friendly ester oil transformers, gas-insulated transformers, mobile transformers, phase-shifting transformers, and STATCOM transformers. We also provide products for diverse industries including railroads, electric furnaces, and data centers.
