HICOs first successful development of 154kV extra high-voltage (EHV) transformers in 1969 hastened the coming of age of the high-voltage grid system in Korea. The subsequent development of 345kV transformers along with 362kV EHV GCB & GIS (Gas Insulated Switchgear) in 1978 demonstrated HICOs highly advanced technological expertise in electrical engineering.
In January of 1999, HICO made big strides in the field of electrical engineering by designing 765kV ultra high-voltage (UHV) transformers, also called a highway of power supply. As a result of ceaseless R&D activities, HICO succeeded in developing 800kV GIS in February 1999.The continued technological progress has enabled HICO to produce a wide range of products, including electrical motors, gear reducers, electric panels and instrumentation systems. The Company also implemented several turnkey projects, making full use of its comprehensive engineering capacity in heavy electrical equipment and industrial achinery.
HICO is proud of its superior technology in design, manufacture, and follow-up services, all of which are supported by cutting-edge automation facilities. HICO has set up a total quality management system to ensure the highest level of customer satisfaction. In 1993, HICO received the ISO 9001 Certificate, solidifying its position as Korea s largest manufacturer of integrated heavy electrical equipment.The Hyosung Way is comprised of the mission (the reason for our company's being), core values that serve as the basis of our thinking and actions, and the principle which is the basic principle for our actions.
