The supply of electricity required for national industrial facilities is a nationally important business. Since a lot of power loss occurs during power transmission and distribution, recently the voltage has been raised to high or ultra-high voltage for transmission and distribution. Accordingly, high-precision transmission and distribution materials are essential. Hwasung Tech possesses core technologies in producing and handling products that require advanced technology. Until now, the maximum voltage was 345,000 V, but in order to reduce losses and facility maintenance costs, the maximum voltage has been raised to 765,000 V, and some of it is under construction. As a leader in the production of ultra-high voltage hardware that requires special materials and technologies, differentiating it from the products we have been supplying, we can secure competitiveness.​ There are several manufacturers of hardware up to 345,000V, but only Hwasung Tech handles hardware up to 765,000V of ultra-high voltage. ​ The 765,000V hardware that we manufacture is a cutting-edge material essential for ultra-high voltage transmission, and is a material that can achieve the best insulation effect. We are confident that the advancement of material technology in other fields and the improvement of the quality of insulating materials that can withstand ultra-high voltage will bring innovation to the electrical industry.
