345kV
Since its establishment, SEMYUNG has been striving for the business of fittings for power along with the national industrial development.
We have contributed greatly to the development of Korean infrastructure industry by localizing fittings for 345kV transmission lines
which had depended entirely on imports due to a short history of the electric power industry, resulting in the effect
of import substitution and accumulation of technology.
