After setting a substation in Nampho City as a model unit and the transmission line from the Pukchang Thermal Power Complex to the substation as a model line, the ministry has taken measures to turn it into a model unit in a short span of time while reinforcing its technical forces and supplying necessary equipment and materials on a preferential basis.

The Transformer Substation Management Bureau is pushing ahead with the work to set up efficient lightening rods made in connection with Kim Chaek University of Technology on transmission steel towers across the country.

The transformer substation units across the country are systematically improving the security of power supply.
