  • Pro IPB(Isolated Phase Bus)
    Hyosung Heavy Industries is the only company with IPB design / manufacturing technology in Korea. Since 1985, Hyosung has been supplying products with a maximum rated current of 43,000A to various domestic and overseas Power generation companies such as Korea Hydro & Nuclear Power Co., Ltd. By minimizing the number of nodes, the installation time was shortened, and applied the sliding type with consideration of conductor expansion.

    Features and Benefits

    • Reduce installation time by reducing the number of nodes Hyosung has a variety of current capacity products.
      Minimizing the number of nodes and designing the support allowance tolerance can shorten installation time.
    • Structural design with weather resistance in mind IPB installation conditions ensure product reliability through structural analysis programs that can overcome natural conditions such as strong winds, salinity, and earthquakes.
      Minimizes installation errors with 3D scanning method to ensure installation reliability
