Bus Duct

The bus bar system forms the main power distribution within an assembly and is one of the critical elements determining the assembly’s operational reliability and safety. The bus bar system is designed to withstand the mechanical and thermal stress existing during normal service as well as under fault conditions. The main bus bar can be arranged at the top, bottom or at any module in between in the enclosure.

The bus bar support insulators are used a high grade SMC/DMC/FRP which can withstand all the mechanical and thermal stresses involved. All systems up to 8800 A can be assembled as standard. Multiple Bus bar per phase arrangement is used. This allows connections and extensions to be made with either Copper or Aluminium bus bars. For higher ratings interleaved bus bar arrangements are also offered for lesser temperature rise and efficiency in conducting current.
