ELECTRIC POWER BUSWAY DUCT IMPROVED THERMAL RADIATION

摘要

An electricity bus duct in which the heat dissipation is improved is provided to change the surface shape of bus bar without punching, lower the temperature of bus bar and increases allowable current under the conventional condition. An electricity bus duct(100) in which the radiation is improved comprises a plural bus bars(101, 102, 103, 104) having long length of section square and enclosure(120). The plural bus bar having long length of section square is electrically insulated. The enclosure surrounds the outside plural bus bars.
