PROBLEM TO BE SOLVED: To provide an insulated bus duct connection part that allows large capacity branching, and that can be manufactured easily and at low cost. SOLUTION: The insulated bus duct connection part comprises: main conductors (11a, 12a), (11b, 12b), (11c, 12c) of the same polar phase whose ends are laid over each other; insulating separators 15 each provided between (11a, 12a) and (11b, 12b), (11b, 12b) and (11c, 12c) of different phase conductors and between the outermost main conductors (11a, 12a) and (11c, 12c) and duct side plates 14a, 14b; and fastening means 20 that totally fasten each insulating separator 15, all the main conductors 11a to 11c, 12a to 12c, and each duct side plate 14. On each overlaid surface of the main conductors (11a, 12a), (11b, 12b), (11c, 12c) of the same polar phase, connection conductors 13 of a flat plate shape, whose width is wider than that of the main conductors 11a to 11c, 12a to 12c, are provided protrusively out of the one end or both ends of the widthwise direction of the main conductors 11a to 11c, 12a to 12c. Each of the connection conductor protruding parts 23a, 23b that are protruding out of the main conductors 11a, to 11c, 12a to 12c is formed into a plug-in branch part. COPYRIGHT: (C)2004,JPO
