In FIG. 3, the three-phase strip-shaped conductors 1a, 1b, 1c are arranged with a necessary phase interval, and are formed of an insulating material such as resin, FRP or wood. Support member 9 having concave grooves 10 slightly larger than the thickness of 1c provided in the number of phase arrangements
Are arranged on both sides in a direction perpendicular to the phase arrangement direction of the strip-shaped conductors 1a, 1b, 1c, respectively.
b, 1c are fitted into the groove 10.

Further, in order to prevent the strip-shaped conductors 1a, 1b, 1c from dropping or shifting, bolt holes are formed at positions between the opposing surfaces of the two support members 9 to prevent separation therefrom. Connected with bolts 3 and nuts 4, strip-shaped conductor 1
