Generally, in a factory house, large and small diameter power cables are installed along the ceiling, floor or wall for the supply of power to each household. Especially, the power cable that is installed along the ceiling is installed in a tidy state using a cable tray, And facilitates maintenance and inspection.

1 and 2, the conventional cable tray structure for a power distribution has a structure in which a support bar 14 is fixed to a lower end of a hanger bolt 11 or 12 installed on a ceiling by using nuts 13a and 13b, And the side rails 16 and 17 connected by the rungs 15 are fixed on the support bars 14 in a state of being fixed.

The power cable 18 is installed at a constant interval in the constructed cable tray 10 and then the power cable 18 is connected to the runway 15 using the coupling band 19 so that the power cable 18 can not move. Respectively.

However, since the rung 15 provided on the cable tray 10 is orthogonal to the power cable 18, the power cable 18 and the rung 15 are not in contact with each other when the coupling band 19 is fixed to the rung 15. [ There is a problem that the power cable 18 can not be formed in a straight line and is bent by being pushed in one direction by the coupling band 19. In this case,

Further, conventionally, since the coupling band 19 is fixed in the oblique direction, the coupling force of the coupling band 19 is concentrated on the local portion of the power cable 18, and the insulation coating of the power cable 18 is easily damaged .

Since the rung 15 is conventionally straight and there is no part for holding the binding band 19 from moving when the binding band 19 is fastened, the fastening band 19 is arranged in the longitudinal direction of the rung 15 The distance between the power cables 18 becomes narrower or wider as the power cable 18 moves along the cable.
