PURPOSE: A cable tray for an apartment building power distribution is provided to prevent damage to an insulation sheath by coupling a binding band in a direction perpendicular to a power cable. CONSTITUTION: A bundle jaw is formed along both edges of rungs in the form of a stair. A retaining jaw(31a,32a) prevents the separation of a binding band. Rectangular connection parts(33,34) are formed on both ends of the rung. Fitting projections(53,54) are formed on a combination part of a side rail. The side rail is in contact with the rectangular connection part of the rung. |
