FIELD: electricity.
SUBSTANCE: ladder-type wire tray, equipped with sides of a various height falls within the domain of an electric cable routing. The wire tray (1) comprises a high side and a low side (2, 3) that are joint by a transversal member. The transversal member comprises supporting members that are oriented transverse to the wire tray. The mean cumulative material thickness of the low side overpasses the mean cumulative material thickness of the high side horizontally transverse to the wire tray.
EFFECT: reinforcement of the transversal member that conjoins the sides of the wire tray that comprises the high and low sides, the approximation of the amount of high and low sides deflection under the vertical loading resulting in reduction of the material usage for wire tray with sides of different height manufacturing and in wire tray strength and load-carrying capacity enhancement.
