According to different wiring requirements, the perforated cable tray reducer is divided into two structural forms: concentric reducer and eccentric reducer. Concentric reducer means that the width of both ends shrinks or expands symmetrically, and the transition center line is consistent. It is suitable for standard systems with centrally arranged lines, making the bridge transition neat and beautiful, and effectively maintaining force symmetry. The eccentric reducer means that the width of the bridge at both ends is aligned on the same side, and the transition line is offset. It is suitable for scenes where wiring needs to be done sideways or space is limited. It helps to avoid interference with other equipment or structural parts, and facilitates the fitting arrangement of bridges with walls, columns and other structures. Regardless of the form, the product can achieve a smooth transition from a width difference of 50mm to 400mm, covering most engineering application requirements. The perforated cable tray reducer continues the basic form of the tray bridge, adopts a U-shaped open structure, and has a gradient opening distribution on the bottom and sides. Its opening rate is consistent with the straight bridge section. This opening form not only helps to achieve good ventilation and heat dissipation effects, but also prevents the performance from being reduced due to heat accumulation during cable operation.
