Perforated cable tray cross adopts a four-way equal-width cross-connection design, and each interface has the same width, ensuring that the cables can transition freely between different directions. At the same time, the wiring is smooth and the tension is balanced, and there will be no jamming or accumulation due to width differences. The bottom plate of this product is a grid perforated design, and the perforation rate is consistent with the straight-through section, which has excellent heat dissipation performance and weight control capabilities. The perforated structure is arranged in a regular array, which helps to dissipate heat and cool down the cable during operation. Perforated cable tray cross shows high scalability in terms of functionality, especially in terms of X/Y axial synchronous expansion. The product design takes into account the cable wiring requirements of multi-point extension, allowing users to extend the line in any direction without repeatedly adjusting the main bridge structure. Only quick docking at the four-way interface can achieve synchronous expansion of the system. In order to enhance the structural strength and long-term bearing capacity, this four-way has added a reinforcing rib design in the center. The reinforcing ribs are distributed in a cross and extend symmetrically with the four branches, which improves the compression and bending resistance of the middle node from the perspective of structural mechanics.
