The open-hole reinforced cable tray is a new type of energy-saving high-corrosion-resistant light steel tray cable tray, which reduces the material thickness, improves the bearing capacity, reduces the deflection value, and greatly saves the engineering cost. At the same time, the laid cables are completely overhead on the annular rib of the handle, which makes the cable trough ventilated, the heat dissipation effect is greatly increased, and the safety performance of power-on operation is ensured.
