Ladder cable troughs are manufactured by pulling the side panels using a molding machine, which enhances the overall bending resistance of the trough. The side panels and bottom plates are reinforced with extra strength, resulting in a beautiful appearance and high load-bearing capacity. The ladder-style trough is a new type of product improved based on domestic and international information and similar products. It has the advantages of light weight, low cost, unique design, convenient installation, good heat dissipation and ventilation. It is suitable for laying large-diameter cables and is particularly suitable for laying high and low-voltage power cables.
