Trough-type polyurethane cable trays are enclosed cable laying devices made of high-strength polyurethane composite materials, offering excellent anti-corrosion, flame-retardant, and insulation properties. Compared to traditional metal cable trays, polyurethane trays are lightweight, high-strength, and highly weather-resistant, making them particularly suitable for humid, highly corrosive, and high-insulation-demand environments such as chemical plants, power plants, offshore platforms, tunnels, and underground utility tunnels. Their enclosed design effectively prevents dust, rainwater, and acidic/alkaline gases from corroding cables, extending cable service life while reducing electromagnetic interference and ensuring signal stability. The tray surface is treated with anti-UV and anti-static coatings, ensuring long-term resistance to aging, cracking, or deformation. It operates stably in temperatures ranging from -40℃ to 120℃, meeting cable protection requirements in harsh environments.

Common specifications of trough-type polyurethane cable trays include widths of 50-600mm, heights of 50-200mm, and thicknesses of 2~5mm, with customizable dimensions based on project requirements. They offer strong load-bearing capacity, supporting weights of 50kg~200kg, and possess excellent insulation, tensile strength, and flexural strength, effectively preventing electric leakage and electric shock accidents.

Additionally, these trays achieve a flame retardancy rating of UL94 V-0, meaning they are difficult to ignite and do not produce harmful smoke when exposed to fire, complying with various safety standards. Installation is flexible, with options such as wall-mounted, ceiling-mounted, or bracket-fixed methods, and maintenance is convenient without the need for additional coating treatments, resulting in low long-term costs.

Overall, trough-type polyurethane cable trays outperform traditional metal trays in terms of protection, durability, and ease of installation, making them an ideal choice for modern industrial and power systems.
