Specifications for Trough-type Fireproof Cable Trays

Fireproof trough-type cable trays are fully enclosed systems designed to protect cables from fire, mechanical damage, moisture, and electromagnetic interference, with fire resistance up to 90 minutes.Key FeaturesEnclosed Trough Design: The tray is fully enclosed with a matching cover, providing complete protection for cables against dust, water vapor, falling debris, chemical corrosion, and electromagnetic interference, making it ideal for sensitive control, communication, and low-voltage signal cables . Materials: Commonly manufactured from high-quality steel (Q235), stainless steel, or aluminum alloy, often combined with fire-retardant coatings and advanced surface treatments for durability and corrosion resistance . Fire Resistance: Fireproof trough-type trays are engineered to maintain circuit integrity during fire incidents, with fire endurance ratings typically ranging from 45 minutes (F3) to 90 minutes, depending on the standard and application . They comply with international and national fire safety standards, such as GB 29415-2013 in China . Dimensions: Standard widths range from 50 mm to 1200 mm, with customizable heights and lengths. Edge structures can include 45-degree, 90-degree, or return edges to enhance safety and structural performance . Modular designs allow for straight sections, elbows, tees, and reducers for flexible routing . Customization: Trays can be tailored in material, dimensions, color, surface treatment, and fireproof coating, supporting OEM and ODM services for complex projects . Fireproof coatings are typically eco-friendly, non-toxic, and smoke-suppressant . Installation: Supports overhead, wall-mounted, vertical shaft, and suspended applications. Removable covers facilitate inspection and future expansion without major reconstruction. Standardized brackets and fastening systems reduce installation time and labor costs . Applications: Widely used in power plants, data centers, hospitals, tunnels, underground garages, shopping malls, transportation systems, petrochemical facilities, and high-rise buildings where fire safety and cable protection are critical .SummaryFireproof trough-type cable trays provide a robust, fire-resistant, and fully enclosed solution for critical cable management. They combine mechanical protection, fire endurance, and electromagnetic shielding with flexible installation and customization options, making them suitable for both industrial and commercial environments where safety and reliability are paramount .
