Cable trays used in China Unicom base stations

China Unicom base stations commonly use aluminum alloy and U steel cable trays, designed for high load-bearing capacity, flexible installation, and compliance with telecommunications standards.Types of Cable TraysAluminum Alloy Cable Trays Aluminum alloy trays are widely used in China Unicom base stations for their lightweight, corrosion resistance, and aesthetic appeal. They are fully open, exposed-frame designs suitable for ceiling-mounted, wall-mounted, and vertical cable routing. These trays support the weight of all cables, provide top-mounted support for equipment, and facilitate maintenance and inspection. Standard widths range from 200mm to 1000mm, with an average load-bearing capacity exceeding 300 kg per meter, making them ideal for dense cabling environments in data centers and base stations (Web result ). U Steel Cable Trays Perforated U steel trays are another common choice, particularly for optical cables, Category 5 cables, and conduit cables. Made from high-quality steel plates with plastic coating or hot-dip galvanization for outdoor use, these trays offer high load-bearing capacity, corrosion resistance, and a compact structure suitable for horizontal, vertical, and multi-layer cable layouts. They allow flexible installation dimensions, adjustable joist spacing (typically 250mm–330mm), and suspension spacing of 1.5m–2m. Load-bearing capacity per meter is also over 300 kg, supporting single, double, or triple-layer configurations (Web result ).Installation and StandardsCable trays in China Unicom base stations are installed along ceilings, walls, shafts, or trenches, with support frames fixed via welding or expansion bolts. Proper spacing between parallel trays is maintained for maintenance and inspection. Both aluminum and steel trays comply with the Ministry of Information Industry standards, ensuring safe and standardized cable management (Web results ).Manufacturers and SourcingChina hosts several leading cable tray manufacturers capable of supplying high-quality trays for telecommunications projects. Notable companies include Shandong JLH Electric Co., Ltd., Koka Cable Tray, Apex Tray, Honest Cable, and KDM Steel. These manufacturers provide ladder trays, perforated trays, wire mesh trays, and custom solutions, ensuring compliance with international standards and suitability for large-scale base station deployments (Web results ).SummaryIn China Unicom base stations, aluminum alloy trays are preferred for their lightweight, aesthetic, and high-load properties, while U steel trays are chosen for durability, corrosion resistance, and multi-layer cable management. Both types support standardized installation, heavy cable loads, and facilitate maintenance, making them essential for modern telecommunications infrastructure.
