Korean Tray-type Cable Tray Installation

Korean-style cable trays are installed using adjustable supports, one-touch clamps, and modular components to ensure efficient, safe, and organized cable management.Key Features of Korean Cable TraysKorean cable trays often feature one-touch clamp fastening, allowing easy installation, adjustment, or removal without additional tools. Supports can be installed fastener-free using hooks, and height adjustments typically range from 80 mm to 200 mm. Cable dividers are used to organize multiple pathways and prevent tangling, while perforated or solid bottom covers provide protection for cables in straight sections and fittings. Materials like POSCO PosMAC offer superior corrosion resistance, up to 5–10 times more than standard hot-dip galvanized steel, making them suitable for industrial and commercial applications .Installation StepsSelect the Tray Type: Choose from ladder, perforated, solid bottom, wire mesh, or channel trays based on cable type, load, and environmental conditions .Mount Supports: For wall installations, use RVK wall supports or mounting rails. Ceiling or floor installations may use HK1, HK2, or TP2 supports. Supports are positioned inside the tray for a clean appearance .Attach the Tray: Lift the edge of the tray onto the support tip and press the opposite edge into place. One-touch clamps secure the tray without additional fasteners .Install Dividers and Covers: Place cable dividers to separate different cable groups. Attach perforated or solid covers to protect cables from dust, mechanical damage, or electromagnetic interference .Adjust Height and Alignment: Ensure trays are level and maintain proper spacing between supports. Adjust height as needed using the built-in adjustment range .Routing and Securing Cables: Lay cables in the tray, maintaining minimum bend radii and proper spacing. Use additional clamps or ties if necessary to prevent sagging or movement .Best PracticesMaintain consistent rung spacing (150–230 mm) for ladder or mesh trays to support cables evenly .Use corrosion-resistant materials in humid or industrial environments.Plan cable pathways to minimize bends and intersections, using T-pieces, crossovers, or reductions where necessary .Regularly inspect trays for mechanical integrity and cable organization to ensure long-term reliability. Korean-style cable tray systems combine modular design, ease of installation, and high durability, making them ideal for complex electrical installations in commercial and industrial settings .
