How to connect Spanish cable trays

Connecting Spanish cable trays involves aligning sections, using straight connectors or joint plates, and securing them with bolts and nuts according to manufacturer guidelines.Step-by-Step Connection Process1. Plan and Prepare the Route Before connecting trays, mark the cable tray route considering clearance, load capacity, and cable separation requirements. Ensure the path is level and supports are spaced appropriately, typically 1.5 to 3 meters apart depending on tray type and load . 2. Select the Correct Connector For straight connections, use a straight connector (e.g., RLVL connector for tray heights 85–110 mm). For wider trays (≥400 mm), a joint plate is recommended to prevent transverse bending . Smaller trays (≤300 mm) may not require a joint plate. 3. Align and Insert Insert the straight connector into the inside of the tray rail. Ensure both tray sections are aligned straight and level. Misalignment can cause sagging or stress on the tray . 4. Secure with Bolts and Nuts Fasten the connector using FRS M6 truss-head bolts and combination nuts. Tighten securely but avoid over-torquing, which could damage the tray or coating . 5. Handle Bends and Fittings For 45° or 90° bends, T-pieces, or crossovers, use pre-mounted turn buckles if available. If not, secure the fitting with additional support brackets. Ensure the bend radius meets cable specifications to prevent damage . 6. Check Stability and Support After connecting, verify that the tray is level and properly supported. Use additional brackets or hangers if necessary, especially for long runs or heavy cable loads . 7. Optional Covers If using covers, mount them according to the manufacturer's instructions. Covers may be held by pre-mounted turn buckles or supported by the tray path .Tips for Safe InstallationAlways wear protective equipment when cutting or handling trays.Re-drill connector perforations if unperforated trays are cut.Maintain minimum bend radius for cables exiting the tray to prevent stress or insulation damage .Follow local electrical codes and standards (e.g., IEC 61537) for low-voltage cable tray systems . By following these steps, Spanish cable trays can be securely connected, ensuring a safe, organized, and durable cable management system.
