Cable tray 120 angle

A 120° cable tray angle is a specialized fitting that allows the cable tray to change direction by 120 degrees, typically used in horizontal or vertical routing of cables.OverviewA 120° angle connector for cable trays is designed to redirect cable runs smoothly while maintaining structural integrity and cable support. These fittings are commonly used in industrial, commercial, and data center installations where cable pathways need to navigate around obstacles or follow architectural layouts. They are available in various materials such as galvanized steel, stainless steel, or plastic, depending on environmental conditions and load requirements .Design and CompatibilityAdjustable vs Fixed Angles: Some connectors, like the WKV 35, are designed for 90° bends but can be adjusted on-site to angles such as 45° or potentially 120° with proper alignment .Side Height and Width: Standard side heights (e.g., 35mm) and tray widths (100–400mm) are common, and the fitting must match the tray dimensions for secure installation .Perforated vs Solid Trays: Perforated trays allow ventilation and heat dissipation, which is important for high-current or sensitive cables .Installation ConsiderationsFastening: Angle connectors are typically shipped unmounted and require bolts, nuts, or other fastening materials to secure them to the tray .Support Spacing: According to NEMA VE-2 standards, supports should be installed within 24 inches on both sides of the fitting to maintain stability .Horizontal and Vertical Use: 120° angles can be used in horizontal planes or vertical transitions, depending on the system design. Vertical bends are often pushed over the tray end and screwed tight .Standards and ComplianceCable tray systems, including angle fittings, must comply with DIN EN 61537, IEC, VDE, and NEC standards for safety, load capacity, and fire protection . CE marking or UL classification ensures that the fitting meets regulatory requirements for electrical installations .Practical TipsEnsure the angle connector material matches the tray material to prevent galvanic corrosion.Verify that the bend radius does not exceed cable manufacturer recommendations to avoid damage.For complex routing, consider adjustable or modular fittings that can accommodate multiple angles, including 120°, without custom fabrication. By selecting the correct 120° angle connector and following proper installation guidelines, cable trays can maintain organized, safe, and code-compliant cable routing in any facility .
