Cable tray crossarm models and specifications

Cable tray crossarm models and specifications

Cable tray support crossarms are typically made of galvanized steel, with U- or L-shaped cross-sections, thicknesses of 2.5–4 mm, lengths matching tray width, and designed to meet static and dynamic load requirements.Material and ConstructionCable tray crossarms are generally fabricated from Q235 low-carbon steel and finished with hot-dip galvanization to resist corrosion, including passivation via chromate treatment to seal zinc pores . Cross-sectional shapes are usually U-shaped or L-shaped, providing structural rigidity while supporting cable trays .DimensionsThickness: 2.5 mm, 3 mm, or 4 mm depending on load requirements .Length: Matches the width of the cable tray, commonly 300 mm, 400 mm, or 500 mm .Flange width: For heavy-load applications, flange widths are increased to 60–80 mm .Load CapacityCrossarms must support both static and dynamic loads:Light-duty trays (control cables): 50 N/mPower cable trays: 150–200 N/mHeavy-duty industrial trays (e.g., metallurgical workshops): >300 N/m, requiring stiffened structures . Deflection limits are specified as ≤ L/200, meaning a 1000 mm span should not sag more than 5 mm .Support SpacingCrossarms are bolted to cable tray connectors, forming support nodes with spacing between 500–1000 mm . For optimal system performance, 1/4 span support placement is recommended to minimize stress and deflection at splice locations .Standards and ComplianceGB 50217: Code for Design of Cables in Electric Power Engineering, specifying deflection and load requirements .DIN EN 61537: Defines cable support systems, including materials, installation, and environmental considerations .NEMA BI 50015/50016: Guidelines for cable tray support locations and installation practices .Installation NotesCrossarms are fixed to cable tray connectors using bolts, ensuring secure attachment. For heavy-duty applications, stiffened crossarms with wider flanges are recommended. Proper galvanization and inspection ensure long-term durability in industrial environments . By following these specifications, cable tray support crossarms can safely support electrical and communication cables while complying with international standards.
