The standard thickness for Sudanese Trough-Type Cable Trays is typically 1.5 mm.

Sudanese Trough-Type Cable Trays, similar to other industrial cable trough systems, are generally manufactured with a metal thickness of 1.5 mm, welded to the inside flange side rails to provide a rigid structure and support for electrical cables . These trays may feature either a solid corrugated bottom or a ventilated bottom plate, depending on the application and ventilation requirements.

Material and Standards

The trays are usually made from hot-dip galvanized steel or equivalent corrosion-resistant metals, and they are designed to comply with NEMA VE-1 standards or equivalent IEC standards . The thickness ensures sufficient structural strength to support cable loads while maintaining durability and resistance to deformation.

Additional Considerations

• Side Rails and Fittings: The side rails are integral to the tray's strength, and fittings such as elbows, tees, and reducers are manufactured with the same material thickness to maintain uniform load capacity .
• Corrosion Protection: Edges and exposed areas are often coated with zinc-rich paint or galvanization to prevent corrosion, extending the service life of the tray .
• Load and Span: While 1.5 mm is standard, thicker trays (e.g., 2.0 mm) may be used for heavier cable loads or longer unsupported spans . In summary, 1.5 mm is the typical thickness for Sudanese Trough-Type Cable Trays, providing a balance between structural integrity, ease of installation, and compliance with international standards. For specialized applications, consulting the manufacturer's datasheet or project specifications is recommended to confirm the exact thickness required.
