Swiss cable tray thickness

Cable tray thickness in Switzerland typically ranges from 1. 0 mm to 3. 0 mm depending on tray type, load requirements, and material, following European standards.

Standard Thickness Ranges

Cable tray thickness is a critical factor affecting load capacity, span, and durability. In practice: Ladder trays: Designed for heavy cable loads and long spans, side rail thickness usually ranges from 1. 5 mm to 3.

0 mm for steel trays, with thicker rails for larger widths or higher loads. Perforated or trough trays: Provide continuous support with ventilation; typical thickness ranges from 1. 0 mm to 2.

5 mm depending on material and load. Wire mesh trays: Lightweight and flexible, generally 1. 0 mm to 2.

0 mm thick, suitable for smaller cable bundles or data cabling.

Material Considerations

Galvanized steel: Thickness may vary slightly due to galvanization; hot-dip or electro-galvanized coatings add a small layer but do not significantly change structural thickness. Aluminum trays: Often slightly thicker than steel for equivalent load capacity due to lower material strength. Stainless steel: Used in corrosive environments; thickness is selected based on mechanical load rather than corrosion resistance alone.

Compliance and Standards

Swiss installations generally follow European directives and IEC standards, which define minimum mechanical and electrical requirements for cable trays.

C

E marking indicates compliance with these standards. While Swiss-specific regulations exist, they align closely with EN 61537 for cable management systems, which specifies material thickness ranges for different tray types.

Practical Selection Tips

Choose thicker trays for heavy power cables or long unsupported spans. For lightweight or data cabling, thinner trays are sufficient. Always verify load ratings and span tables provided by manufacturers like Legrand or ABB to ensure compliance and safety.

Consider environmental factors such as humidity, temperature, and potential chemical exposure when selecting material and thickness. In summary, Swiss cable tray thickness typically ranges from 1. 0 mm to 3.
