French Span Cable Tray Specifications

French long-span cable trays, such as the WRL range from Niedax, are pre-galvanized steel trays designed for heavy-duty cable support with compliance to European standards. Material and ConstructionLong-span cable trays in France are typically made of pre-galvanized steel according to DIN EN 10346, ensuring corrosion resistance and structural durability. They are often perforated, which allows for ventilation, heat dissipation, and easier cable management.

The trays are designed to support heavy cable loads over extended spans without intermediate supports, making them suitable for industrial and commercial installations.

Dimensions and Load Capacity

The WR

L long-span trays come in various widths and depths to accommodate different cable volumes. Span lengths are optimized to reduce the number of supports while maintaining mechanical integrity. Load capacity depends on tray width, material thickness, and span length, and must be verified according to the manufacturer's technical documentation.

Standards and Compliance

French cable trays comply with European directives and are CE marked, indicating conformity with safety and quality standards. Third-party certifications, such as LCIE for NF standards, ensure compliance with national regulations. These trays are designed to meet mechanical, electrical, and fire safety requirements under normal operating conditions.

Installation Considerations

Support spacing: Long-span trays reduce the number of supports but require careful calculation of load and deflection limits. Thermal expansion: Steel trays expand and contract with temperature changes; allowances must be made for thermal movement. Cable management: Perforations allow for secure cable tie-downs and routing flexibility.

Environmental factors: Corrosion protection and material selection should consider humidity, chemical exposure, and temperature extremes. ApplicationsLong-span cable trays are ideal for industrial plants, data centers, and large commercial facilities, where large volumes of power, control, and communication cables need reliable support over long distances. They provide mechanical and electromagnetic protection for cables while facilitating maintenance and future expansion.
