Technical Description
Cable trunking is a fully enclosed cable management system designed to protect and organize cables in environments where safety and appearance are critical.
Unlike open cable trays, trunking systems completely surround the cables, providing enhanced protection against dust, moisture, and physical damage.
The removable cover design allows easy inspection and modification while maintaining a clean installation.
Applications
- Office buildings and commercial interiors
- Residential installations
- Hospitals and schools
- Retail and public spaces
- Data and communication systems
Customization
Custom sizes, materials, and finishes are available upon request to meet project-specific requirements.
Cable Trunking FAQ FAQs
Click a question to reveal the answer.
The cable trunking system is engineered and tested to meet IEC 61537, the definitive standard governing mechanical strength, corrosion resistance, and electrical continuity for cable tray and trunking systems. This compliance ensures that the product reliably supports insulated conductors under defined load classes and environmental conditions. Adherence to IEC 61537 provides specifiers with assurance of safe, code-compliant performance in building wiring, industrial equipment, and commercial installations where dependable cable management is critical.
Chinne Electric offers cable trunking manufactured from pre-galvanized steel, hot-dip galvanized steel, or stainless steel grades 304 and 316L. Finishing options include electrolytic zinc plating, hot-dip galvanizing to EN ISO 1461, and powder-coated polyester, each selected to meet specific environmental demands. These material and finish combinations deliver long-term corrosion protection, making the system suitable for everything from dry indoor installations to aggressive industrial or coastal atmospheres requiring enhanced durability.
The continuous perforation integrated into the trunking body enables organized cable routing, natural ventilation, and straightforward on-site modifications. Perforations are precision-engineered to preserve structural integrity under the load classes defined by IEC 61537, while allowing cable exits downward, to the right, or to the left without compromising the enclosure. This design simplifies branch circuit connections and accessory mounting, reducing installation time and ensuring a neat, serviceable cable management layout in complex commercial and industrial projects.
Yes, the system incorporates fire-resistant design principles and is constructed from non-combustible steel materials that limit flame spread. When installed in accordance with relevant wiring regulations and manufacturer guidelines, the trunking helps maintain circuit integrity for emergency power, fire alarm, and signaling systems. Its construction supports compliance with fire safety requirements often referenced alongside IEC 61537, providing a robust containment solution that safeguards critical circuits during a fire event in demanding building environments.
The cable trunking is offered in multiple load classes as classified by IEC 61537, determined by the dimensional profile, material gauge, and permissible support spacing. Light-duty classes handle small branch circuits with minimal cable weight, while medium and heavy-duty versions support main distribution routes with dense cable populations. Specifiers should select a load class based on total cable weight per meter and installation conditions to ensure deflection-free performance, sustained electrical continuity, and long-term protection of the enclosed conductors.
