Nordic cable tray construction and installation

Nordic cable trays are designed for fast, flexible, and high-quality installation, with minimal tools and customizable configurations to suit any project.

Product Overview

Nordic Wire Tray (NWT) offers a wide range of wire trays, data racks, and accessories suitable for industrial and commercial cable management . Their X-Tray system is premium, durable, and adaptable, allowing trays to be cut, bent, and shaped to fit unique installation conditions. The trays require only an M8 bolt, bolt cutters, and a 13 mm wrench for assembly, reducing installation time and complexity . Stainless steel and other surface treatments are available for demanding environments.

Installation Guidelines

1. Planning and Site Preparation

• Ensure clear access for trays and tools, considering doors, pathways, and future maintenance .
• Assess the environment: temperature, humidity, dust, vibrations, and potential chemical exposure can affect tray performance .
• Verify structural support: floors, walls, or ceilings must handle the weight of trays and cables, especially for heavy-duty installations . 2. Tray Assembly and Support
• Assemble the tray system fully before pulling conductors to prevent cable damage .
• Maintain support spacing according to manufacturer specifications: standard trays typically require supports every 6–10 feet, while heavy-duty or long-span trays can extend up to 20 feet .
• For vertical or angled runs, fasten cables to transverse members; in horizontal runs, cable weight may suffice, but ties can improve spacing and heat dissipation .
• Allow at least 12 inches of vertical clearance above trays for installation and maintenance access . 3. Cable Management and Safety
• Use only Tray Rated (Type TC) or Metal-Clad (Type MC) cables suitable for open-air environments .
• Maintain fill limits: power cables ≤40% of tray cross-section, control cables ≤50% .
• Separate high-power and low-power cables to prevent electromagnetic interference (EMI), .
• Metallic trays can serve as equipment grounding conductors if compliant with NEC requirements .
• For outdoor or long runs, install expansion splice plates to accommodate thermal expansion . 4. Customization and Adaptation
• Nordic trays can be cut, bent, and shaped using wire cutting machines to fit unique layouts .
• Fewer fasteners and parts reduce installation time, making the system cost-effective and efficient . 5. Maintenance Considerations
• Regularly inspect trays for mechanical integrity, corrosion, and cable spacing .
• Ensure cables remain secure and properly supported to prevent sagging or overheating .
• Follow local building codes and environmental regulations for safety and compliance .

Key Takeaways

Nordic cable trays provide a flexible, high-quality solution for cable management. Proper planning, adherence to support spacing, cable type selection, and compliance with NEC and local codes ensure safe, efficient, and long-lasting installations. Their modular design and minimal tool requirements make them ideal for projects of any size or complexity .
