Installation of Nordic power cable trays

Installing Nordic power cable trays requires careful planning, proper tray selection, secure mounting, and adherence to load and spacing guidelines to ensure safety and efficiency.

Planning the Installation

Before starting, review the approved shop drawings to determine the tray layout, lengths, and locations within electrical rooms, plant rooms, or service corridors. Inspect all materials upon delivery to ensure they match the approved submittal and are free from damage. Store trays horizontally on a flat surface with timber supports at one-meter intervals, protecting them from moisture and sunlight .

Selecting the Right Tray

Nordic Wire Tray offers ladder, perforated, and solid-bottom trays, each suited for different applications. Ladder trays allow airflow and easy cable entry, perforated trays support lighter loads, and solid-bottom trays protect sensitive cables. Choose the tray type based on cable type, load, and environmental conditions .

Mounting and Support

Use appropriate brackets, clamps, and fasteners for wall, ceiling, or floor mounting. Nordic trays are designed for easy installation with minimal fasteners, typically requiring only an M8 bolt and basic tools like a 13 mm wrench and bolt cutters . Support spacing generally ranges from 1.5 to 3 meters, depending on tray type and load, with a maximum load per hanger of 318–340 kg .

Installation Procedure

1. Align trays straight and level using connectors and fittings.
2. Cut and bend trays as needed using wire cutting machines or hand tools to adapt to site conditions .
3. Install center-hung supports where possible to allow cables to be deposited from both sides, speeding up installation .
4. Lay cables carefully, avoiding kinks and ensuring proper separation for power and data lines. Use cable tray rollers for long runs .
5. Secure all fittings and fasteners and verify alignment and load distribution.

Safety and Compliance

Ensure that qualified personnel perform the installation according to local electrical codes and safety standards. Proper installation prevents property damage, personal injury, and ensures the tray system performs as designed .

Customization and Flexibility

Nordic trays can be customized for unique project requirements, including different surface treatments, widths, and bends. This flexibility allows adaptation to complex layouts without compromising quality or installation speed . By following these steps, Nordic power cable trays can be installed efficiently, safely, and in compliance with industry standards, providing a durable and organized cable management solution.
