“Metal trunking, also known as cable trunking or wireway, is a type of conduit used in electrical installations to protect and route electrical cables and wires. It is commonly used in large projects such as commercial buildings, industrial facilities, data centers, and infrastructure projects. Trunking provides a safe and organized pathway for cables, helping to prevent damage, ensure compliance with electrical regulations, and simplify cable management.
Here’s how metal trunking is used and installed on large projects:
Cable Protection: The primary purpose of metal trunking is to protect electrical cables and wires from physical damage, environmental factors, and interference. It prevents accidental contact with live wires and reduces the risk of fire hazards.
Cable Management: In large projects, there are usually a substantial number of cables and wires that need to be installed. Trunking allows for neat and organized cable management, making it easier to identify and access specific cables when maintenance or repairs are required.
Compliance with Regulations: Electrical codes and regulations often require proper cable protection and management to ensure the safety of occupants and the integrity of the electrical system. Metal trunking helps meet these regulatory requirements.
Ease of Installation: Metal trunking is designed to be easy to install, especially when compared to the complexities of directly laying and securing individual cables. It allows for a quicker and more efficient installation process, saving time and labour costs.
Flexibility and Adaptability: Metal trunking comes in various sizes and configurations, providing flexibility to accommodate different cable types and installation scenarios. It can be easily modified or expanded to suit changing project requirements.
Durability: Metal trunking is made from robust materials like steel or aluminium, making it highly durable and capable of withstanding harsh environments or potential impacts.
The installation process for metal trunking typically involves the following steps:
Planning and Design: Before installation, the electrical layout and cable routes should be carefully planned to determine the required length and configuration of trunking.
Mounting: Trunking is usually fixed to walls, ceilings, or floors using brackets, screws, or other appropriate mounting hardware. Proper positioning and spacing are essential to ensure efficient cable routing.
Cutting and Bending: Trunking may need to be cut or bent to fit specific sections or corners of the building. Special tools are used to achieve precise cuts and bends.
Cable Routing: Once the trunking is installed, cables and wires are routed through it according to the predetermined plan.
Cover Installation: After the cables are placed inside the trunking, covers or lids are fixed to secure and protect the cables, while still allowing access for maintenance purposes.
Testing: After installation, electrical testing is carried out to ensure proper functionality and compliance with safety standards.
It’s important to note that electrical installation should always be performed by qualified and experienced professionals to ensure safety and compliance with local regulations.”
