“Conduit and cable trunking are both used in electrical and data communication systems to protect and organize wiring and cables, but they serve slightly different purposes and have different designs.
Conduit:
Conduit is a protective pipe or tube that is used to house and protect electrical wires and cables. It is typically made of materials like metal (e.g., steel, aluminium) or plastic (e.g., PVC). Conduits are used to contain and shield wires from physical damage, moisture, dust, and other environmental factors. They are commonly used in both residential and industrial settings.
Conduits come in various types:
Rigid Conduit: Made of rigid metal or plastic, providing high protection. Used in areas where cables are exposed to significant physical stress or environmental hazards.
Flexible Conduit: Made of flexible metal or plastic, allowing for easier installation in areas with bends or tight spaces.
Liquid tight Conduit: Designed to protect against water and other liquids, often used in outdoor or damp environments.
Cable Trunking:
Cable trunking, also known as cable ducting or cable raceway, is a system used to organize and enclose a group of cables within a single, larger structure. It is typically made of plastic or metal and comes in various shapes and sizes. Cable trunking is often used in commercial and industrial buildings to manage large bundles of cables and wires, reducing clutter and improving safety.
Cable trunking types and designs include:
Solid Cable Trunking: Fully enclosed, providing complete protection and organization for cables.
Slotted Cable Trunking: Has slots or openings along its length to allow for easy insertion and removal of cables without the need to disconnect them.
Channel Cable Trunking: Similar to solid trunking but consists of an open channel on one side, making it easier to add or remove cables.
Function, Size, and Design:
The primary functions of conduit and cable trunking are to protect, organize, and route electrical cables and wires. They help prevent damage to the wiring due to physical impact, moisture, dust, and other environmental factors. They also reduce the risk of electrical hazards and make maintenance and troubleshooting easier.
The size and design of conduit and cable trunking vary depending on factors such as the number and size of cables, the environmental conditions, and installation requirements. They come in a range of sizes, from small diameters suitable for individual wires to larger sizes for cable bundles. The design can include features like fittings, junction boxes, and mounting brackets to facilitate installation and connectivity.
When selecting conduit or cable trunking, it’s important to consider the specific needs of your application, including the type of cables, the environment they will be installed in, and any regulations or codes that may apply. Properly chosen and installed conduit and cable trunking contribute to the overall safety and efficiency of electrical and communication systems.”
