Cable trunking is an enclosure that helps provide protection for cables and wires that are used for electrical or networking purposes. By using this, you are essentially securing all of the numerous cables in a safe place so that they will not become worn or damaged, and they will not cause any trips or falls. There are several different types of cable trunking, with the main types being metallic, PVC, busbar and single, double or triple component.

Metallic trunking is formed out of a mild steel sheet material that is later coated with a fresh coating of grey or silver enamel paint (if the product is to be used indoors). If the metallic product will be used outdoors, or in locations where it has a possibility of becoming damp (such as in a basement), then it will instead be hot-dipped into a galvanised coating, so that the cables will be free from moisture and other damage. This format allows more cables to be drawn into one single system with ease, and due to all of the accessibility and electrical changes that tend to occur in the engineering field, metal trunking is designed to be accessed with minimal effort, which makes repairs and new installations much easier to carry out.

PVC is typically used in domestic and office settings. There are many types of fittings available so that PVC can be added to any type of area or space with very little difficulty. These helpful accessories (that can make your PVC installation job much easier) can usually be applied and secured to the trunking by using a helpful PVC solvent adhesive solution.

Busbar is made up of two main types, overhead and rising. The overhead type of busbar is used for the distribution of wires and cables along industrial premises. This type of enclosure is often seen in large factories or warehouses. They run at a very high level and the tap-off boxes that are used help to enable the machinery below to be moved about with ease. The system is all connected in the form of a ring, with switches that allow the system to isolate particular parts if necessary, without every machine being powered off.

The last on the list of cabling options would be compartment trunking in single, double or triple formats. Single compartment trunking is often used when there is just one cable that needs to be installed, such as for telephone cabling and many other electronic or data purposes. Double compartment trunking is used when there are two types of source cables coming from one single device including electric, data and telephone wires - or if two devices are using the same cable. The triple compartment type is used when all three types, electrical, data and telephone wires, need to be compiled together.

Hopefully, this guide to the different kinds of trunking should give you some idea of the type that you need to use in your workplace or home. In short, compartment and PVC types are most often seen in homes and offices, whereas busbar and metal are more likely to be found in a factory or warehouse.

There are four main types of cable trunking used in industrial and domestic settings. This guide looks at the uses of these different types of trunking to help potential purchasers choose the correct type for their needs.
