|‘An assembly made up of cable or busbars and parts, which secure, and if necessary, enclose the cable or busbars.’|
A cable, in the context of electrical installations in buildings, is an insulated conductor of electricity, usually copper or aluminium, with a protective casing which acts as an insulator. Cables are used to transmit electrical energy or data or telecommunications signals from one point to another.
- They are flexible enough to be drawn through or laid into a containment system.
- Where appropriate, they can be clipped directly or suspended from a building’s structure.
Cable insulation materials may comprise common plastics such as polyvinyl chloride (PVC), modified synthetic materials, or rubber. Other forms of insulation include mineral powder housed within a metallic outer casing.
The way different cables behave when subjected to fire conditions is the subject of extensive research. Toxic gas emissions, density of smoke and fire propagation speeds can vary widely with different forms of cable. This is a key consideration when selecting materials for buildings.
