How Do Power Cables Work?

Feb. 18, 2019

Power Cables Operate by providing a low resistance path for the current to flow through. Electrical cables consist of a core of metal wire offering good conductivity such as copper or aluminium, along with other material layers including insulation, tapes, screens, armouring for mechanical protection, and sheathing. These additional layers are designed principally to allow the metal core to continue to conduct electrical current safely in the environment it is installed in.  

The simplest electrical cable may just be a metal conductor - these Insulated Power Cables are used as overhead line wires manufactured without any insulating material around the conductor other than the air that surrounds the conductor. Insulated Overhead Cable such as those used in the rail industry, require practical considerations to ensure that the cable is isolated from any means of accidentally grounding the electrical conductor (grounding the cable would see the current pass through it, electrocuting anyone in contact).
