Power as well as control cables are key components of any electrical system and have distinct purposes. In systems of automation and control, control cables serve for signal transmission as well as control of the devices. They usually consist of several conductors with an electromagnetic interference shielded insulation. On the other hand, power cables are used to convey electric power and are created to bear higher voltage and current. Knowing the difference between these two types of cables is very important in selecting the correct type of cable that will match the specific application and promote safety and value for money towards electrical systems.
