Power cable: It is used for supplying current to load. It is of larger current carrying capacity available in single core, 2 cores, 3 cores, 3 cores, and 4 cores. Single core is available upto 1000 mm2 . Usually power cables are of aluminium. These cables are graded for higher voltages and possess more cross section area.
Control cable: Control cables are used for control purposes for logics, indication or annunciation etc. These are of lower current carrying capacity and voltage grading is also less. These are of less cross sectional area are available in pairs of 2,5,10,25,50 etc.
