The structure of individual wires and cables is quite different and moreover several cables can be put together in wire or cable bundles or ribbons. Power wires and cables: * Power transport and distribution networks Dry-insulated, armoured or unarmoured cables: o High and very high voltage, o Medium voltage. * Low-voltage cables, aerial or underground for distribution networks and connection. * Domestic wires and cables and appliance cords for mobile apparatus with a 750 V maximum rated voltage.
