Mains AC cables are used to connect devices to the power grid. They provide good quality insulation that guarantees safety of use and protection against electric shock while being highly flexible. They are manufactured in versions with a two-pin C8 plug, flat plug, and plug with a three-pin C13 or C5 with black or white plastic. Lengths from 1 to 5 meters are available. The diameters of copper conductors range from 0.5 mm2 through 0.75 mm2 to 1.5 mm2 for cables with the highest load capacity. In addition to the European versions, there are also versions for foreign markets (British, American), without a plug, extension cords and similar types.
