1. A charging cable for example for electric vehicles, wherein the charging cable has a first single line and a second single line, wherein the first single line has:
a cooling hose in which a cooling medium can be conveyed; and
a plurality of first uninsulated electrical conductors arranged around the circumference of the cooling hose and having a heat-conducting connection therewith such that the first uninsulated electrical conductors can be cooled by the cooling medium, wherein the second single line has:
a cooling hose in which a cooling medium can be conveyed; and
only one second uninsulated electrical conductor
arranged in the interior of the cooling hose and having a heat-conducting connection therewith such that the second uninsulated electrical conductor can be cooled by the cooling medium,
wherein:
the cooling hose of the first single line is in the form of a feed for the cooling medium and the cooling hose of the second single line is in the form of a feed for the cooling medium, and an additional hose is arranged in the charging cable as a return; or
