COOLABLE SINGLE LINE AND CHARGING CABLE

A single line for a charging cable includes an open support structure () having a longitudinal extent, at least one channel conductor () made of electrically conductive material, and an insulation (). The at least one channel conductor () wraps around and contacts the open support structure () along its longitudinal extension. The insulation () wraps the open support structure () and the at least one channel conductor (). At least one channel () for a cooling fluid () is provided and is formed by the support structure () and the channel conductor (). The insulation () is impermeable to the cooling fluid () and is electrically insulating.
