A separator may extend in a longitudinal direction and include a body portion having an asymmetrical cross-sectional. Additionally, an outer periphery of the body portion may define a plurality of longitudinally extending channels including a first channel having a first cross-sectional area and a second channel having a second cross-sectional area different than the first cross-sectional area. At least one cavity may optionally extend through the body portion along the longitudinal direction. A first cable subcomponent including first transmission media may be positioned within the first channel, and a second cable subcomponent including second transmission media may be positioned within the second channel. A jacket may be formed around the separator and the subcomponents.

An electric cable for supplying power to aircrafts, rail vehicles, motor vehicles, ships or other devices is a single or multi-conductor cable and includes one or more current conductors with at least one insulation. A single or multi-layer outer casing is distributed over the periphery and is associated with the outwardly protruding reinforcing elements. The reinforcing elements are in the form of cooling ribs protruding preferably over the entire periphery of the cable and enable the surface of the cable to be increased and as a result, improve heat dissipation. The projecting reinforcing elements considerably reduce the risk of burning when the current conductors heat up and also protect the cable against abrasion. The invention also relates to a plug for the electric cable.
