Abstract
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.
Claims21
A multi-conductor cable, comprising:
- a plurality of electric cables for supplying power, each of the plurality of electric cables comprising:
- a central conductor;
- at least one insulation layer around the central conductor;
- a return conductor comprising a plurality of individual conductors twisted together, the return conductor being arranged concentrically around the at least one insulation layer;
- and
- an outer casing around the return conductor, the outer casing including reinforcing elements projecting outwardly in a direction away from the return conductor and being situated over only a part of an outer circumference of the outer casing such that another part of the outer circumference of the outer casing does not have any reinforcing elements, the reinforcing elements extend along a length of the electric cable in a helical shape or a meandering shape,
- the another parts of the outer circumferences of the electric cables being in reciprocally contacting areas of the electric cables such that the outer casings of the electric cables are reciprocally in contact with one another.
