Cable and method for the production thereof

1. A cable comprising:

an electrical conductor;

a silicone sheath surrounding the conductor; and

a separation layer arranged between the conductor and the silicone sheath, the separation layer being made of a silicone material that has a lower adhesion to the conductor than a material of the silicone sheath,

wherein at least one filler is added to the silicone material for the lower adhesion of the separation layer as compared with the silicone sheath, wherein either silicon dioxide or silicic acid is used as the filler with a proportion in the silicone material being in a range from 30 percent by weight to a maximum of 60 percent by weight, and wherein an identical heat curing silicone based on diorgano(poly)siloxanes is used for the silicone material and for the silicone sheath so that the silicone sheath and the separation layer differ only by the filler, and

wherein the separation layer directly contacts the conductor and the silicone sheath forms the outermost layer of the cable.

2. The cable according to claim 1 , wherein the separation layer is integrally joined to the silicone sheath.

3. The cable according to claim 1 , wherein the silicone material has a higher density than the silicone sheath.

4. The cable according to claim 1 , wherein the silicone material has a density in a range from approximately 1.5-1.8 g/cm 3 .

5. The cable according to claim 1 , wherein the conductor is made of aluminum or an aluminum alloy.

6. The cable according to claim 1 , wherein the conductor is a stranded conductor.

7. The cable according to claim 1 , wherein silicic acid is used as the filler, the silicic acid being pyrogenic silicic acid.
