A cable, especially a data transfer cable, has at least one wire having an inner conductor and a wire sheath which has been applied directly thereto. The wire sheath has a dielectric layer composed of a foamed uncrosslinked thermoplastic polymer, preferably polyethylene or polypropylene, and the dielectric layer is encased by an outer skin layer composed of unfoamed, chemically crosslinked polyethylene. The specific wire sheath leads to a distinct improvement in soldering properties. Additionally specified are a corresponding wire and a production process therefor.
