Abstract
An electrical power cable includes plastic-insulated conductors and a single wire, which is enveloped by a lengthwise incoming insulating tape and is twisted together with the conductors, all of which are surrounded by a common sheath. The conductors and the single wire are twisted together with alternating stroke directions (SZ), and the tape is loosely placed around the single wire in the form of a strand with opposing edges of the tape having alternating directions of rotation along the length of the strand.
Claims6
A device for manufacturing an electrical power cable of plastic insulated conductors and at least one wire enveloped by a lengthwise running insulating tape, said conductors and said tape enveloped wire being twisted together and surrounded by a common outer sheath, said device comprising:
- means for guiding said conductors, said wire and said tape through a storage path to a twisting point;
- means located at said twisting point for twisting said conductors, said wire and said tape at said twisting point as said conductors, said wire and said tape are guided by said guiding means;
- and
- intermediate storage means located in said storage path, said intermediate storage means including spaced guide disks having throughgoing apertures for said conductors and said wire to be twisted, said guide disks further containing an additional guide slot corresponding to said tape.
