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 sheath 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 method 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, the method comprising the steps of:
- guiding said conductors and said wire to a twisting point after said conductors and said wire pass through a storage path;
- twisting said conductors and said wire in alternating directions and/or rpm at said twisting point;
- guiding said tape for enveloping said wire separately from said wire in a lengthwise stretched condition along said storage path;
- and
- forming said tape into a sheath around said wire before or at said twisting point.
