Abstract
An electrical line has a core and an insulating sheath that is extruded onto the core. A structured surface having a plurality of structural elements stamped into it is formed over the entire surface of the insulating sheath. The stamped structure is a microstructure, wherein the individual structural elements have a stamping depth of at most 0.15 mm.
Claims15
An electrical line extending in a longitudinal direction, the electrical line comprising:
- a core;
- and
- an insulating sheath extruded onto said core, said insulating sheath having a structure extending in the longitudinal direction and said structure having plurality of structural elements being stamped into said insulating sheath to form a structured surface, said structured surface having a form of an imbricated surface and said structural elements each taking a form of an obliquely positioned imbricated form, wherein a plurality of obliquely positioned imbricated forms taking a form distributed in a peripheral direction.
A method for manufacturing an electrical line extending in a longitudinal direction, which comprises the steps of:
- providing a core;
- extruding an insulating sheath onto said core;
- and
- stamping a structured surface having a plurality of structural elements into the insulating sheath still being soft downstream of an extrusion of the insulating sheath, the structured surface having a form of an imbricated surface and the structural elements each taking a form of an obliquely positioned imbricated form, wherein a plurality of obliquely positioned imbricated forms taking a form distributed in a peripheral direction.
