Abstract
A multi-striped electrical cable may be provided. The multi-striped electrical cable may comprise a conductor, an inner layer, an outer layer, and a stripe. The conductor core may comprise a conductor. The inner layer may be around the conductor core and may comprise an inner layer polymer. The outer layer may be around the inner layer. The outer layer may comprise an outer layer polymer, an outer layer colorant, and an outer layer friction reducing additive. The stripe may be disposed on an outermost portion of the outer layer. The stripe may comprise a stripe polymer, a stripe colorant, and a stripe friction reducing additive.
Claims21
An electrical cable comprising:
- a conductor core comprising a conductor;
- an inner layer around the conductor core, the inner layer comprising an inner layer polymer;
- an outer layer around the inner layer, the outer layer comprising an outer layer polymer, an outer layer colorant, and an outer layer friction reducing additive, wherein the outer layer friction reducing additive comprises a first friction reducing additive;
- and
- a stripe disposed in an outermost portion of the outer layer disrupting concentricity of the outer layer, the stripe comprising a stripe polymer, a stripe colorant, and a stripe friction reducing additive, wherein the stripe friction reducing additive comprises a second friction reducing additive, wherein at least a portion of the stripe friction reducing additive is present throughout the stripe, the outer layer and the stripe forming a continuous outer contour for the electrical cable, wherein the outer layer friction reducing additive is present throughout a thickness of the outer layer wherein the inner layer, the outer layer, and the stripe comprise a multi-layer flow attached to the conductor core, and wherein a distance between an outside surface of the stripe and a center of the conductor core is equal to a distance between an outside surface of the outer layer and the center of the conductor core, and
- wherein the outer layer polymer is a polyamide;
- and
- wherein the stripe polymer is different than the outer layer polymer.
