Copper core foaming insulation polyurethane sheath flexible cable

Abstract

The invention discloses a copper core foaming insulation polyurethane sheath flexible cable, and relates to the technical field of sheath flexible cables, the copper core foaming insulation polyurethane sheath flexible cable comprises a cable core, a foaming layer and a positioning mechanism, copper core wires are arranged in the cable core, a first filling layer is arranged between the copper core wires, an inner wrapping layer is arranged on the outer side of the cable core, the flexible rubber strips are arranged in the inner wrapping layer, the second filling layer is arranged between the flexible rubber strips, the compression-resistant layer is arranged on the outer side of the inner wrapping layer, the supporting strips are fixed in the compression-resistant layer, the carbon fiber belt is arranged on the outer side of the compression-resistant layer, and the foaming layer is arranged on the outer side of the carbon fiber belt. The cable has the advantages that the cable is provided with the inner wrapping layer, the outer side of the cable core is wrapped by the inner wrapping layer, the flexible rubber strips are annularly and evenly distributed in the inner wrapping layer, the structural strength of the inner wrapping layer can be enhanced due to the arrangement of the flexible rubber strips, and the flexible rubber strips which are annularly and evenly distributed can play a role in pressure resistance.

Description

technical field [0001] The invention relates to the technical field of flexible cables, in particular to a flexible cable with a copper core foam insulation polyurethane sheath. Background technique [0002] Flexible cables are the preferred cables for power transmission materials and signal transmission carriers in towline motion systems, also known as: towline cables, tow cables, mobile cables, robot cables, etc. The conductor structure of the flexible cable is mainly based on the stranded copper conductor structure of DIN VDE 0295 and IEC 228 standards. The sheath is mostly made of low-viscosity, flexible and wear-resistant materials to slow down the wear rate of the cable during continuous back-and-forth movement. [0003] The existing flexible cables have insufficient compressive performance and structural strength, and the protection effect is not good, the outside is easy to wear, and it is not convenient to install stably with the wire slot, and the cable may be move...
