Arcuated alloy interlocking multi-energy cable

Abstract

The present invention relates to a metallic cable, which comprises a cable core and a metal cladding around the cable core, wherein, the metal cladding is in an arc interlock buckled armor structure. Metallic cables in such a structure have greatly improved flexural property and can be laid smoothly; in addition, one or more cable cores can be combined into a cable as required for power transmission, control system, signal transmission, or illumination circuit, etc., and metal cladding can be added around the cable in an arc interlock buckled form to serve as a protective sheath and an earthing system for the cable to increase safety margin and protect the cable cores well; in addition, the coverage density of the metal cladding can be up to 100 percent, and therefore the shielding effect is more outstanding. The metal cable in the present invention is simple and practical in structure, and can be widely used especially in the building industry.

Description

technical field [0001] The invention relates to the field of electric transmission facilities, in particular to the field of cables, specifically a metal cable. Background technique [0002] With the increase in the demand for cables in all walks of life and the improvement of environmental protection requirements for cable laying and use, ordinary single-type cables can no longer meet the current needs, because of their low construction efficiency, high cost, and safety in laying and use. And environmental protection, especially in the construction industry, the cost of cable laying is high, more time-consuming and laborious, it needs to dig walls, wear pipes, poor bending performance, it is difficult to replace after damage, and even destroy the original building structure. [0003] There are currently three types of armoring, namely double-layer steel tape flat-folded armoring, steel wire armoring and wire braiding. Steel tape armor is suitable for the cable under compre...

Problems solved by technology

Although these two forms have a certain protective effect, the disadvantage is that the bending performance of the cable is limited, that is, the ratio of the bending radius to the diameter of the cable is about 20 times, and the metal wire braid has better bending performance, but its resistance to external force and mechanical The protective effect is insufficient, and the weaving density cannot reach 100%, and the shielding effect is limited

This greatly limits the application occasions of the cable, which brings great inconvenience to people's work and life.
