Problems solved by technology
[0002] In the occasion where the equipment unit needs to move back and forth, in order to prevent the cables from being entangled, worn, pulled off and scattered, the cables are often put into the cable drag chain to protect the cables, and the cables can also move back and forth with the drag chain. The highly flexible special cable that moves back and forth with the drag chain and is not easy to wear is called drag chain cable. It is mainly used in industrial electronic systems, automatic production lines, storage equipment, robots, fire protection systems, cranes, CNC machine tools and metallurgical industries. Due to the particularity of the use of towline cables, the requirements for towline cables are relatively high, such as the requirements for low temperature resistance. The low temperature performance requirements of chain cables have been further improved. The existing drag chain cables can no longer meet the needs of current industrial development. There is an urgent need for a cable with good low temperature resistance.

Embodiment Construction
[0012] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.
[0013] Such as Figure 1 to Figure 2 As shown, a low temperature drag chain cable includes a sheath 1, an insulating layer 5 and a conductor 6, the insulating layer 5 is wrapped on the outer surface of the conductor 6, and the axis of the sheath 1 is provided with a tensile guide Core 7, the central part of the tensile guide core 7 is provided with a circular through hole 701, on the one hand, the circular through hole 701 can improve the flexibility of the cable after molding, compared with the traditional solid tensile guide core, the flexibility Better, so that in the actual use process, the cable itself can better adapt to the movement of the equipment unit; the insulating layer 5 is evenly and symmetrically distributed on the outside of the tensile guide core 7, and the outer surfa...

The invention relates to a low-temperature-resistant trailing cable which comprises a sheath, insulating layers and a conductor, wherein the insulating layers are arranged on the outer surface of the conductor in a wrapping mode, a tensile conductive core is arranged at the position of the axial center of the sheath, a round through hole is formed in the middle of the tensile conductive core, the insulating layers are evenly and symmetrically distributed on the outer side of the tensile conductive core, the outer surfaces of the insulating layers are wrapped in a first heat insulation layer, a second heat insulation layer is arranged on the inner wall of the sheath, and the first heat insulation layer is wrapped in the second heat insulation layer. The low-temperature-resistant trailing cable has the advantages of being reasonable in structural design, long in service life, good in low-temperature resistance and the like. The first heat insulation layer and the second heat insulation layer are adopted for heat insulation of the conductor, the low-temperature resistance of the cable is improved, and then normal work of instruments and equipment can be ensured at low temperatures so that requirements of industrial development can be better met.
