The utility model, by winding the filling rope around the outer surfaces of multiple cores inside the cable, can restrain the multiple cores from each other. When connecting, the annular ring needs to be fitted on the outer surfaces of the multiple cores first, and then the filling rope is wound around the outer surface of the annular ring, so that the multiple cores can be restrained from each other, and the cores are isolated by the skeleton, thereby preventing the problem of multiple cores inside the cable being misaligned from each other during use. The polypropylene filling rope in the filling layer can effectively protect the cable body, and the flame retardant layer is a mica material that is a heat-insulating flame retardant material, which effectively prevents the transfer of heat and avoids causing fire.

Description

Technical Field

[0001] The utility model relates to the technical field of cable filling ropes, in particular to a filling rope for isolating multi-core cables. Background Art

[0002] A cable is made of one or more mutually insulated conductors and an outer insulating protective layer. It is a wire that transmits electricity or information from one place to another. It is usually a rope-like cable formed by twisting several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center.

[0003] Currently, when filling ropes are used to fill multi-strand cables, the existing filling ropes are directly in contact with the cable sheath after being wound around the outer surface of the wire core. When pulling occurs, the contact portion between the filling rope and the cable sheath is easily damaged, resulting in a decrease in the friction between the mutual friction, causing the wire core to slide inside the cable sheath, and in severe cases, causing two adjacent wire cores to be entangled with each other.
