Abstract

The invention discloses an anti-pulling telescopic cable structure and relates to the technical field of cables. The anti-pulling telescopic cable structure comprises an outer protection layer, wherein a tensile buffer layer wraps an inner wall of the outer protection layer; an inner protection layer wraps the inner wall of the tensile buffer layer; the inner wall of the inner protection layer isfixedly connected with a damp-proof layer; the inner wall of the damp-proof layer is connected with insulating layers in a sliding manner; gaps between the damp-proof layer and the insulating layers are filled with filling materials; conductors wrap the inner wall of each insulating layer; and each insulating layer is formed by twisting. The anti-pulling telescopic cable structure has a telescopicstructure and has high anti-tensile property while the resistance to mechanical damage is not reduced; when the cable is subjected to tensile force, the tensile force can be buffered through deformation; and furthermore, internal wires are formed by twisting, the actual lengths of the wires are much greater than the length of the outer protection layer and the internal wires can be straightened and extended when stretched, and are not easy to break, so that the service life of the cable is prolonged.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to an anti-pull retractable cable structure. Background technique [0002] The cable is usually made of several wires or groups of wires twisted into a rope-like shape. Each group of wires is insulated from each other and is often twisted around a center. The entire outside is covered with a highly insulating covering layer. In the air or installed underground or underwater, it is used for telecommunications or power transmission. Cables can be divided into power cables, communication cables and control cables according to their uses. [0003] At present, the structure of the cable is relatively simple, does not have the function of stretching, and the resistance of the cable is very poor. During the installation process, the wires inside the cable are easily torn off, which seriously affects the implementation of power engineering and the maintenance of power equipment. use, and th...
