Anti-interference sheet one, anti-interference sheet two and anti-interference layer are provided to enhance the anti-interference ability of the cable, effectively reduce the interference of the outside world on the cable, and improve the transmission effect of the cable.

When subjected to external force, the position change of each wire core 5 inside the cable is reduced, thereby avoiding damage caused by friction between each other, and improving the service life of the cable. At the same time, the cooperation of the anti-interference piece 1 3 and the anti-interference piece 2 8 constitutes the first anti-interference defense line, and the anti-interference layer 9 forms the second anti-interference defense line, which enhances the anti-interference ability of the cable, effectively reduces the interference of the outside world on the cable, and improves the transmission effect of the cable.

[0025] During operation, when the cable is subjected to external force, the support skeleton 1 and the insulating layer 2 6 distribute and insulate the four insulating layers 4 containing the wire cores 5, the stress hole 12 and each stress hole 2 13 relieve the force of squeezing the deformation of the support skeleton 1, reduce the change in the position of the wire cores 5 inside the cable, and avoid damage caused by friction between each other, the reinforcing rib 14 increases the strength of the cable, avoids the cable from being broken and damaged by external force, and increases the service life of the cable, the anti-interference piece 1 3 and the anti-interference piece 2 8 cooperate to form the first anti-interference defense line, the anti-interference layer 9 forms the second anti-interference defense line, enhances the anti-interference ability of the cable, effectively reduces the interference of the outside world on the cable, and improves the transmission effect of the cable, the flame retardant layer 10 improves the fire resistance of the cable, and the anti-oxidation film 15 improves the anti-oxidation effect of the cable, and extends the service life of the cable.
[0026] Through the above steps, the support skeleton 1 and the insulating layer 2 6 inside the cable distribute and isolate the four insulating layers 1 4 containing the wire cores 5, so that each of them is in a relatively stable environment, thereby enhancing the stability of the structure and having good pressure resistance and buffering capabilities.
