The high-security cable has good corrosion resistance, fire resistance and waterproof performance, and can withstand the attack of insects, ants and mice. However, in the use of high-security cables, there will be bends in the cable when it is arranged, and the outer side of the bend of the cable will be in a tight state, and the thickness of the outer layer at this place will become thinner. When subjected to friction, the wear resistance is poor and it is easy to be damaged, causing the core to leak, resulting in the safety performance of the high-security cable not being optimal and the service life being shortened.
