Problems solved by technology

However, these two methods have their own shortcomings. For example, anti-rodent and anti-termite cables that add chemical substances such as capsaicin will emit a pungent smell when used, which will affect the normal work of maintenance personnel and the effect of anti-rodent and anti-ant. Relatively general; like the rodent-proof and termite-proof cables with hard casings, the structure is relatively bulky, and the flexibility of use is poor. This type of cable cannot be used in mechanical equipment and instrumentation systems.

Abstract

The invention relates to a cable protective sheath and a cable. The cable protective sheath comprises a protective sheath body and a power source. One side, in contact with the cable, of the protective sheath body is used as an inner side and one side, away from the cable, of the protective sheath body, is used as an outer side. The protective sheath body includes a shielding layer, a conductive layer and an insulating layer that are laminated successively from the inside to outside; the conductive layer is electrically connected to the power source; and the output voltage of the power sourceis lower than the body safety voltage. In addition, the cable includes the cable protective sheath. Compared with the anti-rat anti-ant cable in the prior art, the provided cable protective sheath andcable have advantages of good anti-rat and anti-ant effects, high usage flexibility, and simple structure.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a cable protective sheath and a cable. Background technique [0002] Cables are widely used in power systems, information transmission systems, mechanical equipment, and instrumentation systems due to their excellent transmission stability. Common cables in the prior art are mainly composed of conductive cores, insulating layers and sealing sheaths. , but the biggest damage to the cable in actual use is the bite of moths and rats, such as termites and mice, which are the most harmful to cables. [0003] There are two main types of anti-rodent and ant-proof cables in the prior art. One is to add some chemical substances that are disgusting to animals, such as capsaicin, in the sealing sheath of the cable to achieve the effect of preventing insects and rodents; the other is A layer of hard casing, such as a steel pipe, is placed outside the sealing sheath of the cable to prevent in...
