Description

Technical Field

[0001] The utility model belongs to the technical field of wire and cable, and relates to flexible cables, in particular to a light-duty flexible environmental protection anti-rat and anti-ant cable. Background Technique

[0002] Rats and ants are one of the main hazards that damage cables. When these damaged cables are exposed to moisture or immersed in water, they are prone to leakage and short circuit, which can cause power outages, telecommunications interruptions, fires, and even explosions. Especially in some forest areas and mountainous areas, where there is abundant rain, suitable for rats and ants to multiply and thrive, and the population is sparse, it poses a great threat to the safe and stable operation of cables. Therefore, when designing and producing cables, the possibility of preventing rats and ants from gnawing should be fully considered.

[0003] There are chemical methods and physical methods for preventing rats and ants from damaging the cable body.

[0004] The chemical method for preventing rats and ants is to add repellents, such as capsaicin, to the sheath material of the cable to drive away rats and ants, or add toxic substances to poison rats and ants to death. However, it will cause environmental pollution and health harm to producers and construction installers; when the rat and ant-proof sheath is buried underground for a long time, its drug effect will gradually decrease. Especially in an environment with relatively high humidity, it is easier for the drug effect of the rat and ant-proof material to dissipate or even disappear, and ultimately rats and ants will still gnaw on the sheath. Therefore, the chemical method for preventing rats and ants cannot well protect the cable from being bitten by rats and ants.

[0005] The physical method for preventing rats and ants is to use the hardness of the cable sheath material to prevent rats and ants from damaging it, or to use a cable sheath with a relatively high smoothness to prevent rats and ants from gnawing. The physical method for preventing rats and ants increases the structure of the cable, resulting in an increase in the production cost of the cable and sacrificing the bending performance of the cable, which is not conducive to construction and laying.
