Description

Technical Field

[0001] The invention relates to the technical field of cables, and in particular to an anti-aging photovoltaic cable that is resistant to ant and rat gnawing. Background Art

[0002] Photovoltaic cable refers to the cable used for power transmission in the DC side circuit of the solar photovoltaic power station system. It has excellent physical properties such as resistance to high and low temperatures, resistance to ultraviolet radiation, waterproofness, resistance to salt spray, resistance to weak acids and alkalis, resistance to aging, and flame retardancy.

[0003] However, for cables laid underground, especially in hot and humid areas such as Southeast Asia and southern my country, termites frequently erode the plastic sheath of cables. Termites not only gnaw on the cables, but also secrete formic acid, which seriously corrodes the insulation and sheath of the cables, causing the insulation performance to deteriorate or even short circuit. The damage to underground cables by mice is mainly mechanical damage caused by gnawing. For this reason, most underground cables have proposed rodent repellents and ant repellents, and the appearance and operating status of the cables are regularly checked. However, rodent repellents and ant repellents have a shelf life. After a period of use, they lose their effectiveness, and thus their protective effect.

When buried underground, the integrated sound wave generating mechanism can emit sound waves regularly, which can drive away ants and rats on the one hand, and on the other hand, the surface of the cable can be observed after the sound wave sensor 171 receives the reflected sound wave signal to ensure that any damage caused by anything other than ants and rats is discovered in time. By sending sound waves and receiving their reflected waves, it can be determined whether there are any larger rodents approaching the cable. When discovered, the electronic pulse generating mechanism sends electronic pulses to drive away the larger rodents and protect the cable. The arrangement of the external heat shrinkable layer 11, the outer protective layer 7, the inner protective layer 8 and the internal shielding layer 9 can greatly enhance the anti-aging effect of the cable body 1.
