[0002] Cables are usually rope-like cables made of several or several groups of wires twisted together. Each group of wires is insulated from each other and twisted around a center wire. The entire outside is covered with a highly insulating covering. Cables have the characteristics of internal power supply and external insulation. Cables include power cables, control cables, compensation cables, shielded cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc. They are all composed of single or multiple wires and insulation layers, and are used to connect circuits, electrical appliances, etc.

Existing cables offer poor termite and rat resistance and impact resistance, shortening their lifespan and impacting their safety. Therefore, it is necessary to develop an environmentally friendly, impact-resistant, rat-proof, and ant-proof power cable. Summary of the Invention

[0006] Furthermore, the cable core includes a conductor, a conductor shield, an insulation layer, an insulation shield and a copper tape shield which are arranged in sequence from the inside to the outside.

[0007] Furthermore, the conductor is made of copper, tinned copper, aluminum or aluminum alloy.

[0011] Furthermore, the buffer layer is a longitudinally wrapped buffer strip, and the buffer layer is made of polyurethane; and the high-temperature resistant composite layer is a ceramic silicone rubber composite belt.

[0012] Furthermore, the armor layer is a galvanized steel strip.

[0013] Furthermore, the outer sheath is made of low-smoke halogen-free polyolefin material, and the thickness of the outer sheath is 2.0 to 6.0 mm.

[0014] Furthermore, the rat and ant-proof coating layer is a flusilicide coating or a capsaicin coating.

[0015] The beneficial effects of the utility model are:

[0016] The cable of the present invention is provided with an armor layer, which can effectively protect the cable from being gnawed by rats and ants. The outside of the armor layer is provided with an anti-rat and ant coating layer.

The three cable cores 1 are wrapped with a low-smoke halogen-free glass fiber tape 2 on the outside, and a buffer layer 3 is provided on the outside of the conductor shield 12. The buffer layer 3 is a longitudinally wrapped buffer strip, and the buffer layer 3 is made of polyurethane. The buffer layer 3 made of polyurethane is added to the inside of the cable to effectively ensure that the cable core of the cable works normally and is not damaged when the cable is hit or vibrated. A high-temperature resistant composite layer 4 is wrapped around the outside of the buffer layer 3. The high-temperature resistant composite layer 4 is preferably a ceramic silicone rubber composite tape.

The steel strip armor 5 effectively protects against gnaws by rats and ants. The rat- and ant-resistant coating layer not only repels rats and ants but also protects the environment. The rat-proof and ant-proof coating layer can also be made of a mixture of capsaicin and o-isopropylphenylmethylcarbamate or 4-cyano 3-phenoxybenzyl-dextrorotatory cis-2,2-dimethyl-3-(2'2'-bromovinyl)cyclopropanecarboxylate, which can be evenly sprayed on the outer sheath to effectively prevent rats and ants from damaging the cable.
