Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a corrosion-resistant cable. Background Art

[0002] Cables are typically made up of several or several groups of conductors (at least two in each group) twisted together like ropes. Each group of conductors is insulated from each other and often twisted around a central core. The entire cable is covered with a highly insulating layer. Cables have the characteristics of being electrically conductive inside and insulated outside.

[0003] Traditional cables generally have a rubber insulation layer directly on the outer layer of the cable core to achieve insulation, and then are coated with waterproof paint and other materials on the outer layer to provide protection. However, the overall protection performance and corrosion resistance are still poor, especially when used in humid and dark environments. Due to the large number of snakes, insects, rats and ants, the cables are severely eaten, the surface of the cables are broken, and the corrosion resistance of the cables is further reduced.

[0025] Reference Figure 1-4A corrosion-resistant cable comprises a cable core 1, the outer layer of the cable core 1 is sequentially provided with an insulating sleeve 2, a shielding layer 6 and a protective layer 3, the protective layer 3 comprises a first protective sleeve 8, a second protective sleeve 9 and a second partition 7, the second protective sleeve 9 is provided on the outer layer of the first protective sleeve 8, and the second partition 7 is evenly provided on the surface of the first protective sleeve 8 and the second protective sleeve 9 to achieve a state in which the first protective sleeve 8, the second protective sleeve 9 and the second partition 7 form a whole, and the second partition 7 protrudes from the second protective sleeve 9. The protective layer 3 is made of PVC material. The PVC protective layer 3 formed by the first protective sleeve 8 and the second protective sleeve 9 provides double protection, which enhances the protective effect of the entire cable and enhances the overall corrosion resistance. The second partition 7 arranged at intervals makes the protective layer 3 made of two layers of PVC stronger and has a better protective effect.

[0026] Furthermore, a uniformly distributed cavity 10 is formed between the first protective cover 8, the second protective cover 9 and the second partition 7, and the interior of the cavity 10 is filled with insect-proof powder 5. The filled insect-proof powder 5 can be used to repel insects and ants when they damage the outer layer of the cable, thereby reducing the corrosion of the cable by insect feces or corpses.

[0027] Furthermore, the interior of the cavity 10 is evenly provided with a first partition 4 to achieve a state in which the internal space of the cavity 10 is evenly divided. By dividing the cavity 10, the insect-proof powder 5 inside can be reduced from falling to the lowest point due to the influence of gravity, resulting in the phenomenon that the surface above the cable is not protected by the insect-proof powder 5.

[0028] Furthermore, the shielding layer 6 includes a first shielding sleeve 12 and a second shielding sleeve 13. The second shielding sleeve 13 is arranged on the outside of the first shielding sleeve 12, and polyurethane foam is filled between the first shielding sleeve 12 and the second shielding sleeve 13 to achieve the state of improving the heat dissipation effect of the cable and reducing the damage to the cable caused by external mechanical shock or pressure. The shielding layer 6 is made of semiconductor paper wrapped with copper tape.

[0029] Furthermore, a steel wire 11 is wound around the surface of the first shielding sleeve 12, and the steel wire 11 is made of spring steel. By setting the steel wire 11, the toughness of the entire cable can be enhanced, and the phenomenon that the cable is easily bent due to stress and causes damage to the outer layer can be reduced. The set steel wire 11 can enable the entire cable to have the function of automatic straightening.

[0030] Furthermore, the insulating sleeve 2 is made of butyl rubber, which is an elastic insulating material with excellent electrical properties and chemical resistance. It can maintain good flexibility and elasticity in a wide temperature range, and is therefore often used in power cables and control cables in high temperature and vibration environments.

[0031] In summary, the PVC protective layer 3 formed by the first protective sleeve 8 and the second protective sleeve 9 provides double protection, which strengthens the overall protective effect of the cable and enhances the overall corrosion resistance. The second partition 7 set at intervals makes the protective layer 3 made of the two layers of PVC stronger and has a better protective effect. The filled insect-proof powder 5 can be used to drive away insects and ants when they damage the outer layer of the cable, thereby reducing the corrosion of the cable by insect feces or corpses. By dividing the cavity 10, the insect-proof powder 5 can be reduced in the interior due to the influence of gravity and fall to the lowest point, resulting in the surface layer above the cable not being protected by the insect-proof powder 5. The filled polyurethane foam can improve the heat dissipation effect of the cable and reduce the damage to the cable caused by external mechanical shock or pressure. By setting the steel wire 11, the toughness of the entire cable can be enhanced, and the phenomenon of the cable being easily bent due to stress and causing damage to the outer layer can be reduced. The set steel wire 11 can enable the entire cable to have the function of automatic straightening.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
