There are multiple core units 1. The shaping component 2 is disposed outside the multiple core units 1. The cold-resistant rod 3 is disposed inside the shaping component 2 and corresponds to the shaping component 2. The armor layer 5 is wrapped around the outside of the shaping component 2. The change-resistant rod 4 is disposed between the shaping component 2 and the armor layer 5. The outer sheath 9 is disposed outside the armor layer 5.

[0020] In this embodiment, the cold-resistant rod 3 is made of polyether TPU material, which has characteristics such as high strength, hydrolysis resistance, high resilience, and low-temperature performance. This allows the cable to have high mechanical strength, withstand greater external forces without damage, and has good pressure resistance, thus protecting the cable core unit 1. Furthermore, the polyether TPU material does not become overly brittle or lose elasticity at low temperatures like other materials. The anti-deformation rod 4 is made of stainless steel fiber material, which has good tensile and deformation resistance, thereby enhancing the cable's toughness and reducing cable bending and breakage. The armor layer 5 is made of flat steel wire stranded together. When the cable is subjected to external pressure, the pressure passes through the armor layer 5, which provides pressure resistance to the cable. In other embodiments not shown, the armor layer 5 may also be made of round steel wire, round copper wire, or flat copper wire stranded together. The outer protective layer 9 is made of neoprene rubber, which has high strength, good durability, excellent wear resistance, flame retardancy, light resistance, ozone resistance and atmospheric aging resistance, and good elasticity, and is resistant to impact and vibration.

[0021] The cable core unit 1 includes a cable core 11 and an insulation layer 12, which wraps around the outside of the cable core 11. In this embodiment, the cable core 11 is made of aluminum alloy, and the insulation layer 12 is made of highly insulating irradiated cross-linked polyethylene insulation material, thereby isolating the cable core 11 and preventing electric shock injury to the user. In this embodiment, there are six cable core units 1.

[0022] The shaping assembly 2 includes a core rod 21, a separator plate 22, an arc-shaped plate 23, and a separator 24. The core rod 21 is positioned at the middle of multiple cable core units 1. The separator plate 22 is positioned between two adjacent cable core units 1 and is used to separate the two adjacent cable core units 1, thereby preventing them from tangling and providing anti-torsion performance. The arc-shaped plate 23 is positioned between two adjacent separator plates 22. The separator 24 is fixedly connected to the separator plate 22. The separator 24 has a hexagonal star-shaped cross-section. In this embodiment, the shaping assembly 2 is made of 125°C irradiated cross-linked halogen-free, low-smoke, flame-retardant polyolefin insulation material.

In this embodiment, the waterproof layer 6 is a waterproof and breathable membrane layer, which is resistant to acids, alkalis, and various organic solvents, and is almost insoluble in all solvents. At the same time, the waterproof and breathable membrane is resistant to high temperatures. The waterproof layer 6 can prevent liquid from penetrating the outer layer and immersing the cable core 11 in liquid, causing leakage. The fireproof layer 7 is made of low-smoke halogen-free flame-retardant polyolefin material, thereby increasing the fire resistance of the cable. The tensile layer 8 is made of rubber material with elastic properties. In other embodiments not shown, the tensile layer 8 can also be made of nitrile elastomer.

[0024] Furthermore, multiple reinforcing strips 80 are provided within the tensile layer 8, and the multiple reinforcing strips 80 are arranged evenly and at equal intervals along the circumference of the tensile layer 8, thereby increasing the compressive strength of the cable.

[0025] Furthermore, the outer sheath 9 is also wrapped with a high-temperature vulcanized silicone rubber layer 90. The high-temperature vulcanized silicone rubber layer has good low-temperature resistance and can generally still work at -55℃. It also has outstanding heat resistance and can work for a long time at 180℃. In addition, it is wear-resistant and corrosion-resistant, making it a very good sheath material that can effectively protect the cable.

[0026] The low-temperature resistant and crack-resistant aluminum alloy cable provided by this utility model features a cold-resistant rod 3 installed inside the shaping component 2, with the cold-resistant rod 3 corresponding to the shaping component 2. The armor layer 5 is wrapped around the outside of the shaping component 2, and the anti-deformation rod 4 is placed between the shaping component 2 and the armor layer 5. The cold-resistant rod 3 has characteristics such as high strength, hydrolysis resistance, high resilience, and low-temperature performance, which enables the cable to have high mechanical strength, withstand large external forces without damage, and has good pressure resistance, thus protecting the cable core unit 1. At the same time, the cold-resistant rod 3 does not become too brittle or lose elasticity at low temperatures like other materials. The anti-deformation rod 4 has good tensile and deformation resistance, thereby enhancing the cable's toughness and reducing the phenomenon of cable bending and breakage.
