Description

Technical Field

[0001] This utility model relates to the field of cable technology, and more specifically, to a cold-resistant cable. Background Technology

[0002] Cables are typically made of one or more insulated conductors (such as copper or aluminum) and an outer insulating protective layer. They are used to transmit electricity or signals from one place to another. Wires are usually simple in structure, consisting of a single or a few conductors; while cables are more complex, usually composed of multiple wires combined with a more robust protective layer.

[0003] When facing cold environments, existing cables use cold-resistant cables. Existing cold-resistant cables usually use special sheaths and insulation materials. Single-layer sheaths have poor cold protection and lack reinforcement of the internal structure, resulting in poor protection of the internal conductor when facing bending and external pressure, making them prone to damage.

[0023] Example:

[0024] Please see Figure 1-3A cold-resistant cable includes: an inner reinforcing layer 1, an inner shaping layer 2 sleeved on the outer wall of the inner reinforcing layer 1, and a plurality of side-segmented extensions 3 extending from the outer wall of the inner shaping layer 2; and a plurality of filling components, each of the multiple filling components including: a filling layer 6, an insulating sleeve layer 4, and a conductor layer 5. The filling layer 6 is disposed on the outer wall of the inner shaping layer 2, and the filling layer 6 cooperates with two corresponding side-segmented extensions 3. The insulating sleeve layer 4 is disposed inside the filling layer 6, and the conductor layer 5 is fixedly connected to the inside of the insulating sleeve layer 4.

[0025] In a specific embodiment of this utility model, the internal shape of the pipe is achieved through the inner reinforcing layer 1 and the inner shaping layer 2, and the filling components are separated by the side segmentation extension 3, allowing different conductor layers 5 to be placed separately. The filling layer 6 is filled according to different partitions, and the shielding layer 7 provides internal shielding. Finally, the internal shaping is completed by the armor shaping layer 8, making it circular. The cold-proof aramid yarn layer 9 provides internal cold-proof insulation, and the thermoplastic elastomer sheath layer 10 provides external protection and also provides preliminary cold-proof insulation. The overall wear resistance, corrosion resistance, flame retardancy, cold resistance, and pressure resistance of the cable are better, and the protection against bending and external pressure is also better, which is conducive to long-term use.

[0026] Specifically, a shielding layer 7 is provided between the outer walls of the multiple side-segmented extensions 3.

[0027] In this embodiment, the shielding layer 7 is used to shield the internal conductor layer 5 to prevent internal signals from radiating outward and interfering with other devices, and also to protect the internal signals from external electromagnetic interference.

[0028] Specifically, the outer wall of the shielding layer 7 is fitted with an armor shaping layer 8.

[0029] In this embodiment, the internal components are shaped by the armor shaping layer 8, that is, the filling layer 6 is shaped and fixed, while the compressive strength of the cable is enhanced.

[0030] Specifically, the outer wall of the armor shaping layer 8 is fitted with a cold-proof aramid yarn layer 9.

[0031] In this embodiment, the cable is filled with a cold-resistant aramid yarn layer 9 for cold protection, thereby enhancing the cable's tensile strength and internal structural stability.

[0032] Specifically, the outer wall of the cold-proof aramid yarn layer 9 is fitted with a thermoplastic elastomer sheath layer 10.

[0033] In this embodiment, the thermoplastic elastomer sheath layer 10 provides external protection, achieving both cold protection and outer sheath protection.

[0034] Specifically, the outer wall of the thermoplastic elastomer sheath layer 10 is coated with a polyurethane elastomer coating.

[0035] In this embodiment, the wear resistance of the thermoplastic elastomer sheath layer 10 is enhanced by a polyurethane elastomer coating.

[0036] Working principle: The internal shape of the conduit is formed by the inner reinforcement layer 1 and the inner shaping layer 2. The filling components are separated by the side segmentation extension 3, allowing different conductor layers 5 to be placed separately. The filling layer 6 is filled according to the different partitions, and then the shielding layer 7 provides internal shielding. Finally, the armor shaping layer 8 completes the internal shaping, making it round. The cold-proof aramid yarn layer 9 provides internal cold protection and heat preservation. The thermoplastic elastomer sheath layer 10 provides external protection and also provides preliminary cold protection and heat preservation. The overall cable has better wear resistance, corrosion resistance, flame retardancy, cold resistance, and pressure resistance. It also has better protection against bending and external pressure, which is conducive to long-term use.
