Technical Field

[0001] The utility model relates to the field of cables, in particular to a cable capable of maintaining performance under low temperature conditions. Background Art

[0002] Low-temperature resistant cables are specially designed cables used to transmit power and data in low-temperature environments; these cables are able to maintain good performance under extremely cold conditions, ensuring the reliability of power and data transmission; the design of low-temperature resistant cables uses some special materials and structures to adapt to the requirements of low-temperature environments; for example, the insulation layer on the outside of the cable usually uses special polymer materials, which have good insulation properties and low-temperature resistance; at the same time, the conductor inside the cable also uses high-purity copper or aluminum materials to ensure conductivity at extremely low temperatures; in addition, low-temperature resistant cables are usually equipped with protective layers to prevent the cables from being mechanically damaged in low-temperature environments; these protective layers can be metal sheaths, polyvinyl chloride sheaths or other materials, depending on the conditions and needs of the cable; the application range of low-temperature resistant cables is very wide; for example, In scenarios such as polar regions, high altitude areas and cold chain logistics, low-temperature resistant cables can be used for power supply, communication and data transmission; in these environments, ordinary cables may become brittle or lose their normal functions due to low temperatures, while low-temperature resistant cables can continue to work and ensure the stability and safety of the system; in short, low-temperature resistant cables are special cables designed for low-temperature environments with good cold resistance and reliable transmission performance; they maintain the reliability of power and data transmission under extreme low temperature conditions and are widely used in various cold environments. When using low-temperature resistant cables, the method of adding an insulation layer is adopted to protect the internal structure of the cable. In order to ensure the structural stability of the cable, the various layers of the cable are closely connected. When the temperature changes significantly, thermal expansion and contraction will occur, resulting in a large interaction force between the various layers of the structure, which can easily lead to structural damage.

By setting the heat storage paraffin, the heat storage paraffin can be melted when the temperature is high to store excess heat, and when the temperature is low, the heat storage paraffin solidifies and releases heat, so as to supplement the heat of the cable conductor;

[0015] 3. By setting the filling material, on the one hand, the cable conductor can be protected and the strength and stability of the cable can be increased. On the other hand, the heat conduction of the heat conductive layer can be assisted. By setting the heat conductive layer, the outside of the cable conductor can be heat-conducted, so that the heat distribution on the cable can be even, and the cable can be prevented from being damaged due to uneven heating.
