Stability of indoor and outdoor leather cables in extreme temperature environments

Publish Time: 2023-11-27
With the continuous development of science and technology, the demand for cables in electric power, communications and other industries is getting higher and higher. In this context, indoor and outdoor leather cables, as a cable product widely used in various scenarios, have received widespread attention for their performance stability.

1. Basic concepts of indoor and outdoor leather cables

Indoor and outdoor leather cables are cables with a protective layer and are mainly used to transmit power, signals and other energy. Its structure includes conductors, insulation layers, sheaths and other parts. The conductor is responsible for transmitting electrical energy, the insulation layer ensures that the current flows along a predetermined path, and the sheath protects the cable from damage by the external environment.

2. The impact of extreme temperatures on indoor and outdoor leather cables

⑴High temperature environment: High temperature will cause the insulation layer and sheath material of the cable to age, thereby reducing the performance and service life of the cable. In addition, high temperature may also cause partial discharge inside the cable, further affecting the stability of the cable.

⑵ Low temperature environment: Low temperature will harden the insulation layer of the cable, resulting in a decrease in the bending performance of the cable. At the same time, low temperature may also cause the moisture inside the cable to condense and form ice crystals, thereby damaging the structure of the cable and affecting its normal use.

3. Stability of indoor and outdoor leather cables in extreme temperature environments

In order to ensure the stability of indoor and outdoor leather cables in extreme temperature environments, manufacturers usually adopt the following measures:

⑴Choose high-temperature or low-temperature-resistant materials: For example, polyvinyl chloride (PVC) is used as the sheath material, which has good high-temperature and low-temperature resistance and can work normally in an environment from -40°C to 70°C.

⑵ Optimize the design of the insulation layer: Improve the heat resistance and cold resistance of the cable by increasing the thickness of the insulation layer or using special insulation materials.

⑶Adopt special production technology: for example, using radiation cross-linking technology to make the insulation layer of the cable have better heat resistance and cold resistance.

⑷ Strengthen sheath protection: By increasing the thickness of the sheath or adopting a double-layer sheath structure, the anti-aging performance of the cable can be improved and its service life can be extended.

In short, the stability of indoor and outdoor leather cables in extreme temperature environments depends on their material selection, insulation layer design and production process. By using high-temperature or low-temperature-resistant materials, optimizing the design of the insulation layer, adopting special production processes, and strengthening sheath protection, the stability of indoor and outdoor cables in extreme temperature environments can be effectively improved to meet the application needs of different scenarios.
