Unveiling Overhead Power Cables: High-Temperature Resistance

Overhead power cables are a crucial component in the aerospace field, carrying the important task of transmitting power and signals. They operate in extreme environments such as high temperatures, low temperatures, vacuum, and radiation. Therefore, they need to have excellent high/low-temperature resistance and chemical corrosion resistance. So, what is the secret behind overhead power cables? In this article, we will delve deep to uncover the mystery behind them.

Components of Overhead Power Cables

Firstly, high-temperature cables consist of three parts: the conductor, insulation material, and sheath. The conductor is usually made of copper to provide good electrical conductivity; special sheath and insulation materials, such as silicone and fluoroplastics, are used. These materials have excellent high-temperature stability and corrosion resistance. They can maintain good electrical conductivity and insulation performance at high temperatures, ensuring that the cable can work stably and reliably.

The Structural Design of Overhead Power Cables is Crucial

The cable's interior uses special isolation layers and protective layers that effectively block the erosion of high-temperature environments on the cable. Meanwhile, the external sheath material of the cable has good fire resistance, which can effectively prevent the spread of fire, ensuring the safe operation of spacecraft in high-temperature environments.

The High Reliability and Long Life of Overhead Power Cables

Overhead power cables also need to meet the requirements of high reliability and long life. To ensure that the cable can still work normally in long-term high-temperature environments, it needs to undergo stringent quality control and testing during production and testing processes. Fine monitoring and strict control at each stage ensure that the performance of high-temperature cables meets expectations and can remain stable during prolonged use.

Precautions When Using Overhead Power Cables

When using overhead power cables, we need to pay attention to some details. Firstly, avoid exposing the cable to high-temperature environments for long periods to prevent damage to the cable's performance. Secondly, when connecting the cable, make sure to follow the correct wiring and connection methods.

In conclusion, overhead power cables, with their unique high-temperature resistance and stable performance, provide reliable assurance for the safe operation of spacecraft, offering strong support for humanity's exploration of the universe and realization of flight dreams.
