How stable is Computer Cable under different temperature conditions?

The stability of Computer Cable under different temperature conditions is an important consideration, which is directly related to the safety, life and performance of the cable.1. Normal use temperature rangeGenerally recommended temperature: Computer Cable should not exceed 60℃ in normal use. This is because although polyvinyl chloride material has a certain heat resistance, long-term use in high temperature environment may cause accelerated aging of the material and performance degradation.Extreme temperature: Although the chemical properties of polyvinyl chloride indicate that its temperature tolerance range can reach 90℃, in actual applications, in order to ensure the safety and stability of the sheath, it is usually not exposed to an environment close to or exceeding this temperature.2. Stability in high temperature environmentShort-term high temperature exposure: In a short period of time, Computer Cable can withstand an environment slightly higher than the normal use temperature, but long-term exposure should be avoided to prevent thermal decomposition of the material or performance degradation.Long-term high temperature impact: When used in a high temperature environment for a long time, Computer Cable may soften, deform, crack, etc., which seriously affects the insulation performance and mechanical strength of the cable.3. Stability in low temperature environmentCold resistance: Computer Cable has excellent cold resistance and can be used in low temperature environment of -180℃. Under low temperature conditions, the sheath material can maintain good flexibility and mechanical strength, and is not prone to brittleness or breakage.4. The impact of temperature changes on stabilityTemperature fluctuations: Frequent temperature changes may cause changes in the internal stress of Computer Cable materials, and long-term accumulation may have an adverse effect on the stability and life of the material.Thermal expansion coefficient: The thermal expansion coefficient of polyvinyl chloride is relatively large. When used in an environment with large temperature changes, it is necessary to consider the matching gap between the sheath and other parts of the cable to avoid performance problems caused by thermal expansion.Computer Cable has good stability and reliability within the normal use temperature range (generally not exceeding 60℃). However, long-term use in high temperature environment may cause accelerated material aging and performance degradation; while in low temperature environment, it can maintain good flexibility and mechanical strength. Therefore, when selecting and using Computer Cable, it is necessary to make reasonable selections and designs according to the specific use environment and conditions to ensure the safety and stability of the cable. At the same time, during use, it is also necessary to pay attention to avoid the impact of frequent temperature changes and excessive thermal stress on the sheath material.
