The main purpose of UV aging test for wire and cable is to evaluate its weather resistance and durability to determine its service life and performance stability in outdoor environment. Ultraviolet radiation, temperature change and humidity change in outdoor environment will have a negative impact on the material of wire and cable, such as causing material deterioration, perubahan warna, hardening, cracking and other problems.

The UV aging test enables a more accurate prediction of the performance of wires and cables in outdoor environments by simulating their exposure under actual conditions of use. The UV radiation source in the experiment can simulate the ultraviolet rays in sunlight, while the temperature and humidity changes simulate the temperature difference between day and night and the humid environment.

Melalui uji penuaan UV, the anti-UV performance, tahan cuaca, tahan panas, oxidation resistance of wire and cable materials can be evaluated to determine their reliability and service life in outdoor environment. This is of great significance to ensure that wire and cable can work safely and reliably under various climatic conditions, and also helps to formulate suitable product specifications and ensure product quality.
