AI Technical Summary
Existing cable thermal aging testing devices are difficult to adapt to cables of different specifications, have poor temperature uniformity inside the chamber, and provide inaccurate data. Furthermore, the influx of cold air from outside causes a sudden drop in temperature, affecting the accuracy of the test.
A cable thermal aging testing device was designed, comprising an aging chamber, partitions, a blower, and a sealing door. The device achieves uniform heating by setting up a hot air channel, heating pipes, and a blower inside the aging chamber, improves sealing by using a sealing door and observation glass window, uses high-temperature resistant gloves to read data, and is equipped with an annular plug and a limiting mechanism to accommodate different cable lengths.
It enables compatibility with cables of different specifications, ensures temperature uniformity and detection accuracy, avoids the influence of external cold air, and provides accurate data reading.
