Description

Thermal aging test box for cable detection Technical Field The utility model relates to the technical field of cable detection, in particular to a thermal ageing test box for cable detection. Background The cable thermal ageing test aims at simulating the condition that the cable is heated for a long time in the actual use process, and the thermal ageing resistance of the cable material is evaluated by observing the appearance change, the mechanical property change and the electrical property change of the cable after thermal ageing, so that the safety and the reliability of the cable in various environments are ensured. The thermal aging resistance of the cable material was evaluated by observing and analyzing the aged cable samples. The cable is usually cut to a certain length and hung on a hook or a test rod in a thermal ageing test, and then a heavy object is fixed on the cable so as to keep the cable in a straightened state, but the heavy object is usually fixed in a binding mode when the cable is fixed, so that the fixing efficiency is lower.
