Description

Technical Field

[0001] The utility model relates to the technical field of cable sheath materials, and particularly relates to an aging test box for cable sheath materials. Background Art

[0002] Cable sheath material refers to the material used to wrap the outer layer of wires or cables. Its main function is to protect the conductors and insulation layers inside the cable from the influence of the external environment, such as moisture, chemical substances, ultraviolet radiation, mechanical damage, etc. At the same time, it also provides electrical insulation and fire protection performance. In order to evaluate and predict its performance changes and durability during long-term use, aging tests need to be carried out to ensure that the cable can operate safely and reliably under various environmental conditions.

[0003] Currently, during the use of existing test boxes, only a single material or sample group can be tested, and it is impossible to conduct comparative tests on different materials or different batches of the same material under the same environment at the same time. This limitation not only leads to low test efficiency, requiring repeated tests to collect data under various conditions, but also seriously affects the accuracy of test results due to the lack of immediate control samples, making it impossible to ensure the comparability of data and the objectivity of material performance evaluation. Therefore, this application provides an aging test box for cable sheath materials to meet the requirements. Content of the Utility Model
