Description

Technical Field

[0001] The utility model relates to the technical field of cable processing and belongs to a cable fatigue detection device. Background Art

[0002] Cables consist of one or more insulated conductors covered by an insulating protective layer and are used to transmit power or information. There are many types of cables, including power cables, communication cables, control cables, electrical equipment cables, marine cables, and mining cables, depending on their purpose, structure, and material. Power cables are primarily used for transmitting and distributing electricity, while communication cables are used to transmit various signals, such as telephone, data, and video.

[0003] Cables are typically installed outdoors at a certain height, so they are often blown by strong winds, causing them to sway and sway. During this process, they are subjected to various stresses, including static stress, transient stress, and fatigue stress. Fatigue fracture is a common failure mode of cables. Fatigue testing can be used to assess the fatigue life of cables under specific stresses, thereby preventing fatigue-induced fracture accidents. Current cable fatigue testing projects are usually conducted using different test devices, which require multiple devices and have low test efficiency. In addition, existing cable specifications vary, and the test devices currently on the market cannot meet the requirements for testing cables of different specifications, resulting in low device applicability.
