Description

Technical Field

[0001] The utility model relates to the technical field of cable detection, in particular to a cable detection device. Background Art

[0002] Cables are large-diameter and long devices used to transmit electrical energy. Usually, they are not replaced or maintained for a long time after installation. Therefore, it is very important to fully ensure the reliability of cables before installation. Therefore, it is necessary to conduct various tests on cables, including electrical performance test, insulation performance test, appearance test, mechanical performance test, etc.

[0003] The mechanical properties test mainly tests the cable's tensile strength, compressive strength, abrasion resistance, tear resistance, impact strength and other indicators. The testing methods include static tests, dynamic tests and so on.

[0004] In tensile strength testing, the cable is usually fixed on a tensile testing machine, and then the tensile testing machine is used to test the changes in the cable's shape after being stretched and the ultimate tensile force it can withstand. However, traditional tensile performance testing usually tests the stress of the cable when it is stretched in a straight line, while in actual use scenarios, the laying of cables is usually tortuous, so when it is stretched, the stress at the corners is often greater and more complex, and it is also the weakest part of the insulation layer. Therefore, it is necessary to design equipment that can detect the changes in the cable's bending when it is stressed. Utility Model Content
