Description

Technical Field

[0001] This utility model relates to the field of tensile testing machines, and in particular to a multifunctional ultra-long cable tensile testing machine. Background Technology

[0002] A cable tensile testing machine is a professional testing device used to test the tensile strength, breaking strength, elongation, yield strength, and other mechanical properties of linear materials such as wires, cables, ropes, and optical fibers. It is widely used in industries such as power, telecommunications, construction, aerospace, shipbuilding, and automotive to ensure that cable products comply with relevant national standards or industry specifications.

[0003] When conducting tensile testing on cables, the entire sample must first be cut into small segments before it can be sent to the testing machine for testing. Otherwise, if the product is too long, there is not enough space for testing. Furthermore, the results obtained from testing a segment cannot fully reflect the tensile performance of the entire cable. In addition, this testing method requires destroying the integrity of the sample. Therefore, a multifunctional ultra-long cable tensile testing machine is proposed. Utility Model Content
