[0002] Cables are wire products used to transmit electrical energy, information, and convert electromagnetic energy, and are widely used in power, communication, transportation, and other fields. The tensile strength of a cable is one of its important performance indicators, directly affecting its service life and safe operation. Therefore, accurate testing of the tensile strength of cables is of great significance.

Therefore, we propose a cable tensile strength testing equipment. Utility Model Content
