[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. They are composed of one or more insulating cores, and their own protective layers and outer sheaths. Wires and cables need to have high bending strength to prevent damage to the guide or insulation due to stretching or bending during use. Therefore, sampling inspection of wires and cables is required. During the laying process of cables and wires, sometimes they need to be bent back and forth many times due to direction adjustment. Therefore, cables and wires not only need to be resistant to bending, but the number of bending resistance is also one of the indicators of cables and wires.
