1 . Application of the device the Application of The Equipment :
1.1 This test machine complies with the provisions of UL817 and other relevant standards ” General safety requirements for communication cords and power cords ” . It is suitable for the relevant manufacturers and quality inspection departments to carry out bending tests on power cords, DC cords and flat cables. This machine is in conformity with the provisions of the standard requirements of the “UL817” communication cords and power supply cords general safety. This product is suitable for manufacturers and quality inspection departments on the power line, DC line, cable, bending test.
1.2 The testing machine can monitor the real-time change value of the resistance of the wire sample, and can be controlled according to the upper and lower limits of the resistance set in advance. When the sample is damaged due to bending and the impedance exceeds the upper or lower limit, the group of counters stops counting, and It can be set that when the resistance of a single group or six groups exceeds the upper and lower limits, the whole machine will automatically stop operation. The testing machine can monitor the real-time variation of wire resistance of the samples, and can according to the preset resistance limits to control, when the specimen is bent and damaged lead impedance over the upper or lower limit, the group counter stops counting, and can be set to a single group or the six group resistance all beyond the upper and lower limit, the machine stops automatically operation.
