The higher the quality inspection department in a wire and cable enterprise, the better the quality of the wire and cable produced by the enterprise and the more trustworthy it is. So what kind of cable is of good quality? What are the quality inspection indicators? The following ECCA Manufacturer(XINYU-ENAMELEDWIRE) http://www.xinyu-enameledwire.com/
will give you a detailed introduction.
1. Conductor DC resistance measurement:
Conductor cores of wires and cables mainly transmit electric energy or signals. Conductor resistance is the main index to measure its electrical performance. When AC voltage is applied, the core resistance is larger than DC voltage due to skin effect and proximity effect, but when the power frequency is 50hz, the difference between core resistance and DC voltage is very small. At present, the standard can only require whether the DC resistance or resistivity of the detection... less
