Intelligent detection technology plays a key role in wire and cable quality control.
Non-destructive testing technology is an important part, such as X-ray detection technology. The principle is that when X-rays penetrate cable materials, different materials and structures have different degrees of absorption and attenuation of X-rays. The X-ray signal after passing through the cable is received by the detector and converted into image information. It can detect the conductor arrangement inside the cable, the uniformity of insulation layer thickness, and whether there are defects such as bubbles and impurities. For example, the X-ray detection equipment of YXLON Company in Germany can clearly present the internal structure image of the cable, and the detection accuracy reaches the micron level. The online quality monitoring system collects parameters such as the outer diameter, resistance, and capacitance of the cable in real time by installing multiple sensors on the production line. For example, the monitoring system of National Instruments (NI) in the United States uses high-precision sensors and data acquisition cards to transmit the collected data to a computer for analysis and processing. By establishing mathematical models and algorithms, the data is analyzed in real time. Once the parameters exceed the set range, an alarm is immediately issued and the production equipment parameters are adjusted. After some large wire and cable production enterprises adopt intelligent detection technology, the product qualification rate has increased by more than 25%, effectively reducing the generation of defective and waste products, and improving the economic benefits and market competitiveness of enterprises.
