Ensuring purity of XLPE pellets A Chinese manufacturer and global supplier of XLPE HV and EHV power cables has been using the Purity Scanner Advanced from Sikora for quality assurance of high voltage cables in its production lines since 2017. years in the area of online diameter, wall thickness and eccentricity measurement. Wanbin Chen, president of Sikora China, commented, “We are all presently recognising an interesting evolution, whether regarding the new capabilities with the 5G network,

the electrification of cars or the careful use of natural resources for a healthy environment, which includes the substitution of coal and nuclear driven power plants by wind energy.” Sikora AG www.sikora.net

For some years, the company has also been active in the manufacturing of subsea cables and integrated, among others, the Purity Scanner Advanced for quality control. Reliability is the most important aspect when selling subsea cable. Typically, the company offers a warranty of a certain number of years for this type of cable. “We cannot take any chances at the production of subsea cables,” explains the plant manager. “Each production step needs to be safe. It starts with the compound that we use for the cable insulation. Accordingly, we have implemented an online quality control of the XLPE material.” The company relies on the Purity Scanner Advanced for inspection and sorting. By means of X-ray technology and optical cameras, the system detects contamination inside XLPE pellets as well as on their surface. Contaminated pellets are automatically sorted out. The Chinese cable manufacturer in- stalled the Purity Scanner Advanced in its submarine cable production line, and also equipped the system in another production line at the beginning of 2021 to ensure XLPE purity, high-quality final cable and customer satisfaction. Sikora has been cooperating with the Chinese company for more than 20 ❍ Sikora’s Purity Scanner Advanced, installed at a Chinese manufacturer of HV, EHV and subsea cables
