Ensure the highest XLPE purity

The well-known Chinese cable manufacturer installed the “Purity Scanner Advanced” in their submarine cable production line and at the beginning of this year also equipped the system in another production line to ensure the highest XLPE purity and a high-quality final cable.

A large and very successful 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 their production lines, since 2017. The Chinese company has been ranking among the top 10 competitive enterprises in the cable industry for many years. For some years, the company has also been active in the business of manufacturing subsea cables and integrated among others the scanner for quality control in its production lines. Reliability is the most important aspect, when selling subsea cable. Typically, the company offers certain years of warranty 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”, he concludes, whereby the company relies on the Purity Scanner Advanced for inspection and sorting. By means of X-ray technology and optical cameras, the system reliably detects contamination inside XLPE pellets as well as on their surface. Contaminated pellets are automatically sorted out.

Sikora is proud to be a partner of the Chinese global player also in this important project. Both companies have already been cooperating for more than twenty years in the area of online diameter, wall thickness and eccentricity measurement. “We are all presently recognizing 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. The company is in this respect a pioneer and Sikora the matching partner”, a statement that is underlined by both the Chinese cable manufacturer and Mr. Wanbin Chen, President of Sikora China.
