Short interruptions of the inner semiconductor (strand shield) during production of medium voltage cables are abnormal occurrences that can occur periodically in very thin insulation layers. In the best-case scenario they are detected at a discharge test. However, if such faults are detected by the end-user the costs are tremendous. With the Strandshield 2000 Sikora has developed a system to detect and report any short interruptions of the semiconductor during the cable production process. With this method, the measuring system is installed in a separate short cooling trough after the CV-line. It detects the shortest interruptions with a length of 100mm. The Strandshield 2000 is a useful tool for quality control on the production line. Uninterrupted production lines

Achieving higher speeds In line with the philosophy of continuous improvement at PS Costruzioni, the engineers at PS have been working on improving production speeds.

Automatic coiling line, model PS 470/16, handles NYM cable from 2x1mm 2 up to a maximum of 4x6mm 2 . The first goal of the engineers was the increase in linear speed. Compared to the previous PS 470/16, linear speed has been increased by 15% (to 20,000 metres per hour). The machine will now produce 3.35 x 100m coils of 5x2.5 NYM cable.

Improved PS 200/6-B now spools 25% faster m m

The second goal was to reduce the need for mechanical maintenance. To achieve this the main motor has been installed in axis with the winding plates. This removes the need for mechanic transmission, and consequently less maintenance is needed. The double head automatic spooling line, model PS200/6-B, handles cable within the range of 16AWG to 10AWG. Again, the goal was to increase the linear speed. The line now produces 4 x 152m spools per minute for 12AWG (the equivalent of 36,500m per hour), which means that linear speed has been increased by 25% compared to the previous PS 200/6-B.
