Power cables Merging SZ with sheathing

Rosendahl has further developed its technologies to merge its system SZ technology (for stranding sector-shaped conductors) with a sheathing process, all in one line. The excellent result of the finished power cable can be observed on the take-up reel.

Using SZ technology, where no heavy mass is in rotation, the working principle is the same as in conventional helical stranding systems. The payoffs and take-ups stands in the line are stationary reelers, needing no special foundation. The non-rotating reeler also helps to improve the line efficiency due to a very fast and simple reel loading and unloading cycle. As the reel does not have to be transferred between the stranding and the sheathing process, time and space saving is guaran- teed. There is also no limitation for the size of take-up so a longer product length can be held on larger take-up reels. The advantage of non-rotating machinery provides a safe working area for operators and reduces maintenance.

Measuring cable cross-sections VCPS-01, from German company iiM AG, is a measuring device for large cross-section cable. It was specially developed for geometrical measurements on medium voltage and high voltage cables. The high resolution of the VCPS-01 enables precise measurement of thin semiconductor layers in cables with a large exterior diameter. Measurements can be made without difficulty on cross-sections with an exterior diameter of over 120mm.

The previous standard system, VCP-04, has also been equipped with a high resolution industrial camera (2560 x 1920 pixels) with 5 megapixels, but the recently developed VCPS-01 exceeds easily its predecessor. Its resolution is ten times higher than that of VCP-04. VCPS is useable either as a single device or as a complementary system to the standard models VCP and VCPB and is suitable for all kinds of tasks both in production and laboratory. FlexiMeasureCable, the software used for all VCP systems, makes it possible to connect the measuring devices of this series to a computer. Thus the entire measuring spectrum of exterior diameters between 1mm and 120mm can be covered, especially in the laboratory.

In order to find out which resolution is the most convenient, and best suits the needs of the cus- tomer, iiM AG carries out analyses of the measuring ability of cable samples. The resolutions determined this way are variably adjustable on the VCPS-01 and guarantee ideal precision within the shortest time. iiM’s VCPS-01 measuring device ▲ ▲
