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.
