Monitoring melt
temperature
Ultratemp 6000 is Sikora’s latest development for the power
cable sector. It is a non-contact polyethylene melt temperature
measurement system, based on non-invasive ultrasonic tech-
nology. It is specifically tailored to the production of medium
voltage (MV) and high voltage (HV) XLPE insulated power
cables.
The system precisely measures the melt temperature during
production without influencing the melt flow properties,
as the ultrasonic sensors are positioned outside of the flow
channel. Melt shear heating effects do not occur.
Besides temperature measurement, the Ultratemp 6000
detects discontinuities in the melt. Early cross-linking
after screens, which may lead to ambers and scorches in
the polyethylene material, is avoided. The extremely high
measuring rate allows a fast response time as well as the
registration of small temperature variations.
Ultratemp 6000 is described as an important step for
further process optimisation and cost reduction during the
production of MV and HV cables.
