Preheating with temperature control

Initially developed for Sikora’s Preheater, the Wire-Temp 6000 is also now available as a standalone version and for retrofitting to existing preheaters. The Wire-Temp 6000 determines the conductor temperature independently from the cross-section, the material, the line speed and the surface structure of the conductor. A big advantage over conventional systems is that the temperature measurement is made by means of a non-contact thermal image sensor in an infrared camera, which detects the conductor and provides accurate measurements with no need for calibration. The Wire-Temp 6000 is available for product sizes from 0.1 to 10mm and from 0.15 to 100mm. Various communication interfaces are available for the transmission of the measuring values to a Sikora processor system, the line control or a laptop. The universal interface module for connections to RS485, RS232, Profibus DP or industrial field buses such as CANopen, Ethernet/IP, DeviceNet, Profinet IO fulfils the demand. The interface module and all connection

With the Preheater 6000 TC (TC - Temperature Control), Sikora offers a solution for a precise conductor preheating, the basis for high-quality cable production. The Preheater 6000 TC is positioned before the extruder and preheats the wire by means of inductive heating up to 200°C. A controlling module controls the power of the Preheater 6000 TC depending on the conductor material, the conductor dimension, the line speed and the desired temperature. A non-contact infrared camera takes the temperature inside the Preheater. With the approach of the direct integration of a wire temperature measurement in the Preheater and the feedback to its power control, it is assured that the wire temperature is always at its desired level. The Preheater is available for a product diameter of 0.32 to 2.8mm (0.08 to 6mm²) and applicable for new lines as well as the retrofitting on existing lines. The system comes with all common interfaces such Ethernet, Profibus and Profinet as well as analogue ports. Category 8 for data Datwyler has developed ‘CU 8203 4P’, a compact S/FTP AWG23 cable which complies fully with the anticipated requirements of the new Category 8.2 as specified in the ISO/IEC draft. The new international standards for Category 8 copper cable and balanced cabling systems for 40 Gbit/s are currently being developed as Draft Standards IEC 46C/976/NP and ISO/IEC TR 11801-99-1. Unlike the proposed standards for symmetrical Category 8 data cables discussed a few years ago, the sole use foreseen by today‘s international standardisation bodies is in data centres with a maximum limiting frequency of 2 GHz. Standard ISO/IEC TR 11801-99-1 defines a point-to-point connection between active devices at a maximum distance of 30 metres, comprising 26 metres of installation cable and 2 metres of patch cable on either side. Such a connection can replace expensive fibre optic and twinax cabling in data centres. Datwyler Cables GmbH – Germany Website : www.cabling.datwyler.com
