At the world's leading fair for the wire and cable industry, the WIRE 2014, SIKORA will be presenting a broad product range of innovations as well as proven technology for quality control and cost saving at the wire and cable production.
The highlight at SIKORA’s booth is the newly developed PURITY SCANNER. The PURITY SCANNER is a system for the online inspection and sorting of plastic pellets used for the insulation of medium-, high- and extra-high voltage cables, but as well for other applications such as the medical industry. Contaminated pellets are separated and blown out, assuring that only pure pellets get into the extrusion process. The pellet inspection allows the detection of organic and metallic contaminations inside the pellet as well as on the pellet surface, using a special combination of X-ray technology and an optical system. The smallest detectable particle size is 50 µm at a flow rate of up to 2,000 kg/h.
LASER Series 2000 and 6000
In addition to SIKORA’s successful diameter gauges of the classic-line LASER Series 2000, SIKORA offers the top-line LASER Series 6000. These diameter measuring devices are specifically designed for sophisticated customer requirements that exceed the classic demands in the wire and cable industry. The gauges fulfill all needs regarding high accuracy, a variety of interface connection options and utmost reliability for a quality control at its best during wire and cable production. The high accuracy allows in addition the detection of lumps and neckdowns. Three gauges are available for different product diameters from 0.2 to 78 mm.
PREHEATER 6000 TC
Another attraction at the SIKORA booth is the PREHEATER 6000 TC (Temperature Controlled), which represents the optimum solution for the controlled preheating of conductors and sets the basis for the production of a broad cable type array at highest quality. The system heats the conductor inductively up to the nominal value. An infrared camera measures the wire temperature at the outlet of the PREHEATER wheel. A control module supervises and controls the power setting of the device with high accuracy, assuring that the conductor temperature always has the specified temperature. The PREHEATER TC is available in three power classes (10, 20, 30 kW) for preheating temperatures of up to 150 °C (optionally 250 °C), for a product diameter from 0.32 to 2.8 mm.
SIKORA also showcases the new WIRE-TEMP 6000, a system for continuous online temperature measurement of metallic and insulated conductors on a non-contact basis. The WIRE-TEMP 6000 had originally been designed as part of the PREHEATER 6000 TC. Now, it is also available as an independent device. As the temperature measurement is done by means of a thermal image sensor in an infrared camera, the conductor is always reliably detected with its wide measuring range. The system covers product diameters from 0.1 to 10 mm and 0.15 to 100 mm.
In addition to the latest technological highlights, SIKORA shows among others the TIGER LASER 6010 XY for diameter measurement and simultaneous lump detection, as well as the 2- or 3-axis lump detectors LUMP 2000 XY/T. For online quality control and optimization of the material usage for increased productivity during the extrusion, SIKORA offers the well-proven X-RAY 6000 for single-layered cables and the X-RAY 6000 PRO for multi-layered products. The X-RAY 6000 series is interesting for the continuous measurement of the diameter, wall thickness, eccentricity and ovality in wire and cable production lines. In combination with the processor system ECOCONTROL 600, 1000 or 6000, an automatic control of the line is possible.
SIKORA also exhibits the X-RAY 8000 NXT for quality control during the production of MV, HV and EHV cables in CCV-, VCV- and MDCV-lines. The X-RAY 8000 NXT has been delivered now a thousand times, and is recognized as an industrial standard. It is used for precise measurement of the wall thickness of all 3 layers (concentricity, diameter and ovality). Measuring values for centering and control are therefore available immediately after starting up the line.
