The choice between smooth and corrugated Corrugated metal sheaths are commonly used because of their high resistance and mechanical performance. In recent years, however, smooth bonded sheaths have become increasingly popular, in part because of their electrical behaviour and reliability. In addition, since no wave structure has to be taken into account, smaller cable diameters are possible. This is advantageous when replacing cables in existing pipework. Whether smooth or corrugated, helical or annular, and for terrestrial or sub-

It includes a non-stop in-line process for forming and welding cables with a cor rugated or smooth profile, including the monitoring of all system parameters. The welding electrodes alternate, if neces sary. While one is welding, the other can be exchanged or maintained. The line does not have to be stopped and production continues without waiting. Smooth aluminium sheaths can be produced if the line is used in tandem with the compacting unit and the triple extruder group. RH-W sheathes high- and extra-high voltage cables with a welding tube diameter of up to 200mm.

marine use, high- and extra high-voltage cables need to withstand physical and mechanical stress. A strong metal sheath makes sure they are constantly pro- tected, which ensures con- stant electrical conductivity. Rosendahl Nextrom’s RH-W metal tape forming and welding line is designed for the production of high- and extra-high-voltage cable.

CableMES operates in real time to enable the control of multiple elements of the production process. From order execution, production performance and material management through to product quality, CableMES integrates with other software solutions such as ERP and CableBuilder.

execute real-time cable production. In addition, CEOs and CFOs will be assured that the robust data supports business critical decisions. An MES bespoke to wire and cable manufacturing requirements presents a significant change in manufacturing. The vehicle for business processes allows continuous improvement throughout the manufacturing value chain.

Wire and cable design and manufactur ing software expert Cimteq, together with automation software provider Won derware by Aveva, has applied its 20+ year pedigree to developing CableMES. According to Cimteq, investing in MES (manufacturing execution systems) not only provides an almost immediate return on investment but also enables manufacturers to monitor, control and

Flat and shaped production equipment DEM provides equipment for the production of flat and shaped wire made from steel, copper or aluminium. The company’s technological packages for reinforcing wire rolling include:

and, with the support trolley, avoids the use of external lifting devices, improving operator safety • Automatic packaging solutions – fully automatic spool handling and transfer ring station with full/empty spool buff ering system, and full product tracking and interface with MES. DEM also provides fully automatic spoolers for compact coils, equipped with coil strapping/weighing and labelling units For flat and profile rolling, DEM can supply assisted threading systems, in line wire cleaning, and perfect layer winding – for wire as small as 1.5 x 0.2mm at speeds of 1,200m/min.

• Adaptive straightness control – auto- matic roll set-up for increased up-time, with in-line closed-loop control to produce straight bars • High-speed shear – to grant a speed of 5m/s for bars shorter than 2m, or 10m/s for longer bars. Top cutting speed of 150 cuts/min with a length tolerance of less than 1mm/m • Wire weight control – to roll wire to the lowest tolerance allowed by the standards by measuring the wire weight per metre in-line • Direct wire rolling – a capstan-free line solution for easy line threading. With automatic roll gap positioning and fast set-up, production change-over time is cut by 75 per cent • Quick cassette change – allows a cassette changeover in four minutes

The company also supplies technology for the fabrication of cold rolled or stretched reinforcing wire; for the calibration and annealing of IT spring wire; and for the forming of cored wire. Coilers, spoolers and bar bundle facilities complement the lines to collect the end products. In addition to full automation controls, DEM’s Wire Up digital platform is an IIoT package developed specifically for the wire industry. Augmented reality togeth er with advanced connection solutions allow for remote maintenance/commis sioning. DEM also supplies cassettes and auxiliaries for CRLs, and micro cassettes and tooling for drawing lines.
