One versatile metal shielding technology for many applications
What if you could process copper, aluminum, stainless steel, and alloys, all on the same production line? With Rosendahl’s powerful RH-W metal tape forming and welding line, you can do just that. No need to limit yourself to one metal anymore. That opens up many possibilities for high and extra-high voltage cable manufacturers.
The extremely versatile metal shielding technology provided by Rosendahl covers a very wide range of product designs. Basically, almost every cable that needs protective metal shielding can be produced on the original Rosendahl RH-W metal tape forming and welding line. The fields of application are just as wide-ranging: land, submarine or underground use, renewable energy systems, interconnectors, ducts, and more.
Original Rosendahl technology for high-voltage and extra-high-voltage cable production
High und extra-high-voltage cables must definitely withstand physical and mechanical stress perfectly. That’s where high quality pays off. A strong metal sheath makes sure the cables are constantly protected, and electric conductivity is always guaranteed.
What exactly does the RH-W metal tape forming and welding line do?
In short, it includes a non-stop inline process for forming and welding high or extra-high-voltage cables with a corrugated or smooth profile, including the monitoring of all system parameters. The term ‘non-stop’ refers to welding. The welding electrodes alternate, if necessary. While one is welding, the other can be exchanged or maintained. Continuous production is crucial for an efficient production flow and this enhancement has elevated the manufacturing process to a new productivity level. The line does not have to be stopped and production continues without waiting. If in tandem with the compacting unit and the triple extruder group, it is able to produce smooth aluminum sheaths of outstanding quality.
Which cable diameter is the line able to process?
It sheathes high and extra-high-voltage cables with a welding tube diameter of up to 200 mm. The production of such a cable is very demanding, since the cable is, on the one hand, large and heavy and, on the other hand, has to meet certain requirements, such as a high resistance to lateral pressure, which is achieved by corrugation. Copper, aluminum, and stainless-steel tapes are preferably used for the metal sheath. For different dimensions you can make use of the quick-change mechanism for tools and enjoy its easy, safe and repeatable handling.
To whom is this line of interest?
Basically, to every cable manufacturer who produces high or extra-high-voltage cables and wishes to get the key processes (forming, welding and extrusion) from one source. That contributes to all the line processes being perfectly coordinated and optimized. And whatever your individual quality requirements are, Rosendahl Nextrom has got you covered. After all, tailor-made solutions are the company’s specialty.
