Make your power cable production more energy efficient with polypropylene

Polypropylene, also known as polypropene or for the abbreviation PP, is a thermoplastic material used in many applications. One of its main features is that it can be fully recycled. It also has a lot of other advantages if you consider the whole product cycle and manufacturing process. Producing PP consumes around ten percent less energy compared to polyethylene (PE), traditionally used for power cable production. Using polypropene instead of cross-linked polyethylene (abbreviated as PEX, XPE, or XLPE) simplifies the entire line setup, as the complex crosslinking process is eliminated. That leads to significant energy reduction and a much shorter and more compact line layout: you can save up to 40% in length and up to 60% in height. In addition, PP makes it possible to dispense with energy-intensive degassing at the end of the production process, which also results in much shorter lead times.
All in all, if you're looking for ways to make your power cable production more energy efficient, you should consider polypropylene! Rosendahl Nextrom has put the material to the test and developed a whole manufacturing concept for it, with impressive results.


The R&D unit of Rosendahl Nextrom teamed up with HV Cable Solutions Ltd to test polypropylene-based compounds (PPC) in comparison with XLPE insulation material in medium-voltage cables. The Rosendahl’s RM-A line was used to produce a large volume of test cables. The results are outstandingly positive and verify the properties of PPC:

• Excellent electrical behavior (equal to or better than XLPE)
• Significantly reduced scrap rates
• Reduced operating costs and typically lower insulation system costs.
The perfect manufacturing concept for medium-voltage power cables

Rosendahl’s Superior Extrusion Technology (RoSET) is the perfect all-in-one solution for MV power cables up to 30 kV. It allows combining all the aforementioned advantages, saving a large amount of energy, which is no small feat at a time like this.
By choosing RoSET, you not only get a premium triple-layer insulation line, but also intensive process and material know-how and a PPC starter package to work with. On top of that, RoSET comes with a cable performance guarantee.
This energy-friendly technology will be one of Rosendahl's main attractions at wire 2022 in Düsseldorf. Make sure to visit stand no. A60 in hall 9.
