Advert: Polypropylene-based insulation technology for MV cables

November 2019 — “RoSET”, Rosendahl Superior Extrusion Technology, is a unique MV PPC cable-manufacturing concept for up to 30/36kV power cables. It consists of a dedicated MV line-type RM-A , PPC MV insulation, semi-conductive materials and know-how package.   

Over the past few years, thermoplastic polypropylene-based power cable insulation systems have gained a lot attention in the global cable industry due to their excellent electrical behavior and production benefits. Polypropylene-based compounds, or PPC, are also called HPTE, high performance thermoplastic elastomer materials, in some contexts. 

XLPE, silane and peroxide cross-linkable polyethylene insulation material, has already been dominating the power cable insulation material market for decades in land AC applications, and for roughly a decade in HVDC links. Now, polypropylene (PP) provides an equal or better alternative to XLPE. In polymer markets, polypropylene is the second-largest polymer after polyethylene (PE), with an annual usage growth rate of around 5-6%, and is therefore a raw material available globally.

“RoSET” – Rosendahl Production Line, Material and Know-How for PPC MV Power Cable Production
Rosendahl’s R+D intensely investigated and tested PPC against in comparison with the well-established XLPE insulation material in medium voltage cables. A number of test cables were carried out using our RM-A line in real manufacturing conditions. The results are outstandingly positive and verify the advantages of PPC in many aspects. To Rosendahl it was evident to bundle the gained know-how and offer it to power cable manufacturers globally under the name RoSET.
