Advanced production for high voltage ❍ RH-W metal tape forming and welding line

torch TIG welding system to allow an electrode change during production. An automatic weld seam tracing system keeps the torches directly over the gap to achieve best welding quality. The innovative design of the split clamp catterpillar enables the highest pulling forces and an adjustment of the clamping pressure with a very short construction length. The RH-W produces smooth and/or corrugated products at high speed for helical and annular design. For different dimensions, a quick change mechanism for tools as well as easy, safe and repeatable handling, has been catered for.

considered as submarine power cables such as dynamic cables for floating platforms with corrugated copper sheath or as power cables for renewable energy such as export cables for offshore wind farms and cables for photovoltaic power plants. It is obvious that high precision work was the core value when designing this production line. The semi-automatic tape preparation equipment ensures the best tape treatment for the forming and welding process. One of the main targets was to develop a cost effective solution for tools and to cover a huge product range with reduced tool costs, which is possible with Rosendahl and Nextrom’s highly flexible and precise hybrid forming station. The companies were also aware that continuous operation is a must have, and therefore installed a double dual

RH-W stands for Rosendahl Nextrom high voltage forming and welding line, all in one – for either offline or inline production in a tandem process. Rosendahl Nextrom provides a high quality and advanced production line for large dimensions up to 200mm core diameter. The line and all its production steps meet the high level of demand and flexibility a cable manufacturer requires. Focusing on the application of HV cables, a flexible solution is the future in the HV cable industry. HV power cables are used for chemical plants, refineries, mines and factory environments and there are designs for dry locations, indoor as well as outdoor, direct buried or conduit installation. Other special applications can be
