Metal tape forming and welding technology Following the demand of the industry for alternative solutions, and based on experience of successful projects in the field of metal tape forming, welding and corrugation for high-end RF cables, Rosendahl has entered this market segment. Cable manufacturers require this technology for cables for wind farms, offshore power stations or cables for submarine applications. The LV segment also includes a number of products (oil-pump, shipboard, signal cables), which use the Rosendahl technology to improve product properties or to increase productivity during the manufacturing process.

Compared to other technologies (aluminium or lead extrusion) the metal tape forming and welding system has several advantages. It shows better results for continuous operation, economic use of electric power and water, reduced scrap during production, dimension change and the possibility of using different metallic materials for shielding. Cables produced in this way are said to demonstrate superior mechanical stability and water and/or gas tightness. Technologies developed and optimised for these applications include welding processes – to ensure perfect weld seams with minimal heat affected zones and best mechanical properties, and high speed corrugators for helical and annular corrugation for copper, aluminium and stainless steel. For metal shielding by means of smooth or corrugated aluminium, copper or stainless steel, Rosendahl offers solutions for the tape forming, welding and tube reduction process including adequate down stream equipment. Depending on the cable design, space availability and product mix, Rosendahl is in the position to serve inline (in combination with the jacketing process) and offline solutions.
