Greater efficiency with Ceeco Bartell’s roll form strander ▲ ▲
High-speed, continuous roll form stranding The roll form stranding process combines the advantages of two highly productive processes, namely: roll forming of shaped wire and double twist stranding of conductors. These two systems are forged together to create one high-speed continuous manufacturing cell, which is capable of producing up to 300mm 2 compact conductors at speeds of over 200m/min. This system not only produces compact strand at high speeds, but also allows significant savings to be made throughout the stranding process, from wire drawing all the way through to the extrusion process. The aim is to present a technological solution in the manufacture of compact conductors, which brings cost savings from the wire drawing process through the cabling and into the extrusion process. This is the use of the roll form strander, which allows the use of a single input diameter wire to be utilised throughout the stranding process, giving significant process savings and advantages, including:
Higher productivity at stranding machine (typically • 40 tonne/day compact Al) Higher productivity in wire drawing • Lower drawn wire scrap • Lower insulating costs • Lower capital investment • Improved return on investment • Quicker set-up • Reduced work in process • Shorter cycle times • Smaller input wire storage area • 75% more energy efficient than a typical rigid strander • The high performance of roll form stranders, coupled with the Ceeco Bartell patented roll forming process, will allow the cable manufacturer to reduce costs without compromising the finished conductor performance. An awareness of this and other new technologies, combined with enlightened specifications, will further enhance the development of strand design and the potential to optimise further the manufacture of stranded conductors.
