Roll form strander The roll form stranding process from Ceeco Bartell combines the advantages of two highly productive processes – roll forming of shaped wire and double twist stranding of conductors. These two systems are forged to create one high-speed continuous manufacturing cell, capable of producing up to 300mm 2 compact conductors at speeds of over 200m/min.

Roll form stranding technology from Ceeco Bartell Products ❍ ❍

Roll form stranding not only produces compact strand at high speeds, but also allows significant savings to be made throughout the stranding process, from wire drawing to the extrusion process. Roll form strander allows the use of a single input diameter wire to be used throughout the stranding process, resulting in significant process savings and advantages, including: Higher productivity stranding (typically 40 ton/day compact Al) • Higher productivity wire drawing •

Less 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 standers with the Ceeco Bartell patented roll forming process is said to reduce costs without compromising finished conductor performance.

Rollertwist stranding Conductix Wampfler, of the Delachaux group, offers Rollertwist™ stranding tech- nology, originally developed through the Godderidge company. A Rollertwist unilayer strander will strand 1, 7, 12, 19 or 37 cables or wires at the speed of a double twist but with the quality of the single twist. Tapes can be applied if required.

Applications of Rollertwist stranding include: Data and LAN telecommunication cables • Control and signal cables •

Building and LV power cables • Hybrid and composite cables • Delachaux SA – France Fax : +33 479 425005 Website : www.conductix.com
