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 300mm2 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.
