➣➢➣ technology is particularly suited to the production of high-purity oxygen-free copper wire rods and copper conductor alloy wire rods (eg copper silver, copper magnesium, copper tin), 1,000 to 10,000 tpa. This graphite furnace technology produces high-quality CuOF 8mm diameter wire rod, which benefits manufacturers of enamelled wire, LAN cables and fine wires. The upward casting equipment may be used to manufacture rods of all diameters between 8m and 30mm diameter and is suitable feedstock for wire drawing, as well as continuous rotary extrusion processes. End-use applications include super-fine wire, automotive wires, contact wire and trolley wires for high-speed trains, data communication cables, CTC and transformer strips as well as enamelled wires. Rautomead will also be promoting its new RSL sealed lid technology. This is a result of extensive research and development activity, which focuses on the casting capability for new high- performance alloys, in particular copper zirconium and copper chrome zir- conium. RSL casting machines have recently been supplied to customers in Europe and China. Rautomead Ltd – UK Website : www.rautomead.com ❍ The RSL 1400 sealed lid upwards vertical continuous casting machine Roblon will be presenting its latest developments in performance fibres and machinery in FOC applications. It will showcase a variety of performance fibres, as well as Roblon machinery applications. Roblon ultra low shrinkage binder yarns: the binder yarns are developed for fixating stranded optical fibres and/or Roblon A/S Stand: G32

folded tapes in optical cables. In a time where other premium binding materials are in scarce supply, the ultra low shrinkage binder yarn, with <0.25 per cent shrinkage, is a good alternative in critical applications such as high- density cables and mini-/micro-cable designs.

The company is also expanding its preform research and development centre in Vantaa. It will be expanded by VAD core deposition and core stretching technology, and by a glass working lathe to make it possible to do both VAD and OVD processes in house. The continuous development and improvement of extrusion, in order to meet the rapidly growing range of new extrusion materials, makes the ROEX extruders among the best on the market, the company states. Cables that are exposed to con- siderable and difficult environmental influences are insulated using special materials. For insulation and sheathing, materials are usually crosslinkable, halogen-free materials. Rosendahl Nextrom developed, and has been using for several years, machinery built for this purpose. The company’s technology centre also offers the opportunity to demonstrate the performance of a complete cable production line. Trials are possible on these lines as well.

The binder yarns are available both as dual-end and water-blocking versions. Applying binder yarns in critical cable designs involves not only a high-quality performance fibre, but equally important premium equipment capable of ensuring a low and constant yarn tension at high speed. Roblon offers single and dual-end binders for this purpose and is the only supplier offering both binder yarns and machinery. Due to this unique synergy, Roblon is renowned for its ability to optimise the binding process together with its customers. Roblon A/S – Denmark Website : www.roblon.com ❍ Roblon is showcasing a variety of performance fibres, as well as machinery applications The Rosendahl Nextrom team will be presenting the latest technology regarding fibre drawing and FOC manufacturing solutions, as well as the latest updates of the successful ROEX extruders and smart solutions for cable-manufacturing systems. Optical fibre production solutions: as a company for turnkey manufacturing solutions for optical preforms, fibres and fibre optic cables, Rosendahl Nextrom has a fibre draw line installed in-house in Vantaa, Finland. This enables on-site development to take fibre technology to the next level. Rosendahl Nextrom Stand: H01

Jacketing lines for MV and HV cables require high output and high precision of the jacket itself. Quality and valuable cables for MV/HV application, with diameters of over 150mm, require high material throughputs of 1,000-1,400 kg/h to achieve better performance. Larger tolerances on the outside diameter and/or wall thickness can very quickly generate much higher material costs. Rosendahl Nextrom offers stable extrusion output over the whole range of operation, which results in lower production costs while at the same time achieving higher performance. ❍ The latest technology will be on show from Rosendahl Nextrom
