how, and fully trained and experienced technician support. H Folke Sandelin AB www.hfsab.com Inductotherm Heating & Welding will be highlighting its Radyne Spring Wire Line system at wire 2022. With a number of successful installations in wire producing companies, the system is distinctive in its use of a water quenching system rather than the more traditional oil method. The system provides environmental benefits and improved process control, as well as preventing dimensional distortions. Read the full story in the March issue line with the strander. This system, deployed with a Roteq single or double twist strander for production of single input wire (SIW) conductor, provides improved productivity with minimal work-in-progress (WIP). For stranding large compact and compressed copper conductors, Roteq offers concentric, single twist and double twist stranders. Roteq provides equipment, spare parts and field service from its facility near Toronto, Canada. Roteq Machinery Inc www.roteqmachinery.com Eder Engineering GmbH Eder drawing die-tool working machines allow users to benefit through longer life of dies and higher tonnage drawn; accurate reconditioning of the die; durability with minimal maintenance costs; lower operational cost; reduction of manpower (due to high degree of built-in automation); easy operation; and the experience and At wire 2022, Spirka Schnellflechter will exhibit a medium heavy braider in combination with a suitable winding line for heavier copper and steel wires. This braiding machine has an application range for cables up to 45mm and steel and copper wires up to 0.4mm diameter. It is suitable for thread tension up to 35 N, and can handle spools with a maximum flange diameter of 98mm. Read the full story in the March issue Inductotherm Heating & Welding Ltd

The latest design of fully automatic lead extruder from HFSAB is a horizontal floor- standing system that is easy to install and maintain, with a control system that enables continuous operation for weeks with little or no variation in temperature and wall thickness/concentricity. The lead wall thickness can be kept to a minimum with corresponding savings in Fil-Tec, Inc Fil-Tec, Inc offers a complete line of performance yarns for applications in power cables, copper and fibre optic telecom and speciality cables. Products on display at wire 2022 will include binder yarns with water-blocking, non-wicking, flame-retardant/low-smoke finishes; core yarns; rip cords; filler yarns; marker yarns;

lead. A range of die blocks cover diam- eters from 6 to 190mm (over lead), and melting pots are available for capacities of 10, 18, 35 and 60 tonnes. Additional equipment includes the CRRS (Cable Repair and Recovery System), which can remove individual layers, such as the outer jacket, lead sheath or triple layer XLPE insulation, without causing damage to the layer below. This allows the layer to be reapplied, and the cable repaired. Even if the cable is going to be scrapped, there are large differences in metal prices for insulated and un-insulated cables. HFSAB is able to provide upgrades, spare parts, extensive after-sales service, know-

and fibreglass reinforcement yarns. Read the full story in the March issue

Full range of rotating equipment Roteq Machinery Inc develops and manu- factures rotating equipment for wire and cable, umbilical and hose industries. Its portfolio of completed projects spans the full range of rotating equip- ment, including armouring, stranding, cabling and taping, and includes auxiliary equipment for complete production lines.

The company’s capabilities range from double twist tape shielding lines to 84" single twist machines, to optical cable stranding lines and auxiliary equipment. The next-generation V16 strip armouring machine, for the production of inter- locked armour on cables up to 50mm (2") in diameter, is claimed to provide manufacturers with improvements to overall equipment effectiveness (OEE). Machine operators experience easier set-up and pad changes, and a healthier environment. Preventive maintenance requirements are reduced while machine reliability is enhanced. manufacturers are offered Roteq’s technology for compact aluminium conductors made with individual strand roll forming in- Large conductor
