Drum twisters up to 60T SETIC Pourtier is a designer and manufacturer of high-speed rotating machines for the cable industry. The SETIC brand is focused on special, data

communication and LAN cable machines, and automotive wire equipment. Pourtier develops heavy-duty rotating machines to produce all types of power cable: overhead, submarine, high voltage, and extra-high voltage. SETIC’s TC2600-4M is a high-speed large double twist (2,600mm) for cable makers stranding large bare conductors from 7 to 61 wires, in copper and aluminium, round or straight sector, in 61-wire uni-lay production (compressed and compacted) up to 400mm 2 (750MCM) Cu and 630mm 2 (1250MCM) Al. The line can also strand class 5/6 flexible conductor up to 240mm 2 (500MCM) and lay-up insulated conductors up 30mm (1.18") cable diameter. Pourtier’s “RFS” heavy-duty rigid strander line (630 or 800mm reel) is designed for stranding up to 163 wires with pulling capstan up to 80 tons, with steel wire armouring and copper wire screening. These types of lines strand bare copper, copper alloy, aluminium, and aluminium alloy conductors up to 5,000mm 2 . The drum twister designed by Pourtier integrates all parameters to fit with

the production requirements of high voltage and extra-high voltage power cable (Milliken) for laying-up of Cu or Al conductors. Drum twisters are specially designed for round or sector-shaped (straight or pre-spiralled), five or more cores and for HV Milliken cables – segmental or sectoral pre-spiralled Cu (five to seven cores). Pourtier supplies drum twisters up to 60T open cradle. SETIC and Pourtier also provide high speed dual single twist lines, with one single twist used as payoff and another as take-up, for different sizes of bobbins such as 1,000mm (39.37"), 1,250mm (49.21") and 1,600mm (62.99"), which offer three solutions in one line: full back twist laying-up line, and two separate laying-up lines (with the possibility to make cable in multi-passes using a central back-twist payoff). The SETIC “all in one” VTT560F offers double or triple twist process with integrated back-twist effect. VTT560Fs are fully operational across North America, in customers’ R&D laboratories.
