Continuous extrusion technology

previously supplied globally have been for a corrugated aluminium sheath – a reliable process from 2 x 12mm diameter aluminium rods. BWE now offers a SheathEx line for both corrugated and smooth aluminium sheaths. One of the first SheathEx customers worked with BWE to develop and convert its line for both corrugated and smooth. Extensive tests in tandem with the plastic extruder allowed the cable to bend and wind on a drum without kinking or damaging the sheath. Existing customers are able to retrofit their corrugated line with this new technology. The SheathEx process provides a continuous and seamless aluminium sheath with no weld. The aluminium sheath has good conductivity and environmental properties and is light in weight. The use of standard CCR aluminium rod keeps material costs low. BWE continues to develop new products and applications, including wire arc

BWE Ltd is a British engineering company specialising in continuous extrusion machines and cold pressure welders. Its Conform™ and Conklad™ continuous extrusion technologies are established in the non-ferrous, cable and tube industries. Typical applications for Conform include copper and aluminium rectangular wire (magnet wire for transformers), solid aluminium conductor (SAC for cables), copper busbar, trolley wire and other shaped conductors, round refrigeration tube, and multiport or PFC tubes in different alloys. Conklad technology is available for applications such as AS wire, OPGW, CATV, sheathed composite cores, reinforced aluminium wire and other products requiring an aluminium sheath or non-ferrous cladding. BWE’s SheathEx™ technology was first developed in 2005. The process is used for ‘seamless’ aluminium sheathing of high voltage cables. All machines

BWE specialises in continuous extrusion machines

additive manufacturing (WAAM), 3D printing, electric vehicles and precious metals. demonstrations are available at BWE’s headquarters in Ashford, Kent, UK. The company’s research and development department will consider and prove any new application prior to investment. BWE also manufactures and supplies a complete range of cold welders and dies for a fast and reliable solution to welding non-ferrous materials from fine wire to round rod.
