The “Sheath Ex” process provides a continuous and seamless aluminium sheath with no weld. The aluminium sheath has good conductivity, ideal environmental properties, light in weight and proven reliability. By using standard CCR aluminium rod, the material costs are very low, making Sheath Ex a very cost effective method of sheathing medium, high and extra-high voltage power cables.

BWE Ltd is a British engineering company specialising in continuous extrusion machines and cold pressure welders. “Conform” and “Conklad” are well-established continuous extrusion technologies 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 Bus Bar, Trolley Wire and other shaped conductors, Round Refrigeration Tube, 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 similar products requiring an aluminium sheath or non-ferrous cladding.

BWE continue to develop new products and applications including Wire Arc Additive Manufacturing (WAAM), 3D printing, Electric Vehicles and Precious Metals. Proving trials and demonstrations are available at BWE’s headquarters in Ashford, Kent, England. BWE’s research and development department will consider and prove any new application prior to investment. BWE also manufacture and supply a complete range of cold welders and dies for a fast, cost-effective and reliable solution to welding non-ferrous materials from fine wire to round rod. A range of machines will be on display and available for demonstration.
