The cable core passes continuously through the crosshead. A cooled insertion tube protects the cable core on entry to the crosshead, and rapid quench of the aluminium tube immediately after the die prevents thermal damage to the core. Downstream from the SheathEx machine the cable sheath is corrugated in-line and coiled onto large drums. The SheathEx process is a continuous (no stop marks), reliable (no weld) and cost e ective (cheap materials, low energy) method of sheathing high voltage power cables. SheathEx, Conform and Conklad are Registered Trade Marks of BWE Ltd. International patents have been led for the SheathEx process, SheathEx tooling system, machine arrangement, control method and induction heating technology that is employed. BWE Ltd – UK

➣➢➣

With over 60 years’ experience in the design and manufacture of rotating machinery for the production of power and telecommunication cables and steel ropes, Spanish company CM Caballé provides the cable industry with a wide array of stranding, twinning, bunching and cabling machinery.

The SheathEx production line

▲

The SheathEx machine incorporates a large crosshead to accommodate the large diameter dies required for cable sheathing. The aluminium sheath is seamless, with no weld line or bead. The twin groove mode of operation ensures the aluminium sheath is concentric. BWE’s patented induction heating system provides a very even temperature distribution around the tooling, leading to very stable running conditions, and consistent properties in the aluminium tube. The feedstock material is standard CCR aluminium rod, which is readily available and cheap, compared to other materials (such as at aluminium sheets used in a welding line).
