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).
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.
