Joints
Südkabel offers an extensive program
of joints for high and extra-high
voltage XLPE cables.
The joints are completely maintenance-free,
since they contain no
gaseous or liquid constituents
("solid joints").
Both straight-through joints with
through connections of the screen
and sectionalising joints with potential
isolation of the screen on each
side of the joint are used.
For better quality assurance of the
manufacturing and installation procedures,
prefabricated and pretested
joints are the preferred solution.
The sectionalising joints are suitable
for cross-bonding the screens or for
single-sided screen earthing of the
individual laying sections.
In 1993, Südkabel was the first company
to provide prefabricated, pretested
joints in the extra-high voltage
levels of 245 kV to 420 kV as well.
This tripartite joint type has more than
proved its outstanding reliability in
several projects on the 420 kV voltage
level.
