Design of joints
For cables without armour
The joint consists of four or five inner and
one outer heat-shrinkable tubing. The
connectors are insulated and sealed by
thick-wall tubings which are pre-coated
with a hot-melt adhesive. The outer
protection and sealing is performed by a
thick-wall heat-shrinkable tubing. All joints
are designed to allow crossing of cable
cores. For joints supplied without
connectors, the crimp or mechanical
connectors used must not exceed the
maximum dimensions given in the tables.
Dimensions L, D see table
For cables with steel tape armour
The joint consists of four or five inner and
one outer heat-shrinkable tubings as well
as tinned grid and roll springs. The
connectors are insulated and sealed by
thick-wall tubings which are pre-coated
with a hot-melt adhesive. Wrapped
around the jointing area, the tinned grid is
mechanically secured and electrically
connected to the steel tape by roll
springs. The outer protection and sealing
is performed by a thick-wall heatshrinkable
tubing. All joints are designed
to allow crossing of cable cores. For joints
supplied without connectors, the crimp or
mechanical connectors used must not
exceed the maximum dimensions given in
the tables.
