soldering gland
General
Paper-insulated lead-covered cables can be connected to load-
break switch and circuit-breaker panels up to 12 kV and to load-
break switch/fuse panels up to 12 kV. Load-break switch and
circuit-breaker panels are equipped with a terminal block with
locked cable entry ports. The terminal block has three
connection pins moulded into the cast resin insulation.
On load-break switch/fuse panels, the 12 kV connection pins are
directly below the fuse holders.

EMARK
For cables with an aluminium core (figure 3):
Eaton cable core clamps are only suitable for
connecting cables with a copper core.
There is a maximum free space measuring
Ø 40 x 110 mm for connecting cables with an
aluminium core by means of crimp cable
sockets, for instance.
Basically, any type of cable core clamp can be
used, provided it is within the permitted
dimensions when crimped.
