A top rear entry power cable with gas duct is
also available as shown in 6/22.
Cable sealing ends are mounted on the cable cores
according to the manufacturer’s instructions.
It is possible to use cable sealing ends of different
manufactures (e.g. Pirelli, Raychem etc.), but it
is necessary to keep the length of the cable ends,
including cable sealing ends, a suitable match to
the length given by the distance of cable
connecting bars or tags (6/18) from the gland
plate (4/12).
The bars are equipped with M10 nuts. The earthing
of cable screens is carried out directly to the
earth bar adjacent to the cable entry position
in the floor.
It is possible to place three fixed mounted surge
arresters in the cable compartment. It is also
possible to install voltage indication bushings
here.

Onexthree-core 240 mm
