4.8. Cable connections
[10]
It is advisable to use fully insulated connectors for voltages of 24 and 17.5 kV, according to HD 629.
The medium-voltage incoming and outgoing feeders are
linked to the transformer or, occasionally, other cubicles
via cables. These cables and the corresponding bushings
on the
cgmcosmos
system cubicles can be connected with
simple (plug-in) or reinforced (screw-in) connecting points,
either IEC type or IEEE-386 compliant.
The cable compartment contains the connecting cable
bushings for the incoming and outgoing feeders, as well as
for the outgoing feeders to the transformer.
The size of the cable compartment allows the use of both
insulated and partially insulated cable connectors.
[10]
Never touch live connectors, not even screened
connectors. Screening does not constitute a protection
against direct contact.
When the equipment is in service and a reserve cubicle
is left with voltage in the upper busbar and without
the cables in the bottom bushings, insulating plugs
must be placed in the bushings (EUROMOLD type) or
close the earthing switch and lock that position with
a padlock.
The recommended terminations are described below.
