gas
up to 36 kV in accordance with IEC Standard with rated current up to 800 A
Installation
4.8. Cable connections
[10]
[11]
The medium-voltage incoming and outgoing feeders are
linked to the transformer or, occasionally, other cubicles
via cables. These cables and the corresponding bushings
in the
cgm
.800 system cubicles can be connected with
connecting points, either IEC type or IEEE-386 compliant.
[10]
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.
[11]
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.
