2. Busbar compartment
3. Cable compartment
4. Gas pressure relief duct (optional)
5. Control compartment
6. Driving mechanism area

These are the compartments which house the switching
and breaking switchgear, where the insulating medium is
gas. There are 2 or 3 separate compartments:
SF
6
• 1 for each of the feeder disconnectors
• 1 for the circuit breaker and the earthing switch
These are sealed compartments, made of stainless steel
and sealed for life. They are designed and tested to
withstand an internal arc of up to 31.5 kA - 1 s.
Depending on the function for which the cubicle was
designed, it may contain the following components:
• Feeder disconnectors
• Earthing switch
• Internal busbar and connections
• Vacuum circuit breaker
• Switch - disconnector
• Fuse holders
Figure 1.2 Gas tanks of circuit breaker and disconnectors for
cpg.1-v2 cubicle
There are sets of bushings in the top and bottom of the
compartments for connection of the busbar and the power
cables respectively.

with a volt-free contact, for possible use as a remote alarm
or blocking/trip for the functional unit.
This is used for connecting cubicles. It has solid and
shielded insulation, earthed by means of the compartment's
specific earthing bar.
Cable compartment
As an option, the busbar is able to segregate the phases
by means of a set of earthed metal plates (metal-clad).
Toroidal current transformers and/or plug-in voltage
transformers can be installed in this compartment, thus
avoiding the need for metering cubicles.
In the most complete case, the base can house the
following components:
• Phase segregation consisting of the main box
and the segregating cover.
• Up to 4 screw-in shielded terminals per phase,
as well as space for the corresponding incoming
power cables.
• Clamp flanges for the medium voltage cables.
• Earthing plates.
• Toroidal current transformers.
• Plug-in voltage transformers.
• Surge arresters.
Figure 1.3 Phase segregation in the cable compartment
(optional)
Located in the bottom part of the cubicle, this has a cover,
interlocked with the earthing circuit, which allows front
access to the medium voltage cables.
All the elements making up the enclosure are earthed by
means of a conductor consisting of a copper bar capable
of withstanding the rated short-time current. It is located
in the base in such a way that it does not need to be
dismantled in order to insert or remove a cable and its
corresponding termination.

The cubicles must always be kept upright, directly on the
ground or on a pallet depending on the type of handling
involved.
The cpg.1 cubicles are fitted with four eyebolt-type
suspension points which can be used for handling the
cubicles with a crane; to do this, four slings or cloth straps
are used capable of carrying at least 2500 kg.
Check that the cubicle is perfectly balanced at
all times.
Once the cubicle has been sited as close as possible to
its final installation position, remove all four suspension
points from the cubicle.
on the ground or on a pallet, depending on the type of
handling involved. Check that the switchgear is perfectly
balanced at all times.
If a forklift truck is available, this should have a fork at least
2 m long and be capable of carrying at least 2500 kg.

5 Storage conditions
Storage conditions
21
If it needs to be stored, the equipment must be placed on
dry ground or on top of damp-proof insulating material, still
in its original packaging.
Figure 5.1 Storage conditions detail
After prolonged storage, clean all the insulating parts
carefully before commissioning the equipment. The
enclosure should be cleaned with a clean, dry lint-free
cloth.
Storage must always be INDOORS, with the following
conditions recommended:
1. Ambient air temperature should not exceed
40 ºC and its mean value, measured in a period of
24 hours, should not exceed 35 ºC.
2. The ambient air temperature should not drop below
- 5 ºC.
3. The switchgear must be protected from direct solar
radiation.
4. Maximum altitude is 1000 m.
5. The environmental air must not have any significant
contamination from dust, smoke, corrosive and/or
inflammable gases, vapours or salt.
6. The switchgear must be protected from the rain, and
the humidity conditions should be as follows:
a) The mean relative humidity value, measured over
a period of 24 hours, must not exceed 95%.
b) The mean water steam pressure value, measured
in a period of 24 hours, must not exceed 2.2 kPa.
c) The mean relative humidity value, measured over
a period of one month, must not exceed 90%.
d) The mean water steam pressure value, measured
in a period of one month, must not exceed
1.8 kPa.
7. During transport, vibrations caused by external
factors or seismic movements must be insignificant.
Any other conditions must be notied
beforehand, since the equipment must be
factory-adjusted to the atmospheric pressure
at the nal destination or during transport.
Otherwise, the pressure switch may indicate an
incorrect value, even if the equipment's internal
gas pressure is correct.
