In view of the constant evolution in standards and design, the characteristics of the elements contained in this manual are subject
to change without prior notice. These characteristics, as well as the availability of components, are subject to confirmation by
Ormazabal.
CAUTION!
When medium-voltage equipment is operating, certain components are live, other parts may be in movement and some may
reach high temperatures. Therefore, the use of this equipment poses electrical, mechanical and thermal risks.
In order to ensure an acceptable level of protection for people and property, and in compliance with applicable environmental
recommendations, Ormazabal designs and manufactures its products according to the principle of integrated safety, based on
the following criteria:
• Elimination of hazards wherever possible.
• Where elimination of hazards is neither technically nor economically feasible, appropriate protection functions are
incorporated in the equipment.
• Communication about remaining risks to facilitate the design of operating procedures which prevent such risks,
training for the personnel in charge of the equipment, and the use of suitable personal protective equipment.
• Use of recyclable materials and establishment of procedures for the disposal of equipment and components so
that once the end of their service lives is reached, they are duly processed in accordance, as far as possible, with the
environmental restrictions established by the competent authorities.
Consequently, the equipment to which the present manual refers complies with the requirements of section 11.2 of Standard
IEC 62271-1. It must therefore only be operated by appropriately qualified and supervised personnel, in accordance with the

Gas tank
This is a sealed compartment, made of stainless steel and
sealed for life, which houses the switching and breaking
switchgear, with gas as insulating medium.
Depending on the function for which the cubicle was
designed, it may contain the following components:
• Disconnector.
• Earthing switch.
• Internal busbar and connections.
• Vacuum circuit-breaker.
• Switch - disconnector.
• Fuse holders.
Connection to the busbar is possible via upper bushings.
Connection to the medium voltage cables is made with the
lower and/or side bushings.
The gas pressure is tested, in each cubicle visually by means
of a pressure switch with a volt-free contact, allowing it to
be used as a remote alarm or blocking/trip for the position.
Figure 1.2. Example of bushing position in gas tank (1)
Busbar compartment
The busbar compartment, designed to withstand an
internal arc inside (optional), meeting the criteria of Annex A
of Standard IEC 62271-200, class IAC: AFL/AFLR, is located
at the top of the cubicle, separate from the gas tank. It is
made from metal sheet, offering the degree of protection
necessary for the connection device.
It comprises a fully assembled, tested unit, separated
by phases (segregating them as an option), by way of
earthed metal plates, with solid, screened insulation,
earthed through an earth collector plate specific to the
compartment.
Toroidal current transformers and/or plug-in voltage
transformers can also be installed, thus avoiding the need
for metering cubicles.

General description
Cable compartment
[2] There are four or six in the case of cubicles with rated branch current of 2500 A.
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. This compartment
is prepared to withstand an internal arc in terminals up to
31.5 kA - 1 s, meeting the criteria of Annex A of Standard
IEC 62271-200, class IAC: AFL/AFLR.
In the most complete case, the base can house the following
components:
• Phase segregation assembly (optional) consisting of the
main box and the segregating cover.
• Three[2] symmetrical shielded terminals with reinforced
connection (screwable) by phase or four asymmetric
ones.
• Clamp flanges for the medium voltage cables.
• Earthing bars.
• Toroidal current transformers.
• Voltage transformers, with connection via medium
voltage cable or plug-in/disconnectable.
All the elements making up the enclosure are earthed
by means of a conductor consisting of a copper plate,
sized to withstand the rated short-time current. This is
located in the base, meaning it does not need to be
dismantled in order to insert or remove a cable and its
corresponding termination.

in accordance with IEC Standards
Fuse compartment
[3] There are four or six in the case of cubicles with rated branch current of 2500 A.
The fuse protection cubicle cpg.0-f, has separate fuse
holders to house medium voltage limiter fuses.
The compartments are pipe-shaped and are fully enclosed
in the gas tank, making them unaffected by pollution. To
remove and insert the fuses in the fuse holder, a carriage
is used to simplify the operation and ensure correct fuse
placement.
The pipe seal consists of an elastic membrane with the
following functions:
• To ensure the water-tightness of the fuse holder
against flooding and thus avoid interior pollution and
degradation.
• Additional insulation to that provided by the fuse holder
carriage insulator.
• To transmit the movement of the fuse striker to the
tripping mechanism, while maintaining the water-
tightness of the fuse holder tube.
By the very nature of its construction, this sealed solution
is subject to the internal overpressure caused by abnormal
overheating of the internal air. In this case, the trip device
can act as protection against overheating, thus preventing
damage to both the fuse and the fuse holder.
Figure 1.5. Fuses compartment detail
Exterior cable connections (bushing)
The cpg.0 cubicles have bushings on the front for medium-
voltage cable connection. These are made of epoxy resin
and can, thanks to their configuration, withstand the
current transformers. They are duly screened and designed
in line with Standard EN 50181, being of type “C”.
They allow the connection of conductors of up to 800 mm2
via screw-in T-type connectors of any manufacturer. The
cable compartment allows the installation of up to three
cables[3] per phase, with a symmetrical terminal, or up to
four cables per phase, with an asymmetric terminal.

with full insulation in gas, up to 40.5 kV,
in accordance with IEC Standards
4. Handling and transport
4.1. Transport conditions
During transport, the switchgear must be perfectly seated
and fixed so that it cannot move about and possibly
damage the equipment. Always in upright position, un palé
directly on the ground or on a wooden pallet, depending
on the type of handling involved. Check that the cubicle is
perfectly balanced at all times.
4.2. Lifting means
The cpg.0 cubicles can be handled by lifting (with slings) or
with a forklift truck (with a pallet):

Storage General instructions
cpg.0: GIS-type medium-voltage switchgear
with full insulation in gas, up to 40.5 kV,
in accordance with IEC Standards
5. Storage
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, ensuring it is not damaged during
the storage period.
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.
Figure 5.1. Storage conditions detail
Storage must always be INDOORS, with the following
conditions recommended:
1. Ambient air temperature should not exceed 40 °C
and its mean value, measured in a period of 24 hours,
should not exceed 35 °C.
2. The ambient air temperature should not drop below
-5 °C. There are also cubicles with storage temperature
up to - 15 °C and up to - 25 °C.
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 notified beforehand,
since the equipment must be factory-adjusted to the
atmospheric pressure. Otherwise, the needle may indicate
an incorrect value (red scale), even though the value of
the equipment internal pressure is correct. Otherwise, the
manometer needle may indicate an incorrect value, even if
the equipment's internal pressure is correct.
