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

General description General instructions
cpg.0: GIS medium-voltage switchgear,
gas insulated, up to 40.5 kV,
in accordance with IEC Standard
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 the insulating medium.
Depending on the function the cubicle was designed for, it
may contain some of the following components inside:
• Disconnector.
• Earthing switch.
• Internal busbar and connections.
• Vacuum circuit-breaker.
• Switch-disconnector.
• Fuse holders.
Connection to the busbar is possible via top bushings.
Connection to the medium-voltage cables is made with the
bottom and/or side bushings.
The gas pressure is tested in each cubicle by means of a
temperature-compensated 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 sheet metal, oering the degree of protection
necessary for the connecting device.
It comprises a fully assembled, tested unit, separated by
phases, by way of earthed metal plates, with solid, screened
insulation, earthed through an earth collector at bar
specic to the compartment.
Toroidal-core 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 outgoing 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 cable connectors
up to 31.5 kA - 1 s, meeting the criteria of Annex AA 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 screened cable connectors with
reinforced connection (screwable) by phase or four
asymmetric ones.
• Cable clamps for the medium-voltage cables.
• Earthing bars.
• Toroidal-core current transformers.
• Voltage transformers connectable through medium-
voltage cable or plug-in/disconnector.
All the elements making up the enclosure are earthed
by means of a conductor consisting of a copper at
bar, 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.

General description General instructions
cpg.0: GIS medium-voltage switchgear,
gas insulated, up to 40.5 kV,
in accordance with IEC Standard
Fuse compartment
The cpg.0-f fuse-protected cubicle has independent fuse
holders to house limiting medium-voltage fuses.
The compartments are pipe-shaped and are fully positioned
in the gas tank, meaning they are insensitive to pollution.
A carriage is used to extract and introduce the fuses in the
fuse carriers, thus simplifying operation and ensuring the
correct positioning of the fuse.
The pipe seal consists of an elastic membrane with the
following functions:
• To maintain the sealtight integrity of the fuse carriers
from ooding, and therefore avoid pollution and interior
degradation.
• Additional isolation provided by the isolation of the fuse
holder carriage itself.
• To transmit the movement of the fuse striker to the
switch tripping mechanism, while maintaining the
sealing of the fuse carrier.
By the very nature of its construction, this sealed solution
is subject to the internal overpressure caused by abnormal
overheating of the interior air. The trigger device can, in
this case, act as protection against overheating, preventing
damage both to the fuse and to the fuse carrier.
Figure 1.7. Fuses compartment detail
Exterior cable connections (bushing)
cpg.0 cubicles have bushing on the front for medium-
voltage cable connection. These are made of epoxy resin
and can, thanks to their conguration, withstand the
current transformers. They are duly screened and designed
in line with Standard EN 50181, type "C".
They allow conductors to be connected via screwable
T-type connectors of any manufacturer.
The cable clamps in the cable compartment hold the
cables at their input to the cubicle and prevent the
connector and bushing combination from supporting
the weight of the cable.
If cable input/output is via a trench over 2 m deep,
the cables must be fastened with additional cable
clamps, depending on the depth of the trench and the
cable cross-section (weight), in order to prevent the
connector and bushing combination from supporting
the weight of the cable.

Handling and transport General instructions
cpg.0: GIS medium-voltage switchgear,
gas insulated, up to 40.5 kV,
in accordance with IEC Standard
4. Handling and transport
4.1. Transport conditions
During transport, the switchgear must be perfectly seated
and xed so that it cannot move about and possibly
damage the equipment. Always in upright position, directly
on the ground or on a timber pallet, depending on the
type of handling to be carried out. Check that the cubicle is
perfectly balanced at all times.
4.2. Lifting means
cpg.0 cubicles can be handled either by lifting (with slings)
or using a forklift truck (with pallet):

Storage General instructions
cpg.0: GIS medium-voltage switchgear,
gas insulated, up to 40.5 kV,
in accordance with IEC Standard
5. Storage
If it needs to be stored, the material must be placed on dry
ground or damp-proof insulating material, still in its original
packing, in order to prevent any damage during storage.
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 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°C. There are also cubicles with storage temperature
up to -15°C and up to -25ºC.
3. The switchgear must be protected from direct solar
radiation.
4. Maximum altitude is 1000 m.
5. The environmental air must not have any signicant
contamination from dust, smoke, corrosive and/or
inammable gases, vapours or salt.
6. The switchgear must be protected from the rain, and
the humidity conditions must be as follows:
a. The average relative humidity value, measured over
a period of 24 hours, must not exceed 95 %.
b. The average water vapour pressure value, measured
over a period of 24 hours, must not exceed 2.2 kPa.
c. The average relative humidity value, measured over
a period of one month, must not exceed 90 %.
d. The mean water vapour pressure value, measured
over a period of one month, must not exceed
1.8 kPa.
7. During transport, vibrations caused by external factors
or seismic movements must be insignicant.
Any other conditions must be notied beforehand, since
the equipment must be factory-adjusted to atmospheric
pressure at the destination. If this is not the case, the
manometer needle may indicate an incorrect value, even if
the equipment's internal pressure is correct.
