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
requirements of standard EN 50110-1 on the safety of electrical installations and standard EN 50110-2 on activities in or near
electrical installations. Personnel must be fully familiar with the instructions and warnings contained in this manual and in other
recommendations of a more general nature which are applicable to the situation according to current legislation[1].
The above must be carefully observed, as the correct and safe operation of this equipment depends not only on its design but also
on general circumstances which are in general beyond the control and responsibility of the manufacturer. More specifically:
• The equipment must be handled and transported appropriately from the factory to the place of installation.
• All intermediate storage should occur in conditions which do not alter or damage the characteristics of the equipment
or its essential components.
• Service conditions must be compatible with the equipment rating.
• The equipment must be operated strictly in accordance with the instructions given in the manual, and the applicable
operating and safety principles must be clearly understood.
• Maintenance should be performed properly, taking into account the actual service and environmental conditions in
the place of installation.

Description and main characteristics
Each tank has a manometer for checking the gas
pressure, which can easily be seen from outside the
cubicle. The manometer scale is divided into dierent
colors: red, grey and green. For safe operation, the
needle must be in the green zone of the corresponding
temperature band.
Pressure gauge is not intended to be used for telemetry
purposes.

Description and main characteristics
General instructions
cgm.3 system: medium voltage SF6gas-insulated
cubicles up to 38 kV according to IEEE and CSA standards
Switch-disconnector and grounding switch: This has
three positions: closed, open or grounded.
This switch is operated using driving mechanisms with two
dierent shafts: one for the switch (switching between the
closed and open positions); and the other for the grounding
switch (which switches between the open and grounded
positions) on the feeder cables, and in the case of fused
protection cubicles, on the six fuse holder clamps.
These elements are operated independently so that their
actuation speed does not depend on the speed of the
manual operation.
Vacuum circuit-breaker: The cgm.3-v cubicle’s circuit-
breaker uses vacuum switching technology.
The circuit-breaker is actuated by means of the push-
button on the front of the cubicle. For manual operation,
springs must be charged with the corresponding lever.
To ensure that the isolating distance is adequate, the
cgm.3-v cubicle’s circuit-breaker comes standard with a
switch-disconnector and a grounding switch. This element
is operated using a specic lever.
The cgm.3-v circuit-breaker cubicles can be equipped with
an electromechanical safety device called an undervoltage
coil. Its function is to ensure that the cubicle switch opens
in the event of an unexpected drop of more than 30% in the
auxiliary voltage.
2. Driving mechanism compartment: this is the
compartment in which the switch-disconnector,
grounding switch or the circuit-breaker is actuated,
depending on the type of cubicle. The mimic diagram
for the main medium voltage circuit is displayed on the
cover of this compartment.
The mimic diagram includes all the position indicators
for the actuators.

3. Base: made up of the cable compartment (3a) and the
gas relief compartment (3b), see Figures 1.1 and 1.2.
The rst is located in the lower front part of the cubicle
and has a cover interlocked with the unit’s ground
connection, which allows front access to the medium
voltage cables.
The gas relief compartment is located in the lower rear
section of the cubicle. In the event of an internal arc,
the gases produced are deected downwards and to
the rear, and in no way aecting any persons, cables, or
the rest of the installation switchgear.
For cubicles with 1 s internal arc, the gases are diverted
to the trench.
Figure 1.16. Cable compartment
1.1.1. Voltage presence indication unit
Ormazabal has two voltage presence indication options:
• The ekor.vpis unit for detecting voltage, designed in
accordance with standard IEC 62271-206.
• The ekor.ivds unit for detecting voltage, designed in
accordance with standard IEC 61243-5.
Both units provide a clear visual indication for the user,
without needing an auxiliary power supply for its operation.
For each of the three phases, the presence of voltage is
indicated by intermittent ashing of the indicators.
The test points for the ground and the three phases make
it easier to check the phase balance between cubicles. Any
universal comparator which complies with specications of
standard IEC 62271-206 can be used for this purpose.
If the indicators do not light up, use other means to
check that there is no voltage. 1
The numbering corresponds to the order of the phases, from
left to right, seen from the front of the cubicle. Each phase has a
test point for checking the phase balance between cubicles.

3Voltage presence indicator
A ashing light indicates the presence of voltage in that phase.

1.1.2. ekor.sas - acoustic grounding prevention alarm unit
The ekor.sas grounding prevention alarm is an acoustic
indicator which works in association with the grounding
shaft handle and the ekor.vpis voltage presence indicator.
Both operate within the same range. The alarm is activated
when there is voltage in the cubicle’s medium voltage
feeder and the lever is inserted in the grounding switch
shaft. A sound then warns the operator that if he performs
the operation, a short-circuit in the network might occur.
This unit is standard on cgm.3 system feeder functional
units and supplied to order in the rest of the functional
units.

2.1. Lifting methods
The cubicles must always be kept upright, directly on the
ground or on a pallet depending on the type of handling
involved.
To handle cgm.3 assemblies with up to 4 functional units,
one of the following methods should be used:
1. Using a forklift truck or hand-operated pallet truck.
Position the rear of the cubicle facing the driver, to
avoid damaging the front.
Figure 2.1. Lifting a cgm.3 modular cubicle using a fork- lift truck
2. Raising it using slings xed to the lifting supports on
the sides of the top of the cubicle. The angle of pull
should be as vertical as possible (with an angle of more
than 60° from the horizontal).
Figure 2.2. Lifting a cgm.3 modular cubicle with slings
3. if it is not possible to use the aforementioned methods,
rollers may be used underneath the cubicles. Another
option is to slide the cubicles over rods (these same
rods can be used to get over the trench).

4. To handle 5 functional unit cgm.3 assemblies use lifting
systems (slings, lifting beam, etc.) with a pull angle
greater than 65° and less than 115° in order to prevent
possible damage to the cubicles during hoisting.
The use of lifting beams is required for cubicle
assemblies with control boxes As the sole exception,
slings may be used if the cubicles of the assembly have
identical height control boxes installed.

2.2. Location of documentation and accessories during transport
During transport, the cubicle must be perfectly seated and
xed so that it cannot move about and possibly damage the
equipment.
The corresponding documentation (General Instructions,
electrical diagrams, etc.) is supplied with the cubicles, as
well as a set of accessories located at the rear of the cubicles,
as indicated in the gures below:
The cubicle models with internal arc for 1 s have the
accessories box located on the roof of the tank.
