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 legislation1.
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.
The manufacturer declines all liability for any significant indirect damages resulting from violation of the guarantee, under any jurisdiction,
including loss of income, stoppages and costs resulting from repair or replacement of parts.
Warranty
The manufacturer guarantees this product against any defect in materials and operation during the contractual period. In the event that
defects are detected, the manufacturer may opt either to repair or replace the equipment. Improper handling of this equipment and its
repair by the user shall constitute a violation of the warranty.

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.

1.3 Main components
Each cubicle is made up of a series of independent
compartments:
Figure 1.1 Main elements of cpg.1 cubicles
Gas tanks
These are the compartments which house the switching
and breaking switchgear, where the insulating medium is
SF6gas. There are 2 or 3 separate compartments:
• 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.

Fully SF6 gas insulated single and double busbar GIS switchgears up to 36 kV in accordance
with IEC Standards
IG-137-EN version 03; 23/06/2016
For testing the gas pressure in each compartment, a
temperature-compensated pressure switch is installed,
with a volt-free contact, for possible use as a remote alarm
or blocking/trip for the functional unit.
Top busbar
This is used for connecting cubicles. It has solid and
shielded insulation, earthed by means of the compartment's
specific earthing bar.
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.
Cable compartment
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.
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.
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.

Gas pressure relief duct (optional)
Figure 1.4 Internal arc gas pressure relief duct (optional)
This component is used to direct the gases produced by
an internal arc in any of the compartments towards the
top of the cubicle: Disconnector compartment and circuit
breaker compartment, top busbar compartment and cable
compartment.
Control compartment
Placed at the top of the cubicle and separate from the
medium voltage area, this is ready for installation of the
metering equipment and protection relays. It contains
the whole terminal block with the control signals already
identified.

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, directly
on the ground or on a pallet, depending on the type of
handling involved. Check that the switchgear is perfectly
balanced at all times.
4.2 Lifting means
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.
Figure 4.1 Lifting a cpg.1 cubicle using slings
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.
