SecoGear 3.3kV-27kV Air Insulated Switchgear
Built to highest quality standards Circuit breaker making and breaking capacity
Earthing switch making capacity
Fully type tested to latest IEC standards
SecoGear is designed and fully third-
party type tested to the latest IEC 62271-
200 standards. It is fully isolated by
earthed metal partitions for all the major
compartments. It is equipped with GE' s
very latest series of IEC vacuum circuit
breakers type SecoVac, which are fully
third party type tested in accordance
with IEC 62771-100. Using GE’s state of
the art technology, and manufactured
in accordance with the highest quality
standards; our engineers have integrated
core technologies. These technologies
such as circuit breaker and mechanism
design, vacuum arc control technology,
insulation technology and electrical field
control and analysis combine to build
a highly reliable and compact system.
SecoGear benefits from GE' s best
practices incorporated in our current
medium voltage.
The typical rated voltage of SecoGear
is 3.3/7.2/12/13.8/15/17.5/24/27kV and
rated current ranges for SecoGear up to
17.5 is from 630A to 4000A(4000A is force
cooled), for SecoGear 24/27kV the rated
current is up to 2500A. All SecoGear with a
switching device is equipped with SecoVac
vacuum circuit breaker with corresponding
specifications.
The SecoVac vacuum circuit breaker is
subjected to the rated current and short-
circuit current breaking tests.
Furthermore, it is also subjected to the
opening and closing of capacitive and
inductive loads, capacitor banks and/or
cable lines.
The earth switch of the SecoGear
switchgear can be closed under short-
circuit up to 31.5kA. The earth switch
is interlocked to avoid being operated
on circuits which are still live. However,
should the switch be accidentally closed
then safety of the operating personnel is
assured by arc fault containment.
The switchgear is type tested to the
latest IEC 62271-200 and has the third
party certification to prove internal arc
containment classification of AFLR from
31.5kA for 1 second and up to 40kA for 1
second, 24/27kV 31.5kA/1s. This means
protection against harm to personnel in
the unlikely event of an internal arc in
the cable compartment, vacuum circuit
breaker compartment and the bus bar
compartment in any direction: front, rear
and sides of the switchgear.

Mechanical operations
IP degree
High ambient temperatures
Seismic rating
The mechanical endurance tests on all
the operating parts ensure the reliability
of the apparatus. General experience
in the electro-technical sector shows
that mechanical faults are one of the
most common causes of a fault in an
installation.
The circuit breaker is tested by carrying
out a high number of operations - higher
than those which are normally carried out
by installations in the field.
Furthermore, the switchgear components
are part of a quality control program
and samples are regularly taken from
the production lines and subjected to
total mechanical life tests to verify that
the quality is identical to that of the
components subjected to the type tests.
The IP protection degree is the resistance
offered by SecoGear against penetration
of solid objects and liquids. This degree
of resistance is indicated by the prefix IP
followed by two characters (IP 4X is for the
enclosure and IP 2X for the partitions.).
The first number identifies the degree of
protection against the entrance of solid
objects, the second one is related to
liquids.
The service conditions for the electrical
apparatus in marine installations are
generally more severe than those in
normal land applications. Temperatures
are a main factor and for this reason the
shipping register regulations require the
switchgear to be able to operate at higher
ambient temperatures (40 °C or higher).

Environment
Increasing global legislation concerning the use of green -
house gases such as SF6 gas and their related disposal costs,
makes vacuum technology with its reliability, low maintenance,
and low environmental impact the choice for now and the
future.
As the world strives to reduce the amount of SF6 gas used
in all applications there is a responsibility on the users of
electrical switchgear to find, where appropriate, alternatives to
SF6 gas as an insulation and switching medium. Air and solid
insulation switchgear systems incorporating vacuum switching
technologies are a reliable, safe and economic alternative for
use in electrical systems below 36kV and therefore should be
used instead of SF6 gas insulated systems.
Modern medium voltage switchgear employing vacuum
technology together with air and epoxy resin insulation
provides:
● Minimum number of parts and components
● No special requirements for the end-of-life disposal of the
switchgear
● Environmentally-friendly materials used in the design
● No use of SF6-gas for switching and insulation
● No risk of damaging leaks of SF6 gas or of toxic byproducts
● Energy-efficient production and assembly, with
environmentally friendly energy sources
● Minimal number of transition points in the primary design
enables low energy loss during operation
● Only re-usable and/or recyclable materials used
GE's production plants act entirely in
accordance with the rules and procedures
of the ISO 14001 environmental certificate
during development and production
processes.
Material selection and the number of
parts that are used to manufacture the
SecoGear are critical to determining
how environmentally friendly the
manufacturing process is. GE selects
its materials to ensure that they have
the lowest possible impact on the
environment. It is essential that they are
equally safe for people not just during use,
but at the end of service life too. Within
SecoGear and the SecoVac vacuum circuit
breaker, a combination of solid (cast-resin)
and air is used as insulation. The cast-
resin technology, in combination with
electrical field calculations, provides a very
compact, environmentally friendly design
for the circuit breaker and the switchgear.
Because the switching medium - vacuum
– is used, SecoGear can be completely
recycled at the end of its life without
any issues relating to safety procedures,
special handling or safe disposal.

SecoGear 3.3kV-27kV Air Insulated Switchgear
Envi
ronm
ent
Environmentally friendly
From the very beginning GE made a
fundamental choice not to use SF6 as
a switching and insulation medium for
primary medium voltage equipment. SF6
is on the list of greenhouse gasses in the
Kyoto protocol and is the most potent
of the six main greenhouse gasses, with
a Global Warming Potential (GWP) of
23,000. Many other medium voltage
switchgear systems use SF6 gas as the
insulating medium. Leakage of SF6 gas
from switchgear contributes significantly
to the threat of the greenhouse effect and
associated climate change. They also
require additional safety measures and
special handling requirements at the end
of life.
Minimum service checks on site
SecoGear is designed for a lifetime of at
least 20 years; therefore the energy usage
for maintenance activities during this
long period is minimal. Due to the green
insulation and switching technology,
there is also no leakage of the harmful
SF6 gas during its lifetime and no need for
performing extra maintenance activities
on SF6 gas pressure checks.
Minimal energy loss during operation
The number of electrical contact or
changeover points within the SecoGear
system has been kept to an absolute
minimum. This reduces the potential
number of "hot spots" and prevents
additional energy loss associated with
contact surfaces.
Energy efficient assembly
SecoGear is produced in an energy
efficient environment. Standard
processes and materials are used in the
design and require no special handling
or manufacturing processes, thus
reducing the amount of energy required
to manufacture and assemble the
switchgear.
Efficient use of materials
Besides the energy sources, special
focus is placed on the efficient use of
material during assembly. For example
by using advanced nesting tools the
hot dipped galvanized steel plates are
cut with the least amount of waste, and
similar principles are followed in the
design and manufacture of other product
components
Re-use or recycling of materials
All materials of SecoGear and SecoVac
can be reused, all materials are not any
impact on the environment, it fully reflects
the GE corporate social responsibility to
design and produce products.

Operating Conditions
Normal operating conditions
Special operating conditions
High altitude application
Note on any special climatic operating conditions
The switchgear is fundamentally designed
for the normal service conditions for
indoor switchgear to IEC Publication
62271-1. The following limit values, among
others, apply.
● Ambient temperature
- Maximum +40°C
- 24h-Medium +35°C
- Minimum -15°C
● Humidity
- Highest average value measured over
24 hours
- Relative humidity 95%
- Highest average value measured over
1 month
- Relative humidity 90%
● The maximum site altitude is 1000 m
above sea level
● Seismic Rating up to Uniform Building
Code (UBC) 1997 Zone 4
SecoGear is suitable for operation in the
climate of indoor type according to IEC
standard. Special operating conditions
must be discussed with GE in advance.
For example: At site altitudes above 1000
m, the effects of the reduction in density of
the air on the dielectric properties must be
taken into account.
Increased ambient temperatures must
be compensated for in the design of the
busbar and the branch conductors as well
as the withdrawable parts; otherwise the
current carrying capacity will be reduced.
Fitting additional ventilation facilities can
assist heat dissipation in the switchgear
panel.
The insulating capacity of the switchgear
with rated values of short-time power-
frequency withstand voltage and impulse
withstand voltage according to IEC62271-1.
When the switchgear is operated in areas
with high humidity and/or major rapid
temperature fluctuations, there is a risk
of condensation. Preventive action (e.g.
fitting the electric heater) must be taken
in consultation with the manufacturer to
avoid the condensation and any resulting
corrosion or other adverse effects. The
control of the heaters depends on the
relevant project.

Earthing Switch
The earthing switch can be operated from
the front of the switchgear. It is mechanically
interlocked with the circuit breaker truck so
that the earthing switch can only be operated
when the circuit breaker is open in the Test/
Disconnect position as well. The switch is
also mechanically interlocked with the cable
compartment for additional safety.

Cable Connection
The cable compartment contains current
transformers, voltage transformers (fixed),
withdrawable, and earthing switch,
depending on the individual operating
requirements.
The cable compartment is constructed for
installation of three current transformers.
When all the three current transformers
are not required, dummies can be installed
in their place to maintain the same
installation and connection procedures.
The fixed voltage transformers (optional)
are connected on the primary side
with busbar and fitted with HRC fuses.
The earthing switch can be operated
by manual, with position indicated by
mechanical indicator on the driveshaft
and the auxiliary switch. Three surge
arrestor (optional) can be mounted in the
space available.

Installation Guide
In order to obtain an optimum installation sequence and ensure
high quality standards, site installation of the switchgear should
only be carried out by specially trained personnel, or supervised
and monitored by qualified personnel, or by personnel supervised
and monitored by responsible persons.
On commencement of installation on site, the switch-room
must be fundamentally finished, provided with lighting and the
electricity supply, lockable, dry and with facilities for ventilation,
It is also required that the basic frame and indoor ground
of substation should be checked and accepted before the
construction, It must be ensure that the ceiling height is sufficient
for the opening travel of the pressure relief plates and clearance
for exhaust.
Tolerances for laying the floor frame are:
Evenness tolerance: ± 1mm within a measuring length of 1m,
Straightness tolerance: 1mm per 1m, but not more than 3mm
over entire length of frame.
