Gas-insulated
medium-voltage switchgear
from Siemens
The right solution
The world-wide need for power will
continue to increase over the coming
years due to the constant population
growth, ongoing urbanization, and new
trends such as electro-mobility, for
example. This represents a complex
challenge for medium-voltage systems:
Due to the increasing number of
growing urban areas and increasing
real estate prices, switchgear is having
to become increasingly more compact.
In order to achieve climate targets,
medium-voltage systems must be able to
accommodate increasingly more power
in the form of renewable energy.
Intelligent switchgear which is required
to be both environmentally friendly and
sustainable from the point of manufacture
through operation up to the point of
disposal is in demand in increasing
numbers. In addition to the high level
of personal safety required, economical
aspects and the reliability of the
switchgear are particularly important.
Gas-insulated medium-voltage switchgear
from Siemens is the right solution for all of
these requirements.

Impressive for energy suppliers
Economical and safe: Gas-insulated
medium-voltage switchgear from Siemens
are impressing power supply companies
(EVUs) world-wide due to their extensive
personal and operational safety and their
cost-efficient, maintenance-free, and
trouble-free operation. In addition, power
supply companies are benefiting from
the compact design of gas-insulated
switchgear from Siemens, which facilitate
the setup of compact transformer
substations or their refitting or retrofitting.
Reliable both offshore and onshore
Wind parks also have specific requirements, not only with respect to the place
of use. Our gas-insulated medium-voltage
switchgear, with its climate-independent
maintenance-free technology and minimal
space requirements, enable safe connection of the wind parks to the power grid
and make a sustainable contribution to
environmental protection.
Trouble-free in the mining industry
If you need maximum availability and
reliability under extreme conditions, such
as in lignite open-cast mining, then gasinsulated medium-voltage switchgear from
Siemens is the first choice. It functions
trouble-free around-the-clock in an atmosphere of electrically conducting coal dust
under the most varied of ambient temperatures and under high mechanical stresses.
High-performance in the metal industry
The performance demands in metal industry companies are enormous: Connection
loads of up to 300 MW – this corresponds
to a power consumption of more than
300,000 households – are common. Our
gas-insulated medium-voltage switchgear
can support the safe flow of all processes
by reliably switching and distributing large
quantities of power.
The hardest conditions in the oil and
gas industry
Exploration and conveyor systems in the
oil and gas industry must have a troublefree, safe power supply and require maximum power in the tightest of spaces. Gasinsulated medium-voltage switchgear from
Siemens reliably performs its tasks even
under extreme conditions. Therefore, they
are particularly well-suited for oil and gas
applications because operational safety
and availability are absolutely necessary.
For almost any
application
■■
Gas-insulated mediumvoltage switchgear from
Siemens also ensures
optimum current flow in
other applications such
as computing centers or
branches such as the auto­
motive industry, chemical
industry, and the food
and beverage industry.
Safety and compactness for modern
infrastructure
Modern infrastructure such as airports and
office buildings are placing increasingly
higher demands on safety, flexibility, and
less environmental pollution over the
entire service life. Our compact, gas-insulated medium-voltage switchgear in this
case helps to support the establishment
of safe medium-voltage power distribution
and reliably provide power to large
consumers and the low-voltage system.
5
Impressive advantages
Future-proof investment
In these times of growing cost and
performance pressure, it is even more
important to decide on the right
technology, especially when switchgear
represents an investment for decades.
Compactness, performance capability,
climate independence, and cost-efficiency
in this case supplement the central aspects
of gas-insulated medium-voltage switchgear from Siemens making it a sound
investment for the future; it also provides
optimum personal and functional safety
and reliable, maintenance-free operation.
6
In addition, our service contributes to
power distribution: Within the scope of
Totally Integrated Power, we offer you
much more than products, systems, and
solutions for power distribution. We will
support you through the entire process
and life-cycle of switchgear – starting from
the initial idea to completion and aftersales service. We offer tools for planning of
switchgear and system architecture, help
with energy management and monitoring,
and we offer training and education in the
perfect use of our product line.
Compact
A gas-insulated medium-voltage switchgear also assures you many advantages
in the future due to the technically
superior solutions including protection of
your investments from the target-oriented
switchgear extension. Thanks to its
compact construction, it offers you space
savings of up to 70 % with the 36 kV
switchgear for primary distribution –
and provides the space for new functions
or the compact design of transformer
substations.
Maintenance-free
A cost-efficient operation is one of the
key factors for system operators. This also
includes particularly long maintenance
intervals.
Hermetically-sealed, welded switchgear
vessels made of stainless steel (sealed pressure system) ensure tightness for the entire
service life as per IEC 62271-200, which
means that maintenance of function is
normally determined by the service life of
the switchgear inside. This is determined,
for example, for vacuum circuit-breakers
under normal ambient conditions as per
IEC 62271-1 with up to 10,000 operating
cycles without relubrication or
readjustment.
Our switchgear is therefore practically
maintenance-free – which ensures
maximum availability with extensive
cost-efficiency.
Climate-independent
Even under the most extreme ambient
conditions, such as salty air, high air
humidity, conductive dust or condensation, our gas-insulated switchgear has
proven to be the ideal solution and,
depending on the switchgear design, will
fulfill your needs regardless of air pressure
or altitude. They are reliable, owing to
the superior technology – which ensures
the safety of your distribution system.
Intelligent
With respect to integration into the
upstream control and energy management
systems: There are a variety of communication and telecontrol units available for
implementing an interface via various
protocols (e.g. IEC 61850, IEC 60870-5101/104, PROFIBUS, MODBUS, DNP).
In the age of intelligent grids, so-called
Smart Grids, stations must be able to integrate smoothly into the new grid control
structures. To do this, medium-voltage
switchgear should be equipped, amongst
other things, with motor drives and
compact telecontrol units. Depending on
the configuration, errors can be localized
more quickly, and measured values can be
gathered and transferred. In addition, load
curves can be recorded, overloads can
be detected early on, decentralized supply
can be controlled, and losses in the
distribution system can be minimized.
7
Personal safety
Gas-insulated medium-voltage switchgear
from Siemens is very safe. They meet
international safety requirements and are
internal arc classified in accordance with
IEC 62271-200. This high level of safety is
achieved, among other things, by design
measures such as the hermetically sealed,
shock-proof primary enclosure and the
metal enclosure of all high-voltage conducting parts, including cable terminations, busbars, and voltage transformers,
as well as earthed sheathing.
In addition to standard protection class
IP 65 for all high-voltage parts, the primary
circuit ensures advanced control logic to
provide additional safety. Logical mechanical interlocks prevent maloperation.
In addition, safe isolation from supply can
be verified with a capacitive voltage
detecting system. All operating mechanisms and auxiliary switches are accessible
outside the primary enclosure without
danger, while operation is possible,
depending on the system, only with the
switchgear enclosure closed.
8
Security of operation
Cost-efficient goals go hand-in-hand with
a high level of operational safety. Gas-insulated switchgear from Siemens will support you with a largely maintenance-free,
stable, and tested design – for maximum
availability even under extreme environmental conditions. Thus, the hermetically
sealed primary enclosure makes the
switchgear insensitive to environmental
influences but also to the penetration of
foreign objects or small animals.
No significant electrical fields occur outside the enclosure, which means that no
partial discharge can occur via pollution
layers in the long term. In addition, the
welded switchgear vessels are sealed for
life, and the electrical and thermal stresses
of the current transformers as well as the
low-voltage components are practically
zero.
Environmentally responsible
Our manufacturing plants are certified in
accordance with DIN EN ISO 14001 – we
place particular value on the preservation
of resources in all of our production
processes. This also means that we select
environmentally compatible materials,
even at the product development phase,
and minimize the material and energy
consumption through production-friendly
development. Thus, our gas-insulated
switchgear has a small "footprint" not only
because of the compact design but also
from an ecological perspective.
After its service life, lasting decades, is
over, we take on the responsibility of
recycling the switchgear in accordance
with the valid standards.
In addition, we check every switchgear
vessel with helium in the vacuum test cell
for leaks. Our goal for each individual
switchgear vessel is "Sealed for life".
Reliable
With long-lasting products such as our
gas-insulated medium-voltage switchgear,
absolute quality, precisely tailored to the
specific preconditions and requirements
of the place of use, is at the focal point of
our work.
We also do not compromise with crucial
components such as insulation parts made
of cast resin; instead, we produce them
ourselves and ensure their quality and
function 100 % by X-ray and tightness,
high-voltage, and partial discharge testing.
We achieve optimum adaptation to local
challenges through our internationally
constituted development teams and
customer-oriented manufacturing centers,
which are certified according to DIN EN
ISO 9001 and 14001. Crucial for highquality, however, is not only the management systems but also excellent training
and education of our employees and the
use of innovative technologies such as
highly precise laser welding systems that
we use to ensure that the vessels will have
high gas-tightness levels. The electric
bushings of the stainless steel vessels are
welded without seals – as are the mechanisms for transferring the operating energy
to the switching devices within the vessel.
Competent local support
Our experts provide support and advice
world-wide regarding the optimum solutions for your secondary distribution system. You will benefit, among other things,
from our specific know-how in project
management and our financing services
and also from the fact that our experienced customer service representatives
