Air-insulated medium-voltage switchgear –
cleverly switched, local added value
Peace of mind, saves lives,
increases productivity, saves money
Answers for energy.
Experience and quality for maximum
system safety
The industrialized world of today is characterized by a rising
energy demand and growing environmental consciousness concurrently with an increasing price pressure. At the same time,
users are of course placing maximum demands regarding reliability, personal protection and productivity in connection with
switchgear operation.
There is one thing you just have to rely on: smooth and safe
operation of your system. Around the clock. Here, switchgear
assemblies as points of intersection play a decisive role – and
air-insulated switchgear concepts from our worldwide production locations offer the best solution with no doubt.
As a pioneer for air-insulated switchgear we bring along 25 years
of know-how in the development of switchgear and switching
devices. Along with this, our manufacturing plants in all regions
of the world ensure local added value and thus, permanent proximity to the customer, so that you can take full advantage of airinsulated technology: As insulating medium, air is available day
and night, and withdrawable switchgear systems guarantee
accessibility to all switchgear components at any time.
With air-insulated switchgear from Siemens you are always on
the safe side – our switchgear is type-tested for indoor installation according to IEC 62271-200 or ANSI/IEEE C37.20.2. In this
way you profit from our leading position as regards fulfillment of
this new standard IEC 62271-200. Regardless of the fact that airinsulated switchgear from Siemens has always been a synonym
for maximum personal and opera-tional safety as well as local
added value.
Keep everything going in your power supply system:
Air-insulated switchgear from Siemens –
for sustainability, safety and efficiency
Peace of mind
With its sophisticated technology, a globally interconnected
R&D network, a worldwide production and quality network and
the fulfillment of all type and routine tests according to the requirements of the international standards without restrictions,
air-insulated switchgear offers maximum peace of mind.
Saves lives
All air-insulated switchgear designs from Siemens are approved
with internal arc classification IAC A FLR, loss of service continuity
category LSC 2B, LSC 2A or LSC 1 depending on the switchgear
type, as well as partition class PM. Thus they can be universally
installed, fulfilling maximum requirements as regards personal
protection.
Increases productivity
Functions such as evidence of the making and breaking capacity for the built-in circuit-breakers and earthing switches – and
even confinement of the arc to the respective compartment depending on the switchgear type – as well as designs equipped
to meet maximum requirements with respect to the degree of
protection provide uninterrupted operation and an appreciable
increase of productivity.
Saves money
The compact design and the use of vacuum circuit-breakers pay
off twice for the switchgear operator. On the one hand, building costs can be reduced, and on the other hand, the maintenance-free design of the circuit-breakers enables continuous
operation without expensive downtimes.
Siemens – your partner on site
We take care that you can “switch cleverly“. Combining innovation, experience and local added value. With comprehensive
know-how, worldwide service – and profound understanding
of your requirements in the most different regions due to local
production capacity. Go and see for yourself!
Local added value – systematically:
Worldwide production –
complete processes –
a quality standard
R&D headquarters in Germany
concentrate international know-how
All global development activities are concentrated and controlled
centrally: International development teams introduce the respective country-specific requirements in our R&D activities.
A good basis for maximum development synergies, contributing
to lean development cycles by means of optimal exchange of
experience.
High demands – in practical implementation:
The 3D-CAD procedure
During the development and production phase, the utilization of
3D-CAD software ensures perfect quality and reliability. The individual technical data of your switchgear is transferred directly
from the purchase order to the production department via the
design department. Using innovative technologies we can offer
a maximum of quality and flexibility in production – with short
delivery times.
Local added value – country-specific flexibility
Hundreds of Siemens employees manufacture our air-insulated
switchgear type series in different regions worldwide. In this
way we do not only ensure the local know-how for the requirements varying from country to country, but also integrate experience from other locations. Production processes are documented in a comprehensible way – to reach the quality level
you, as our customer, can expect in a fast, safe and reproducible way.
Strict eyes – to assure the quality
Our very modern, accredited testing laboratories ensure the
high quality of our air-insulated switchgear. Besides type and
routine tests for the individual switchgear type series, continuous process-accompanying quality assurance according to
ISO 9001 and 14001 is performed. Being associated with
PEHLA and DAR, our testing laboratories have the status of
independent test institutes.
