Transformers for harsh environments
The Siemens transformer portfolio for the oil and gas industry
Siemens Transformers talks oil and gas
The oil and gas industry is one of the most
important and most vital sectors that
Siemens works with. Siemens offers a
wide range of products and services for
this critical backbone of today’s energy
supply. Longterm relationships between
Siemens and this industry have led to
numerous successful projects and references. But behind the obvious needs of
the industry – like drilling, compression,
and pumping products – it is transformers that keep the systems running.
The scope of applications is just as broad
as the range of locations where transformers are needed:
Special circumstances call for
special transformers
The oil and gas industry has to deal with
a variety of obstacles in diverse locations
every day. The transformer should not be
a component that demands attention,
and so Siemens takes this burden off of
its customers’ shoulders. We know that
the cost of ownership needs to be at the
lowest possible level when it comes to
transformers – whether it’s low losses
and efficiency, low maintenance and
service costs, or the potential risk of outages. We ensure our customers’ peace of
mind by building transformers that are
safe

In addition, all transformers for this industry need to adhere to the ATEX guideline
on explosion prevention and protection.

Transformers for every oil and gas application
Transformers for every environment
On- or offshore, in deserts, at sea, or sub-sea – the environments where oil and gas equipment is deployed are
both harsh and diverse. That’s why we build transformers
to withstand extremely high as well as very low temperatures. Whether it’s sand, wind, salt, or ice – the corrosion
protection and stainless steel used by Siemens E T TR will
reliably protect your transformers.
Siemens cast-resin transformers GEAFOL are entirely
oil-free. They can be used in very humid or dirty environments with no negative effects on their efficiency or
lifetime.
Fire safety and environmental care
While the global track record of our transformers is quite
impressive, we’d prefer that our products had no ecological impact whatsoever. Especially for fragile environments
like the sea or nature reserves, we design and build transformers that are explosion-safe and reduce fire risks.
The usage of alternative insulating fluids like MIDEL or
cast-resin transformers reduces those risks to a minimum.
All of our transformers for the oil and gas industries
follow the ATEX guidelines and adhere to all local norms
(IEC, ANSI/IEEE).
Transformer portfolio for oil and gas
Siemens offers a broad variety of transformers for the
oil and gas industry. Distribution transformers can be
manufactured as either liquid-immersed (with conservator
or hermetically sealed) or dry-type. Special transformers
for drives, pumps, and compressors complete our port­
folio. For particular customers and within frame agreements, it is also possible to design a custom transformer
for a specific application or environment.
For example, Siemens Transformers created a special
transformer for wind turbines where a robust coating
and extra-small dimensions were combined in a highly
efficient product.
