Increasing environmental awareness and
demand for electric energy coupled with modern
urbanization trends have led ABB to develop
innovative products for the supply, generation
and transmission of power. Transformers are
critical components in energy grid systems and are
increasingly required to operate at reduced risk to
humans and eco-sensitive environments.
Transformers, which traditionally use mineral
oil for insulation and cooling, allow energy to be
transported from the production source to the
location where power is needed. Increasingly
located in metropolitan areas →1 and near
environmentally sensitive areas like harbors,
transformers that use oil can pose safety and
environmental challenges and generate additional
long term costs. Since the late 1980’s ABB has
sought alternative liquids and materials to reduce
these risks. Oil-free transformers have continued to
be a viable alternative in a growing number of niche
markets, where ecology and safety drive choice.
Advantages of oil-filled transformers
Currently, oil-filled and oil-free (dry-type)
transformers are available; the obvious difference is
the presence or absence of oil. Oil has ideal dielectric
and cooling properties for use in transformers.
Oil-free transformers rely solely on solid insulation
ie, polyester films, aramid fibers and epoxies as the
dielectric material and ambient air for cooling.
Though the dielectric capabilities of solid
insulations are comparable to that of oil [2],
transformer oils are orders of magnitude better
at cooling than ambient air. This allows oil-filled
transformers to be smaller, lighter, and produce
lower noise levels than dry-type transformers of
equivalent power ratings. These advantages have
made oil-filled transformers the primary technology
for today’s globally installed transformer market
