Efficiency
Single-phase
encapsulated
(dry-type)
transformers
use
solid
insulation
to
provide
electrical
insulation
and
cooling,
eliminating
oil
or
liquid-filled
insulation.
Commonly
used
indoors
for
improved
fire
safety,
environmental
compatibility,
and
easier
installation,
"encapsulated"
means
the
windings
and
core
are
embedded
in
solid
potting
material.
Enclosure:
constructed
from
high-quality
304
stainless
steel
for
superior
corrosion
resistance,
mechanical
strength,
and
lasting
appearance,
the
housing
protects
internal
components
from
moisture,
chemicals,
and
environmental
contaminants
common
in
industrial
and
outdoor
sites.
Built
to
NEMA
4X
standards,
the
watertight,
corrosion-resistant
enclosure
is
suitable
for
outdoor
and
washdown
environments
and
resists
windblown
dust
and
rain,
splashing
and
hose-directed
water--making
it
ideal
for
coastal,
chemical-processing,
and
other
harsh
conditions.

Key
Benefits
-
Dry-type
insulation:
They
use
solid
insulation
instead
of
oil,
eliminating
the
risk
of
oil
leaks
and
associated
environmental
hazards.
-
Improved
fire
safety:
With
no
flammable
liquid
present,
they
are
safer
for
indoor
installations
and
better
meet
strict
fire-safety
codes.
-
Environmentally
friendly:
The
absence
of
oil
reduces
the
potential
for
soil
or
water
contamination.
-
Low
maintenance:
They
avoid
oil-related
upkeep
such
as
sampling
and
testing,
lowering
routine
maintenance
needs.
-
Flexible
installation:
They
can
be
sited
indoors
without
special
vaults
or
containment
systems
since
there's
no
oil
spill
risk.
-
Lower
cooling
demands:
The
encapsulation
material
provides
insulation
and
thermal
management,
so
cooling
requirements
are
generally
less
than
for
oil-filled
units.
Applications
Single-phase
encapsulated
transformers
are
commonly
used
in
various
applications,
including
commercial
buildings,
industrial
facilities,
hospitals,
schools,
data
centers,
and
more.
