When researching the advantages of cast resin dry-type transformers, you may find the information available to be somewhat
incomplete. More so, only a few of its favourable features are well known, with
one of the most noteworthy being its minimal fire risk due to zero oil usage.
Self-extinguishing, low fire
hazard:
The transformer insulation consists of an epoxy resin and quartz powder mixture (an eco-friendly material). This allows the winding to be flame-retardant, self extinguishing and almost maintenance free, eliminating the need for costly fire extinguishing equipment. It will also not produce toxic gases, not even under the effects of arcing.
Zero oil usage:
The cast resin transformer only
needs air to cool. Therefore, it eliminates extra costs and labour for
liquid-level checking, oil testing, oil recycling costs, and dielectric testing
for moisture absorption. Being almost maintenance free, there are no more
on-site oil leaks, which require gasket replacements.
Eco-friendly and safe:
Cast resin transformers pose
ZERO risk for oil leaks and pollution of the environment. Transformer
explosions during normal operation are highly unlikely due to the
self extinguishable non-toxic substances utilised, even during external fires.
They are also suitable for heavy condensation and polluted environments. Cast
resin transformers may also withstand abrupt environmental changes from -25ºC
to +40ºC in a very short time. TIP: Always try to ensure that your preferred manufacturer
has passed/ obtained C2/E2/F1 tests according to IEC 60076-11 and that it is
approved, i.e. KEMA type tested.
Low cost installation and lower
load losses:
There are almost no
restrictions on the installation site. Furthermore, there will be no groundwater
protection costs during site preparation. The closer the transformer is to the
load, the lower the cable losses and cost. Reliability: Cast resin transformers
have a service life expectancy of 20+ years, and a low failure rate when
operated within its designed parameters. This makes it a highly reliable
component of any electrical infrastructure. For proven reliability statistics
and case studies, please contact Arm Coil for further information.
Low maintenance:
Cast resin transformers only
need air to cool, and liquid testing becomes obsolete. Its smooth coil surface
eliminates heavy dirt build-up, even in the most extreme circumstances. The
only recommended maintenance is a routine visual inspection by technical
personnel, and a wipe down of the transformer as required.
High short time overload
capacity:
As the windings of cast resin
transformers are encapsulated in resin, the effects of axial and radial forces
under high current loads are eliminated. Therefore, cast resin transformers are
able to handle short time overloads far better than oil cooled units.
Crack-resistant:
Due to historical cracking of
cast resin transformers, the latest technology has introduced glass fibre
reinforcement in the windings that eliminates cracking due to its heating and
cooling curves.
Moisture-resistant:
The complete embedding of the
transformer winding in resin prevents the penetration of moisture. This results
in low maintenance and an extended transformer life.
Low noise levels
Due to design flux densities
and flexible winding supports, the noise levels during operation are reduced by
a considerable amount.
Compact design:
By the nature of the design,
cast resin transformers are more compact and require less space than oil cooled
units.
Sustainable:
Using cast resin transformers
contributes to saving our resources. Its design and operation is considerate of
the environment through: • A long service life of 20+ years, • Its low loss
levels; meaning it uses less electricity, and • 90% recyclable transformer
materials; meaning less waste. It should be noted that the choice between a
cast resin and oil-cooled transformer is always application dependent. However,
before making a decision, all requirements of the environment and operating
conditions need to be taken into consideration. Today, we live in a world where
initial cost is no longer the most important factor, with long-term costs on
the environment deserving serious contemplation. Considering the advantages of
cast resin dry-type transformers, and the increasing rate of natural resource
extraction – which would you say is the better choice?
