Benefits of an EdM transformer
The EdM high-quality cast resin transformer is the ideal
choice for all needs.
Using technical, state-of-the-art solutions and materials
of the highest quality, EdM cast resin transformers can
give you many advantages: total safety for the customer,
guaranteed by the total absence of combustible products;
maximum environmental protection, thanks to the absence
of polluting and inflammable insulating liquids;
energy saving, with the exclusive “reduced loss” range.
Unlike the oil solution, a cast resin transformer does not
require additional building structures, thus guaranteeing
the maximum practicality and flexibility straight from the
beginning of the installation.
Furthermore, no cooling fluids are used, hence minimizing
maintenance costs.
REDUCTION OF THE ENVIRONMENTAL IMPACT
– low fire hazard
– no risk of insulating fluid losses into the
environment
– possibility of retrieving end-of-life materials
– availability of a “reduced loss” range (energy
saving)
INSTALLATION SIMPLIFICATION
– reduction of the overall dimensions
– reduction of expensive construction
achievements, i.e. oil recovery sump, (required
according to DpR 547/55 for oil transformers
with power equal to or higher than 630 KVA),
absence of fire-resistant separation barriers (not
required for class F1 cast resin transformers)
– possibility of installation inside buildings,
including places attended by people
– immediate integration with Zucchini busbars
FLEXIBILITY DURING USAGE
– it is possible to increase the delivered power
through the application of special ventilation
systems, to be used when dealing with
particular operating situations (temporary
overloads or high environmental temperatures)
or when it is necessary to have a temporary
reserve capacity in case of emergency
(nonfunctional transformer)
– no maintenance is required besides the
standard periodic checks.
ENERGY SAVING
By using EdM “reduced loss” cast
resin transformers, end-users
will not only be able to reduce
management costs, typical of
cast resin transformers, but also
save money on energy costs,
thus protecting the environment
and taking action against energy
waste.
EdM has developed a simple
mathematical model (available on
the website) which - depending on
the transformer selected, energy
usage profile of the customer and
on the energy costs - will produce
a curve of costs whereby it is
possible to point out the attainable
cost and energy saving.
For instance, comparing a 1000
kVA (cl. 24kV) “reduced loss”
transformer with a “distribution”
transformer, after 20 years of
operation the energy saving will
be 12000 KWh (less environmental
impact) and the cost effectiveness
for the customer will be about
28000€*.
For more details, see section
Energy Saving on our website.
* the calculation was based on 3% of the cost of
money and considering an energy cost of 0.19 €/kWh.
