ABB VACUUM CAST COIL TRANSFORMER
CERTIFICATIONS & CLASSES
ABB vacuum cast coil transformers range from 50 KVA up to 30
MVA with operating voltages up to 52 kV.
The use of cast resin, combined with our latest manufacturing
techniques allows us to build stronger compact transformers
capable of withstanding severe rolling and vibration.
Vacuum cast coil transformers are virtually maintenance free.
They do not require any special civil works prior to installation and
due to the particular design they can be repaired on site.
ABB vacuum cast coil transformers are manufactured in
accordance with the international quality standards ISO 9001 and
ISO 14001.

The magnetic core has a miltered step-lap joint to ensure
optimum performance and minimum sound levels. The magnetic
steel is cut to length in a sequential way and automatically
stacked, ensuring dimensional accuracy and single sheet
interlacing within the full stack.
ENCLOSURE IP 21
The high voltage winding has a continuous drop down disc with
a strip conductor and double layer insulation. Transient analysis
tests have been performed to verify the electrical stress
distribution through the windings confirming the highest strength
in our design.
The encapsulation process is a fundamental operation in the
manufacturing procedure and should be carried out and controlled
under the most strict conditions in order to ensure optimal
insulating and mechanical characteristics. The windings, are put
through a preheating oven and kept inside until the mould
temperature reaches the encapsulation temperature. The resin
mix on the other hand, is prepared in a continuous mixing plant.
Components are mixed together just before the encapsulation
process. In the next step, the preheated coils are moved into the
vacuum casting chamber. Once the vacuum in the chamber has
been reached, the resin is poured into the moulds. In this way the
viscosity of the resin mix when poured in the mould is very low,
filing interstices allowing to reach the lowest level of partial
discharges. After the casting is finished the coils are placed into
the curing oven for the resin compound gel to cure and to achieve
its final properties.
The low voltage windings are made of insulating foil
preimpregnated with resin. After the winding process the coil is
cured into an oven resulting in an extremely compact winding
which can withstand the dynamic stresses produced by a shortcircuit.
