Resimold
Main characteristics
• Single and three-phase units
• Ratings up to 5 MVA, 36.2 kV
• Frequency: 50/60 Hz
• AN cooling for continuous indoor service
(with AF and outdoor options)
• Normal or reduced losses
Cost savings and safety are our priorities
Encapsulated in epoxy resin under vacuum,
Resimold dry type transformers ensure high performance, safety and cost savings. With no risk of
explosion or release of toxic fumes, they comply
with rigorous international safety standards.
The metallic enclosures developed by Schneider Electric offer various levels of protection and
provide maximum operator and equipment safety.
This permits installation next to the load center,
thus providing power-savings and reduced low
voltage cable requirements.
In addition, insurance costs are reduced. They
don’t require special storage construction and are
maintenance-free. Their design is well adapted
for shopping malls, office buildings, hospitals,
airports, industrial plants and auxiliary services in
power-supply plants.
Resimold dry type transformers are the right
choice when cost-savings and safety are required
in a single product.
Flame resistant and self-extinguishing,
Resimold provides an effective solution for
infrastructure projects and public buildings
confronted by fire hazards.

Resimold for a modern world
Minimizing space requirements and associated
civil works costs is a major issue in most building
projects today. Whether it is for a new city center
office block, an expansion in industrial process
capacity or a wind farm project, the compact
design of Resimold provides a cost-effective solution.

Resimold
HV winding
The exclusive casting system and advanced technology used in our HV windings give Resimold
transformers the reliability and operating characteristics needed in high-technology applications
which demand maximum availability of electricity
supply.
This HV winding technology results in a compact
single block.
Casting system
In the face of increasingly strict regulations with
regard to the risk of fire and pollution, Schneider
Electric practices a policy of permanent research
on the behavior of insulating materials in fires.
This has led to the exclusive Class F casting
system (temperature of insulation system: 155°C)
developed in our laboratories.
This system is comprised of three main components:
• Epoxy resin
• Hardener
• Mineral filler
When polymerized, the epoxy resins associated
with the hardener form a stable three-dimensional
network.
These systems have better properties than most
plastics. Their use in transformers is justified owing to their:
• Excellent resistance to thermal aging
• Remarkable adherence to almost all known
materials.
Exceptional performance renders the windings
resistant to many chemicals. Mechanical strength
and a high-thermal conductivity are achieved by
incorporating selected mineral fillers. This enables
heat to be evacuated during use, improving fire
resistance and dramatically reducing the quantity
of combustible materials.
After hardening by polymerization, the casting
system becomes permanent. It offers excellent
fire behavior and immediate self-extinction, well
beyond the rated conditions of use. Resimold
transformers can hence be qualified as truly
flame-resistant and self-extinguishing.
PM102240
The HV winding design is in disc format with a
choice of aluminum strips or insulated aluminum
wire (or copper for special projects) cast under
vacuum in molds.
The solid insulation is obtained by vacuum casting in pre-heated molds, followed by a hardening
period under controlled temperatures.

Resiglas - flexibility and sturdiness for
special requirements
With all the intrinsic features of encapsulated
epoxy resin dry transformers (flame-resistant, no
toxic fumes, no partial discharges as per standard
IEC 60076-11), Resiglas brings you even more.
Thanks to the epoxy resin encapsulated coils
reinforced with fiberglass, as well as immunity to
environmental conditions and its fire-resistant categories E1/F1/C1, Resiglas technology presents
considerable advantages over conventional dry
transformers:
• Higher mechanical sturdiness since the
encapsulating process consists of continuous
fiberglass filaments
• Higher resistance to short-circuits and earthquake strains
Higher resistance to transient over-voltages
Safe for long-distance shipments
The exclusive cooling ducts designed for this
technology provide for optimal performance
when forced ventilation is required
Design flexibility in order to meet system
requirements (dimensions, impedance, etc).

Resiglas
Resiglas adapted to special applications
Resiglas dry type transformers can be
designed to meet special requirements, such as:
• Power distribution on off-shore oil platforms
to supply heavy-duty machinery
• Generator static excitement (6-pulse rectifiers)
• Power supply to low and medium voltage
drives for frequency inverters (6, 12, 18, 24,
36 pulses)
• Installation in outdoor locations and in rooms
with aggressive conditions
• Power supply of non-linear loads with high
harmonic contents (transformers with kfactor)
• Grounding systems
• Set-up transformers for generating group
outputs
• Power supply for induction furnaces
• Electrical drive systems for railway lines
HV winding
The winding consists of round or rectangular copper or aluminum wires. It is wound continuously.
The coil is formed by blocks, typically from 2 to 3
blocks of insulating material and winding, which
allows cooling ducts to be formed in the mediumvoltage coil itself. These cooling ducts also allow
a separation of the superimposed winding.
Casting system
The Resiglas technology consists of the encapsulation of the medium-voltage coils with epoxy
resin and fiberglass without the need to use steel
molds. The winding occurs over an expandable
radius cylinder, which is adjusted according to
design needs. The epoxy resin has the function of
assuring the dielectric strength of the coil, while
the fiberglass, in continuous strings, provides
mechanical strength in the coils.
Medium voltage drives
Cost-savings, quality and system reliability
With the technological improvements in medium voltage starters for heavy-duty motors, the
Resiglas dry transformers are now equipped with
intelligent solutions. One example is dephasing
transformers, supplying drives with medium voltage.
Our dry transformers are capable of withstanding
those electrical and mechanical strains resulting
from harmonic currents and voltage transients
caused by the rectifying system - while maintaining excellent performance levels.
Our design flexibility allows for the adjustment of
impedances, obtaining proper angular dephasing and voltage relationships, thus optimizing
the drive operation with a minimum of harmonic
distortion in the power supply mains.
Resiglas can be used with rectifiers of 6,12,18,24
and 36 pulses, meaning that the dephasing
obtained for each of the rectifier types allows for a
significant reduction in the harmonics returning to
the mains.
All Schneider Electric transformers, when requested, can be specially designed for non-linear loads
in order to minimize losses caused by harmonic
currents and generate less heat to be dissipated.
Examples of k-factor applicable to a few types of
loads:
• Excitement of power generators: k = 6 or
k=8
• Frequency rectifiers / converters: k = 8
• No breaks: k = 13 or k = 20
