Both high- and low-voltage

cast in metal molds as separate
concentric cylinders.
High-voltage windings are wound using
foil strip technology. Multiple layers of

External molds are assembled and placed
in a vacuum chamber. Coils are preheated under high vacuum to remove
trapped moisture. A special mixture of
epoxy resin and quartz powder flows
into the mold through an opening in the
molding assembly. After pouring, the
molds are cured in a time-temperature
process controlled oven. The result is a

offering high magnetic permeability.
Core laminations are free of burrs and
stacked without gaps, resulting in the
lowest possible losses from magnetic
hysteresis and eddy currents. The core
clamping brackets are designed to provide
an even distribution of clamping forces
to the core yokes and legs, and are rigidly
braced to reduce sound levels and losses.
Other core construction benefits include:
●● Magnetic flux densities, kept well below
saturation point
●● Surfaces of the core, clamps and tie

Enclosures

Enclosures are suitable for lifting, jacking,

been enhanced to combat caustic

made to extend the enclosure, add bottom
plates, add end sheets and/or include
special cutouts for specific applications.
Accessories
Temperature monitor and fan
controller
The controller can display the operating temperature of windings, start and shut off
the cooling fans and provides alarm/trip signal (normal open voltage-free contact),
ensuring effective monitoring and protection of the transformer.
The PT100 sensors are inserted into each LV winding to transmit temperature signals,
which can be displayed on the controller panel.
Main functionality:
●● Set alarms and trip temperature levels
●● Record the maximum temperature in non-volatile memory
●● Send audible over-temperature alarm, alarm signal and trip signal
●● Start and stop fans automatically or manually
●● Provide communication interface (optional)
Cross flow fan
The low noise cross flow fan reduces
the winding temperature, enhances the
overload ability, and prolongs the service
life of the transformer.
The rated power can be increased by 2540% when forced air-cooling is used.
