REX POWER MAGNETICS

Rex Power Magnetics is a Canadian dry-type transformer design and manufacturing
company, headquartered in Concord, Ontario (Greater Toronto Area). Since its
humble beginnings in 1972, Rex has quickly emerged as a competitive and
innovative supplier of high-quality CSA certified and UL listed power magnetic
products for markets in North America and overseas. With over 270 employees, we
offer a broad product line including custom dry-type transformers, reactors,
other magnetic devices, and related components and services. We distinguish
ourselves from the competition by our focus on continual product improvement,
responsiveness, and customer service.




FEATURED PRODUCTS


GENERAL PURPOSE ISOLATION TRANSFORMER

General Purpose Isolation transformers are used to lower distribution voltages
(480 or 600V) to lower voltages (typically 120/240 or 208Y120) for power
distribution within commercial or industrial buildings. These “two windings”
transformers provide the electrical isolation required, and allow for short runs
of high current, low voltage cables, reducing losses in the system, and reducing
costs.

CAST COIL POWER TRANSFORMER

Cast coil power transformers feature primary and secondary windings which are
vacuum cast inside a solid block of epoxy resin. The epoxy resin is introduced
under vacuum in order to penetrate all the spaces within the winding, ensuring a
void free casting with minimal partial discharges. The sold casting provides the
highest degree of protection to the windings, making them ideally suitable for
harsh environmental conditions which include airborne dust & high humidity.
Furthermore, the fiberglass reinforcement which is incorporated into the casting
provides the transformer with the highest mechanical strength which makes it
resilient to short circuit forces.

MINI POWER CENTER

Mini Power Centers combine three individual components, prewired into one NEMA
3R enclosure: a primary main breaker, a single-phase or three-phase dry-type
encapsulated transformer (Type EP), and a secondary distribution load center
with main breaker. Inter-connecting wiring is completed at the factory. Mini
Power Centers are used wherever there is a 480V or 600V distribution system and
loads requiring 208Y/120V, three-phase or 120/240V single-phase.

VPI/VPE POWER TRANSFORMER

Vacuum Pressure Impregnated (VPI) power transformers utilize an open winding
design, where the coil insulation is impregnated with an epoxy resin under
vacuum and pressure, providing the windings a degree of protection against
moisture and dirt, and improving the thermal conductivity of the winding which
reduces localized hot spots. Furthermore, the VPI process removes air voids
which deep within the windings, filling them with epoxy instead. These air
voids, if not eliminated, can lead to higher partial discharges which can damage
the transformer insulation over time, leading to premature failure. For a higher
degree of protection, vacuum pressure encapsulated (VPE) coils can be utilized
which involves repeated VPI and bake cycles
