Power Transformer –TD
Product Introduction



Specially for CNC and industrial equipment

More than 25 years design and manufacturing experience, specialized R & D team and stringent quality control ensured top-rated product. Specialized in the manufacturing of all kinds of transformer, single phase and 3 phase transformer, auto transformer, automatic voltage regulator and UPS specific transformer, inductor and choke coil. We can also accept custom order design and manufactured to different capacity and specification.



Scientifically reasonable design allowing control of voltage change rate within 1% - 1.5% range

Manufactured of brand new silicone steel sheet of Shin Nippon, Kawasaki, Japan that effectively reduces iron loss, reducing field inrush current and increase efficiency

Made of imported high purity copper wire that minimizes own loss rate and greatly increase effectiveness

Adopt AROMA, Japan improved A type and DOPONT Nomex insulating paper as the main insulating materials and enhanced ventilation and heat sink design to increase the high voltage resisting strength and insulation class and therefore extend the service life.

High efficiency design for more than 97% that effectively reduce stray capacity, leak impedance and inhibit input end noise

Patented appearance design gives elegant and modern look; high power density, compact size and increase space utilization

Adopted K coefficient in measuring harmonic wave ability; specially designed isolated transformer in filtering off tertiary harmonic wave and multiple output isolated transformer filters off 5, 7,17 and 19 X frequency harmonic wave (Optional)

Function Description:


Specific Bobbin
Coil Sorting
Main Body
Specific Grounding

Transformer specific
bobbin developed by
the Company is cap-
able of increasing
production efficiency
and overall beauty

Combine with special
oven, this equipment
can inhibit the noise
of transformer and
increase insulation
effect of transformer

The wire sorting ma-
chine developed by
the Company is to
tidy the coil of trans-
former to increase

Main body is fitted
with wiring terminal
which specifically
marked with various
voltage wiring, which
is specific and clear
Grounding is related
with safety of equip-
ment and person,
which shall have
specific and correct
grounding mechanism
