 With
nearly 70 years in the business of manufacturing transformers as well as
rebuilding our competitors' units, Ward has developed the knowledge of
what works best on nearly any application. Only the best components
and materials are used in our transformers; this is in conjunction
with quality precision engineered designs. Our designs are first
computer-engineered, then calculations are carefully generated by hand
to verify that the transformer will meet or exceed required performance
criteria. We always build our units on a conservative design and
not to the very edge of the rating.
 Our
windings are not the industry standard of a film-coated wire alone.
Whether aluminum or copper conductors are used on the primary, we use a
Kraft paper insulation which is double-wrapped over the conductor.
This is used to minimize the chance of burrs in the standard wire coating
causing a turn-to-turn fault. Our low voltage conductors, in most
applications, are of a sheet winding. The use of sheet conductor
on the secondary of the transformer helps to provide the greatest short
circuit strength. We incorporate a thermally up-rated epoxy
coated diamond design Kraft paper insulation. When the coils are
heated, the epoxy flows over the coil, binding the conductor and the insulation
together. This creates the best design for helping to withstand the
abuses associated with industrial applications.
Ward can offer quick response
to your application needs. Since we are a small company, the usual
red tape associated with a large company does not get in the way.
By the time most companies can produce reference drawings, we can already
be winding the transformer. Usually within hours after receipt of
an order, the first stages of production are in motion.
Finally, it is noteworthy
that Ward has not had an in-the-field failure of a liquid-filled transformer
core and coil assembly in over 7 years. The attention to providing
quality products backed up by our group of trained technicians is your
assurance of the best transformer on the market today! |
