High Current Round Edgewound
These high current round
edgewound resistors handle a
variety of applications includ-
ing dynamic braking, load
banks, motor starting, and
plugging. They are available in
a variety of ohm and current
ratings common to transit use.
A sturdy welded steel frame
supports the refractory insula-
tors. The frame is finished with
a zinc chromate conversion
for corrosion resistance. The
ceramic insulators separate
turns of the resistance ele-
ments from each other and the
frame. The resistance element
is a stainless steel strip, used
for its corrosion resistance,
negligible temperature coef-
ficient, and Ohms per foot vs.
current carrying capacity. The
resistance element is created
by edge-winding a stainless
strip into a continuous coil of
the proper length. Zinc plated
terminals welded to the resis-
tance element complete the
assembly.
