A tubular ceramic has two terminals, and is wound with copper wire
or chromium alloy wire to provide the resistance and then coated with
a high temperature, non-flammable resin. After the semi-finished part
is cool and dry, insulation is applied through a high-temperature process
and the mounts are attached.Since the winding is excellent, many
taps can be added, impedance is low and the shape can be altered to
produce many types. DR series is suitable for educational modeling
applications, load testing, industrial machinery, electric power distribution,instruments,automation
control installations, etc. For custom specifications, please contact
us to discuss the details.
