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.
