BC1 series rotary arm sliding suitable for porcelain rheostat in voltage does not exceed 500 volts of industrial electrical equipment voltage and current regulation and adjustment of DC voltage generator and DC motor speed adjustment. Sliding rheostat by Kang copper or nickel chromium wire as material resistance around the circular ceramic skeleton, resistance materials except the sliding contact surfaces are coated resistance to high temperature enamel paint and adhesive on the chassis of the ceramics, distribution center to a rotating shaft to drive the brush holder and brush to get change in resistance value. Opening and protection type rheostat to separate two kinds, namely the protection type rheostat with protective metal box shell, and with hand wheel adjustment.
Two, model meaning
* order rheostat resistance porcelain specifications such as breaking to put forward specific requirements
