CONTROLLING POLYETHYLENE INSULATED WIRE CAPACITANCE,

Abstract

The need for continuous dynamic inspection of insulated wire during the tandem drawing-insulating manufacturing process resulted in the development of a wire capacitance control system. A servo-controlled bridge measures the coaxial capacitance of the moving insulated wire. Deviations in the coaxial capacitance are detected by comparing the wire capacitance during manufacture to a standard capacitance in adjacent arms of the bridge. The resulting error signal is used to automatically adjust the insulating line speed to hold the wire capacitance within specified limits. Also, the error signal is recorded to provide a continuous record of wire quality. This paper presents the principles and advantages of controlling wire capacitance and its effect on cable capacitance. (Author)
