Abstract :
The insulation between the heater wire and the cathode of electronic tubes of the indirectly heated cathode type is required to conduct heat while maintaining high electrical resistance at operating temperatures. By means of cathode-ray oscillograms the effects of operating temperature, heat treatment, and impurities upon the electrical conduction of the commonly used insulating materials are shown in this paper.
