Abstract
The capacitance and diameter-over-dielectric of successive sections of a conductor having a layer of cellular plastic insulation extruded thereon are monitored continuously. The monitoring provides a continuous indication of the capacitance and the diameter with respect to the percent expansion of the cellular plastic insulation and the weight of the insulation per unit length of the conductor. This facilitates the regulation of process variables to maintain the capacitance and diameter-over-dielectric within acceptable ranges of values.
