Preheating conductors in extrusion insulating processes by copper loss method — temperature as a function of current

$15.00

The preheating of copper wire prior to the application of extruded insulation is discussed. The principles of the method are described. The difficulties of determining the heat increase and the results of some analyses of heat increase procedures are outlined. The derivation of the mathematical formulas describing pre-heating are presented.
