ABSTRACT:
An apparatus for and method of heat curing elastomeric electrical insulation on a central electrical conductor of an electrical cable is provided and the apparatus includes an outer housing which is adapted to contain means for curing the exterior portion of the insulation from its outer portion inwardly and an electrical induction coil for curing the insulation from its inner portion outwardly. The coil is supported concentrically within the housing with the coil being adapted to receive the conductor therethrough with its insulation thereon and the coil serves to heat the conductor which in turn transmits heat to the inner portion of the insulation to provide the heat curing thereof from the inner portion radially outwardly. A magnetic flux shield is provided between the housing and the coil and serves to provide a path of least resistance for the lines of magnetic flux generated by the coil to thereby assure efficient operation of the induction coil yet without detrimental heating of the outer housing.
