APPARATUS OF CONTROLLING ELECTRIC POWER FOR ELECTRIC FUSION PIPE FITTING USING CONDUCTIVE POLYMER COMPOSITE AND METHOD THEREOF

摘要

Provided is an electric power control apparatus of an electrofusion coupling pipe using a conductive polymer composite as a heating element and a method of controlling electric power using the same. The electric power control apparatus supplies electric power to the electrofusion coupling pipe using a conductive polymer composite as a heating element to detect resistance variation of the conductive polymer composite and then controls electric power supplied to the synthetic resin pipe electrofusion coupling pipe on the basis of the detected resistance variation.
