Water-cooled cable's principle introduction

What is water cooled cable for induction furnace? Many equipment will generate heat after long use, even the cable. If the current is large, it will be easy to generate heat. The occurrence of heat will affect the normal work and service life. Water-cooled cable is a kind of cable that uses water to cool down. Because it solves the heating problem, the working strength and capacity of water-cooled cable are much higher than those of ordinary cable.
