Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to a water-cooled cable for intermediate frequency furnace with a spring core. Background Technique

[0002] The intermediate frequency furnace is a power supply device that converts 50HZ alternating current of industrial frequency into intermediate frequency (above 300HZ to 1000HZ). It rectifies three-phase industrial frequency alternating current into direct current, and then converts the direct current into adjustable intermediate frequency current, supplying intermediate frequency alternating current flowing through the capacitor and induction coil. High-density magnetic lines are generated in the induction coil and cut the metal material placed in the induction coil, generating a large eddy current in the metal material. Special cables are used in the intermediate frequency furnace to ensure safe use. However, the existing cables have deficiencies, such as low cooling effect of copper stranded wires, poor high-temperature resistance, and short service life of the cables.
