The role of water-cooled cables
The function of the water-cooled cable is to connect the medium frequency power supply and the induction coil. It is formed by twisting each diameter Φ0.6-Ф0.8 copper wire. For a 500 kg medium frequency electric furnace, the cable cross-sectional area is 480 square millimeters, and for a 250 kg medium frequency smelting electric furnace, the cable cross-sectional area ranges from 300 to 400 square millimeters. The outer hose of the water-cooled cable uses a pressure rubber hose with a pressure resistance of 5 kg, which is filled with cooling water. It is a part of the load circuit. It is subjected to tension and torsion during work. It tilts with the furnace body and twists, so it is easy to be flexible after a long time. The connection is broken. The breaking process of the water-cooled cable generally involves cutting off most of the parts first, and then quickly breaking the unbroken part during high-power operation. At this time, the medium frequency power supply will gen...
