The water cooled cables are the only flexible part of the secondary electrical system. The water cooled cable generally consists of multiple copper wire strands.
The water copper cable is covered with a rubber hose. Main parameters for the water cooled cables sizing are; Current density, Water cooling flow rate, Bending Radius, Cable length.
Water cooled cables are obtained by placing the copper conductors inside hose. And they should have pressing cable lugs(heads) at the ends.
