Cables

are water-cooled in induction furnaces and used as cooling water return lines. In the case of low performances, cables can also be used as water feed lines. The copper conductors have 35 or 50 mm2 copper cross-sections. For medium fre- quency the individual conductors have a paint insulation, although this offers no benefits for mains frequency. The electrical connections can take the form of flat connections or clamp-ring connections.
