In the steel, metal and foundry industries, Induction equipment are being used to melt or heat different metals. This induction furnaces operate at high power, high voltage and high current. This high electrical power passes through semiconductor devices, capacitor, inductor, several copper busbar, water cooled cable, induction coil. As very high current passes through all different component it get heated up. to cool this component we have to provide water cooling or in other sense we have to pass water through these component, But this component carry very high voltage so we have to flow non conductive-distilled water and also the rubber hose, which used to supply water must be non conductive.
So for induction equipment rubber hose require following specification
Rubber must be carbon free
non conductive, very low leakage current at high voltage
must withstand operating pressure
long durability–synthetic rubber having long durability
operating temperature more than 120 °C
Good flexibility to accommodate small band
good abrasive strength to protect from external wear and tear
