METHOD AND APPARATUS FOR THE ELECTROLESS PLATING OF A METAL SURFACE OF A HOLLOW CONDUCTOR, HOLLOW CONDUCTOR, STATOR BAR OF AN ELECTRIC MACHINE AND STATOR WINDING ARRANGEMENT OF AN ELECTRIC MACHINE

摘要

An electroless plating method and apparatus enable electroless plating of hollow conductors and stator bars over an extremely wide range of sizes, in particular such that the relation between length (L) and inner equivalent diameter (IDe) of said hollow conductors ranges up to 5000:l. Furthermore, the method and apparatus are applied to mounted stator bars whereby there is no need to disassemble the hydro- or turbogenerator hence avoiding prolonged outages.
