Passivation of hollow copper strands in a stator water cooling system

摘要

A system (200) for passivating a plurality of hollow copper strands (202) in a stator water cooling system including; a first storage tank (204) containing a cleaning solution, a second storage tank (206) containing rinsing water; a third storage tank (208) containing a passivation solution; a plurality of conduits (210) connecting the first (204), second (206), and third (208) storage tanks in a closed loop with the plurality of hollow copper strands (202); and an alkaline pump (212) for pumping the cleaning solution, the rinsing water, and the passivation solution through the closed loop.
