This paper introduces a new axial slot structure of piece-style slip-ring and the process route of the self-lubricating multi contact brush. The performance test of the high current slip-ring is also carried out. By integrating silver graphite contact into the corner of the piece-style connector, the requirements of self-lubricating, high-current, and long life of the brush are realized. The current transfer capacity of the slipring reaches 1 kA. The processing technology of the self-lubricating multi contact brush lays a foundation for the engineering application of high current slip-ring.
