Large-current Slip Ring

LPA series is a cluster of slip rings characterized by high current transmission up to 2000A (peak current). It adopts state-of-the-art technology with special design to meet different requirements of multifarious fields. Moreover, the large welding strength of its base between support plate and foot is validated by the simulation test. Strictly speaking, it is a customer-specific part designed exclusively for special application where high-current transmission is required particularly.
