Design Points Of High-Current Conductive Slip Rings

As it’s a high-current device, the primary point are contact material, contact brush and installation way, to ensure the reliability and life of slip ring under the working environment. Another point is installation performance which guarantee a normal installation. Since the slip ring is used in the marine environment, the housing material must be corrosion-resistant stainless steel. The ring and brush are the key components, the surface of conductive ring adpots thick gold plating as an electrical contact material. The brush has the leaf springs brush and a linear spring, which produces high current density and minimal wear, but in bigger resistance.

Based on the above characteristics of brushes, we adopted a number of brush bundles as a final brush. PBT can be used as an insulating material, because it has excellent dielectric properties, chemical resistance, fatigue resistance and lubricating. In the mechanical structure, it’s important to consider the characteristics of high current slip ring, and we need to give full consideration of its electrical insulation, installation maintenance ect. when designing.
