Power Slip Rings are suitable for high power AC or DC transmissions. Silver rings are coupled with graphite brushes. Silver Graphite contacts can handle very high temperatures potentially generated by overloads. Excellent dielectric properties of the insulation prevents from shortings, even if humidity appears. Power Slip Rings are hermetically sealed.
Thanks to their rugged design, operation is extremely reliable and maintenance free up to several hundred million rotations without components change or lubrication.
They can be combined with other types of rotary joints such as FORJ, Hydraulic or Hyper Frequency.
