High Current Slip Rings

Cosmau's high current, multiple contact SRF slip rings can handle hundreds of ampers. In applications like wind turbines, rotary turntable molding machines. conventional slip ring contacts suffer from arcing, friction and inevitable degradation of electrical performance. The SRF operates at 95% energy efficiency with no arcing or breaks in the flow of power, maintaining consistency and quality of power as it’s transmitted. This greatly improves product quality and eliminates maintenance costs.

  • High-current/multi-contact
  • Continuous-duty cycle operation
  • Eliminates arcing
  • Contact materials:precious metal + gold plating which ensures abrasion resistant and anti-Oxidant for long working life
