Large Power Slip Ring (Central Electric Collection Slip Ring)

Description of our large power slip ring:
  • Our large power slip rings are usually installed at the rotary center of the equipment and used to for transmission of high current and various signals between the stationary platform and the rotating platform.
  • The large power slip rings adopt high quality copper-graphite brushes or silver-graphite brushes according to the real application, with least contact resistance and electrical sliding wearing and mechanical wearing. It has very little temperature rising.
  • The low frequency (LF) signal adopts gold to gold contact with least transmission loss for long working life.
  • High current and signal use electric sealing structure to realize high efficient insulation and shielding.
  • Both the rotor and stator have their own independent wiring box, maintenance window and observation window.
Features of our high power slip ring:
  • Compact design, requiring just small installation space.
  • Easy for installation and convenient for maintenance.
  • High concentricity and good capability of anti-tilting.
  • Keep little temperature rising under high current.
  • Reliable and stable under high voltage, with excellent insulation performance.
  • Capable of adapting to various environment such as high temperature, low temperature, impacting, vibration, salt spray, damp heat, and etc.
  • Can be integrated with optical fiber, RF, liquid (gas)  rotary joints.
  • Available with optional accessories of heating and dehumidifying fixture and heat-dissipating fixture.
Typical Applications of our high power slip ring:
  • Ocean and Sea Machinery.
  • Heavy Industrial Machinery.
  • Tunnel Shield Machine.
  • Large Power equipment.
Customized Options:
  • Outline dimensions.
  • Installation size and installation mode.
  • Materials of housing.
