Large Power Slip Ring (Central Electric Collection 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.
  • 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:
  • 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.
  • Surface treatment.
  • Electrical connection (Wiring and connector).
  • Experiment projects.

China TrueSci industrial slip rings provide the solution to transmit electric power and electrical signals from stationary to rotating units in all types of machines like radar system, antenna dishes, revolving cranes, rotating purifiers in sewage or water treatment facilities, carrousels, manipulators, wrapping machines, theatre stages, wind turbines as well as in cable reels. Our fully developed and versatile standard program facilitates to assemble slip ring assemblies with any number of poles. Current ratings up to 1200 A and voltages up to 24 kV are possible. The range in size for the slip ring assemblies starts with 30 mm up to 360 mm diameter and lined up to 100-poles. Slip ring assemblies can be supplied either as open, “non-enclosed” types for special customer adaptations, or totally enclosed with high impact plastic or galvanised steel housing even for hazardous locations. Additional rotating couplings are available for fluids or gases and fiber optic swivels can be integrated.
