Compound Slip Ring (photoelectric, liquid, gas)

  • The photoelectric and liquid (gas) compound slip ring is used between the rotor and stator for transmission of various signals and liquid (gas) medium simultaneously.
  • Our compound slip ring can adopt radial direction integration with high concentricity and compact size.
  • Our compound slip ring can adopt axial direction integration with easy and convenient disassembly and maintenance.
  • High speed photo signal transmission and high bandwidth, where WDM technology can be adopted.
  • Our compound slip ring ensures there is no leakage of signal transmission and no electromagnetic interference. It is in a good position to realize long distance and multi-channel bi-directional transmission.
  • It adopts non-contact transmission of the photo signals, without friction wearing so to realize long working life.
  • The photo signal transmission does not produce any electric spark and it can be used in hazardous environment such as combustible environment or explosive environment.
  • The liquid (gas) channel uses special sealing according to different transmission medium, working pressure and working environment to ensure long working life.
  • It is designed to avoid crossed contamination when there are different mediums transmitted in the liquid (gas) channel.
  • Compact structure with small size, easy for installation.
  • Photo signal transmission channel allows bi-directional transmission with low insertion loss and strong anti-interference capability against Electro Magnetic Interference (EMI).
  • The liquid (gas) channels are designed to avoid leakage with high reliability.
  • It is able to integrate two or more transmission mediums.
Typical Applications:
  • Radar system.
  • Ships and vessels.
  • Heavy Industry.
Customized Options:
  • Outline dimensions.
  • Installation size and installation mode.
  • Materials of housing.
  • Surface treatment.
  • Electric connection (wiring and connector) and location.
  • 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.
