Slip Rings for Medical Equipment

A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. Slip ring is also called rotary electrical joint, collector or electric swivel. A slip ring can be used in any electromechanical system that requires unrestrained, intermittent or continuous rotation while transmitting power and/or data/signal. Slip ring can improve mechanical performance, simplify system operation and eliminate damage-prone wires dangling from movable joints.

The slip rings adopt the advanced precious metal fiber brush wire technology and unique shielding method to ensure reliable signal, low working voltage, low abrasion, and low loss contacting design, which exactly realize longer life time and free maintenance. Slip rings has been widely used on medical equipment, such as shadowless lamp, CT machine and monitoring machine.

Slip rings for Wind Turbine Generator

The slip ring can be part of a large wind turbine electric pitch control system with the option to integrate hydraulic pitch control systems if required. Modern wind turbines require delivery of power and signals to and from the rotating blades by a reliable rotary union assembly. Obviously the quality of the slip ring is a key determinant in the quality of the overall wind turbine generation system.

Nowadays, around 10 percent of wind turbine slip ring in the market are using fiber brush contact materials. This kind of slip ring only need to be maintained rarely. Another 60 percent of slip ring in the market are made of composite metal brush, normally combined with metal and graphite, they require maintenance frequently.

The remaining 30 percent wind turbine slip ring adopt single precious metal brush, with better performance than above two types. The main reason is that composite metal brush design can wear brush in advance to avoid slip ring attrition. But composite metal brush materials is very sensitive to humidity. If Humidity is lower than 15% or higher than 85%, it could lead to uneven wearing. The other problem is that when it is used for signal circuits, these composite metal brush will occupy a great of space.
