Through-bore slip rings ,the center hole can pass through the drive shaft, gas-liquid passage; it can also integrate high frequency, fiber, encoder, wave guide, gas and liquid and other joints. The use of advanced fiber brush ensures reliable contact under extremely low friction. The center hole is available from 0 to 1000mm. The current is from mA to 5000 amps. The voltage can be up to 10000 volts, which can fully meet different needs of transmission.
