Description:
▲ High power slip ring is mainly installed in the rotary center of the equipment to transmit large current and various signals between two counter rotating platforms.
▲ Generally applying multi-points contact form of gold alloy brush bundle for under 300A current transmission; For more large current application using silver graphite brush block with character of low contact resistance, low electrical and mechanical wear rate and low temperature rise.
▲ Full sealing for inner shaft and electric seal between rings is adopted to ensure insulation reliability under harsh environment
▲ the electric sealing structure is applied to effectively isolate and shield the channels between high power and signal.
