Slip RIng in Wind Turbine


Modern fans require transmission of power and control signals from the hub to the blades through slip rings to drive and control the blades , and they must be maintained in harsh environments (such as remote, low temperature, seawater and oil corrosion, etc.) It must ensure that the quality of the slip ring is reliable and stable. JINPAT is the earliest slip ring manufacturer in China to develop wind turbine slip rings and realize mass production.
