The pitch slip ring is mainly a device that provides power for the wind turbine pitch system, transmits control signals and communication functions. It is installed on the low-speed shaft of the gear box that rotates coaxially and at the same speed on the wind turbine hub. It is an important part of the pitch control system! Morteng independently researched and developed silver alloy brush-type pitch slip ring, which has the characteristics of self-lubricating, maintenance-free, strong versatility, and signal transmission without packet loss, ensuring the stable signal transmission on the fan.
