Offshore Wind Turbine Pitch Slip Rings
Offshore wind turbines face extreme challenges such as temperature fluctuations, high humidity, high altitudes, salt spray corrosion, vibration, and harsh weather conditions. These factors make maintenance difficult and costly. The introduction of NBG's less maintenance slip rings effectively addresses these pain points, helping turbine manufacturers and owners reduce maintenance costs and minimize turbine downtime. As a result, NBG's slip rings are highly favored by leading turbine manufacturers.

Onshore Wind Turbine Pitch Slip Rings
Onshore wind turbines must operate under complex conditions such as extreme temperatures, high humidity, high altitudes, vibration, and harsh weather. These environments demand high signal transmission quality from slip rings. NBG's onshore pitch slip rings need less maintenance, highly reliable, and feature exceptional longevity, making them one of the best-selling and most trusted models in the wind power industry.
