The gearbox is an important transmission component in the wind turbine, and its internal hose structure is essential for the normal operation of the gearbox to transmit media such as hydraulic oil or lubricating oil. KUNGFLEX hoses enable the tightness and reliability of thin oil lubrication systems in gearboxes.
The wind turbine presses the hydraulic oil into the hydraulic cylinder through the hydraulic pump, so that the piston moves, and the pressure is transmitted to the control valve through the hydraulic pipe (including the hydraulic steel pipe), so as to realize the control of the blades.

In wind turbines, the yaw system, pitch system, and brake system are the three core hydraulic systems that ensure the safe and efficient operation of the units. Hydraulic hoses, acting as the "blood vessels" of these systems, play a key role in transmitting hydraulic power and controlling actuators.
The yaw system is responsible for driving the nacelle to follow the wind direction. Its hydraulic brake hoses need to have excellent pulse resistance and fatigue resistance to ensure stability and reliability during frequent braking. Studies have shown that factors such as hose length and inner diameter directly affect the response performance and control accuracy of the yaw brake system.
The pitch system adjusts the blade angle through hydraulic cylinders to optimize wind energy capture and reduce mechanical load. Pitch hydraulic hoses must endure continuous dynamic bending in the rotating hub, requiring very high flexibility and torsion resistance, while also adapting to temperatures as low as -40°C.
The brake system (high-speed shaft brake) is the final safeguard for the safe operation of wind turbines. Brake hydraulic hoses must have low expansion, high burst resistance, and fast response characteristics to ensure instant braking in emergency situations.
