Premium-Quality Wind Turbine Inner & Outer Cover Sets: 20-Year Durability, Corrosion-Resistant Design

Overview of Wind Turbine Inner And Outer Cover Set

The wind turbine inner and outer cover assembly is a core protective component for wind turbines, specifically designed to protect key components such as the generator and gearbox. Comprising an inner and outer cover, a highly reliable sealing system, the assembly effectively isolates against harsh environmental factors such as dust, rain, and salt spray through a multi-layered protective structure. It also provides shock resistance, electromagnetic interference protection, and heat dissipation and ventilation. The modular design accommodates onshore and offshore wind turbines of varying power levels (1.5MW-15MW), meeting IP56 and higher protection standards, significantly improving operational stability and maintenance efficiency.

Features of Wind Turbine Inner And Outer Cover Set

All-Environment Adaptability

• Dual Onshore/Offshore Versions: The offshore version utilizes 316L stainless steel fasteners and marine-grade anti-corrosion coating to resist salt spray corrosion; the onshore version features an optimized dust-proof structure, suitable for extreme environments such as deserts and plateaus.
• Intelligent Temperature Control: Integrated phase change material (PCM) or ventilation valves automatically adjust internal temperature to prevent condensation.

High-Reliability Seals

• Three-Level Protection Mechanism:
  • Primary Seal: Labyrinth grooves block large particles;
  • Secondary Seal: Silicone rubber O-rings provide airtight isolation;
  • Emergency Seal: Backup seal grooves automatically trigger if the primary seal fails.
• Online Monitoring Port: Reserved mounting position for a pressure sensor for real-time monitoring of the sealed chamber status.

Lightweight and High Strength

• Topology Optimized Structure: CAE simulation reduces material redundancy, increasing the outer cover strength by 20% and reducing weight by 15%.
• Composite Materials: Optional carbon fiber-reinforced outer cover is 40% lighter than steel and offers three times the fatigue resistance. Quick-Maintenance Design
• Single-side opening mechanism: Utilizing hydraulic assistance or a gas spring, single-person operation is simple.
• Modular seal: Snap-on installation reduces replacement time from 2 hours to 15 minutes.

Application of Wind Turbine Inner And Outer Cover Set

• Generator Protection: Covers the doubly-fed/direct-drive generator, preventing coolant leakage and external contaminants.
• Gearbox Seal: Forms a sealed cavity at the connection with the main shaft, extending the gear oil change interval to 8 years.
• Converter Isolation: Optional conductive rubber gaskets shield electromagnetic interference (EMI) and ensure stable converter operation.
