Short Description- Model: FHS135-30-30332 wind turbine pitch slip ring.
- Hybrid Design: 5 circuits of 80A/400VAC power integrated with 25 control and shielded signal circuits.
- Rugged Build: IP65 protection and -40°C to +80°C operating range for harsh environments.
- Premium Contact: Precious metal contacts with beryllium copper brushes; dynamic resistance <10 mΩ.
- Modular Service: Independent power and signal rings enable on-site replacement to reduce O&M time and cost.
- Compatibility: Customizable for 2.0–3.0 MW turbines (examples: Goldwind, Sinovel, Mingyang).
Product DetailThe FHS135-30-30332 transmits power and control signals between the stationary nacelle and the rotating hub to enable real-time blade pitch control and emergency feathering. Engineered for 2.0–3.0 MW class turbines, the unit combines high-current transmission and low-noise data channels in a compact, serviceable housing suitable for onshore and coastal installations.
Key Features- Hybrid Power & Signal Transmission: 5×80A @ 400VAC for pitch motor drive plus 25 auxiliary power, control and shielded communication circuits (CANBus/Profibus compatible).
- Industrial-Grade Durability: IP65 protection and -40°C to +80°C operating range; designed to resist dust, salt spray and severe vibration.
- Premium Contact System: Precious-metal plated rings and beryllium copper brush wires deliver dynamic resistance variation <10 mΩ for stable signal integrity.
- Modular & Serviceable: Power rings and signal rings are independently replaceable to minimize downtime.
- Anti-EMI Design: Physical separation of power and signal paths reduces electromagnetic interference for reliable communication.
- Heavy-Duty Connectors: Harting-style industrial connectors on rotor and stator sides for secure, rapid maintenance.
