FHS135-30-30332 Hybrid Pitch Control Slip Ring for Wind Turbines

In wind turbine applications, the pitch slip ring is the critical link that transmits power and control signals from the stationary nacelle to the rotating hub, enabling real-time blade pitch adjustment for optimal energy capture and emergency feathering. Our FHS135-30-30332 is purpose-engineered for 2.0–3.0 MW class wind turbines, integrating high-power transmission and low-noise signal communication into a single ruggedized unit.

Key Features

Hybrid Power & Signal Transmission — 5 circuits × 80A @ 400VAC for pitch motor driving, plus 25 auxiliary power, control and shielded communication circuits (CANBus / Profibus compatible)
Industrial-Grade Durability — IP65 protection with -40°C to +80°C operating range, resistant to dust, salt mist, and extreme vibration
Premium Contact System — Precious metal plated rings with beryllium copper brush wires; dynamic resistance variation <10 mΩ for ultra-stable signal integrity
Modular & Serviceable — Power rings and signal rings are independently replaceable, dramatically reducing O&M downtime and cost
Anti-EMI Design — Physically isolated power/signal routing prevents electromagnetic interference, ensuring zero packet loss on communication rings
Heavy-Duty Connectors — Harting-style industrial connectors on both rotor and stator sides for secure, tool-free maintenance
