Product Overview
INGIANT TECH’s FHS190-12-20214 is a precision-engineered 12-circuit slip ring designed for wind turbine pitch control systems. It transmits high-power electrical energy, control signals and bus communications continuously between the rotating hub and stationary nacelle to enable accurate pitch adjustments. Built for harsh onshore and offshore conditions, it features an internal heater, IP65 protection and military-grade reliability suitable for 1.5MW–3MW turbines.

Core Product Advantages

• Optimized circuit configuration for wind turbine pitch systems: Multi-circuit layout with five high-power 80A/400VAC channels for pitch motor drive, three 2A/24VDC safety-chain channels and four 2A/24VDC CANopen signal channels to separate power, safety and communication paths.
• Integrated sensor & encoder support: Pre-installed speed sensor and encoder interface (examples referenced) for real-time pitch position feedback and reduced external wiring.
• Durability in extreme environments: IP65 dust/water protection, resistance to salt spray, vibration and temperature extremes; internal heater prevents condensation and icing; precious-metal contacts ensure low dynamic resistance and long service life (>20 million rotations design target).
• Robust mechanical design & installation features: Adjustable overall length (410–540 mm), 190 mm through-hole diameter, modular wiring outlets, pre-terminated cable glands and detachable accessories for simplified integration.
• Customizable & standards-aligned engineering: Circuit, voltage/current ratings, dimensions and communication protocols (PROFIBUS, EtherCAT, PROFINET) can be configured to match specific turbine models; manufactured under strict quality controls and aligned with wind-industry specifications (IEC 61400).

Application Scenarios

• Wind turbine pitch control systems: Compatible with 1.5MW–3MW onshore and offshore turbines.
• Renewable energy equipment: Hub-nacelle interconnection, pitch drives and rotary power transmission in wind farms.
• Industrial rotating equipment: Low-speed, high-reliability power and signal transfer in harsh rotating installations.
