IP65 Wind Turbine Pitch Slip Ring Replace ER-80/400 2.0G4 for Wind Turbine Pitch System
FHS190-12-20214 High-Performance Wind Turbine Pitch Slip Ring
Product Overview
INGIANT TECH’s FHS190-12-20214 is a precision-engineered 12-circuit slip ring, purpose-built for wind turbine pitch control systems. As a critical rotary connector between the rotating hub and stationary nacelle, it ensures uninterrupted transmission of high-power electrical energy, control signals, and industrial bus communication, enabling precise, reliable pitch angle adjustment for maximum wind energy capture.
Designed to meet the extreme demands of onshore and offshore wind farms, this slip ring integrates built-in heating, IP65 environmental protection, and military-grade reliability, making it the ideal solution for 1.5MW to 3MW wind turbine systems.
Core Product Advantages
1. Optimized Circuit Configuration for Wind Turbine Pitch Systems
- Multi-circuit design: 5 high-power 80A/400VAC channels for pitch motor drive, 3 safety chain 2A/24VDC channels, and 4 CANopen 2A/24VDC signal channels, fully meeting the power, control, and communication requirements of modern wind turbine pitch systems.
- Integrated sensor & encoder support: Pre-installed speed sensor and encoder interface (YTD2IB14Y778, 10000T1KAK2 (25G)) for real-time pitch position monitoring, eliminating the need for additional wiring.
2. Extreme Environment Durability & Reliability
- IP65-rated protection: Fully dust-tight and water-resistant, suitable for harsh onshore and offshore wind farm environments, with resistance to salt spray, vibration, and extreme temperatures.
- Built-in heater: Internal heating system prevents condensation and ice formation in low-temperature conditions, ensuring stable operation in cold climates.
- Precious metal contacts: Ultra-low dynamic contact resistance (<10mΩ) ensures minimal signal attenuation, zero electrical noise, and a service life exceeding 20 million rotations, meeting the 20-year design life requirement of wind turbines.
3. Robust Mechanical Design & Easy Installation
- Adjustable mounting dimensions: Overall length adjustable from 410mm to 540mm, with a 190mm through-hole diameter, compatible with most mainstream wind turbine hub designs.
- Modular wiring outlets: Separate outlets for power, signal, safety chain, and encoder, with pre-terminated cable glands for fast, error-free on-site installation.
- Aluminum alloy construction: Lightweight yet high-strength structure, with detachable lever components shipped as accessories for flexible installation.
4. Customizable & Compliant Engineering
- Fully customizable: Circuit configuration, voltage/current ratings, mechanical dimensions, and communication protocols (PROFIBUS, EtherCAT, PROFINET) can be tailored to specific wind turbine models and OEM requirements.
- Military-grade quality control: Manufactured with strict military-grade production standards, fully compliant with international wind power industry specifications (IEC 61400).
Application Scenarios
- Wind Turbine Pitch Control Systems: 1.5MW to 3MW onshore and offshore wind turbines
- Renewable Energy Equipment: Wind power generation, pitch drive systems, hub-nacelle interconnection
- Industrial Rotating Equipment: Low-speed, high-reliability rotary power and signal transmission in harsh environments
