Beijing Wind Energy Exhibition Introduction

As the global energy transition enters its critical phase, the wind power industry is driving a new chapter of green development through the engines of “offshore expansion, large-scale deployment, and digital intelligence.” At the 2025 Beijing International Wind Energy Conference and Exhibition, Morteng showcased its full range of carbon brushes, slip rings, and brush holders, leveraging cutting-edge technology to ensure the efficient and reliable operation of wind power equipment.

1. Wind Turbine-Specific Carbon Brush: Wear-Resistant and Arc-Resistant, Suitable for Large-Megawatt Units

Addressing the high current density and frequent commutation characteristics of wind turbine operations, Morteng carbon brushes utilize graphene-enhanced electrographite material. This offers superior conductivity and extends wear life by 40% compared to traditional products, enabling stable operation exceeding 20 million revolutions. Their unique arc-suppression design effectively minimizes commutation sparks and reduces arc erosion on commutators. Even in extreme temperatures ranging, they maintain stable contact resistance, perfectly meeting the stringent demands of 10MW+ offshore wind turbines.

2. Maintenance-Free Slip Ring: High-Power Transmission for Offshore Wind Power

Aligning with the trend toward larger, modular wind turbines, Morteng slip rings feature an integrated design enabling simultaneous multi-channel transmission of power, signals, and fluids. This meets the high-power transmission demands of large-megawatt units. With an IP68 protection rating, outstanding salt spray and vibration resistance, and a maintenance-free operational lifespan of up to 40 years, these rings align with the core requirement of “low O&M costs” for deep-sea wind power.

3. High-Precision Brush Holder: Precise Adaptation Ensures Current Balance

Morteng's brush holder features a high-strength aluminum alloy monocoque construction paired with adjustable pressure springs. This design precisely controls contact pressure between carbon brushes and slip rings, ensuring balanced current distribution across multiple brush sets. It prevents localized overheating or accelerated wear caused by uneven pressure. Its modular structure facilitates on-site installation and replacement, significantly reducing maintenance workload.
