Advancing Aluminum Brazing Technologies for Reliable Connections in Wind Turbine Generators
The increasing adoption of aluminium windings as a strategic alternative to copper in wind turbine generators introduces significant challenges in electrical joining, material compatibility, and long-term operational reliability. Robust interconnection technologies are critical to ensuring performance stability under demanding service conditions.
This presentation examines the technical considerations associated with aluminium–aluminium and copper–aluminium brazed joints in large-scale generator applications. Emphasis is placed on metallurgical interactions, joint design optimisation, and process parameter control, and their influence on electrical conductivity, mechanical strength, and durability under cyclic thermal and mechanical loading.
Findings from stator manufacturing trials and prototype validation studies will be discussed to illustrate performance assessment methodologies and considerations for industrial scalability.
