AI Technical Summary
The current-conducting slipper material of existing segmented insulators has an inherent contradiction between conductivity and wear resistance, resulting in severe wear, frequent arcing, and worsened poor contact in humid environments, affecting the safety and stability of rail transit.
By using copper-carbon fiber composite material, a copper-carbon fiber composite friction working surface is formed by opening directional through grooves on the friction working surface of the copper matrix and embedding carbon fiber inserts. Combined with adhesive bonding, the structural design and process flow are optimized to achieve an improvement in overall performance.
It significantly improves the wear resistance and structural stability of the guide shoe, extends its service life, avoids local overheating, adapts to high-speed, high-pressure and high-wear conditions, and reduces equipment maintenance costs.
