Segmented conductor rail expansion joints: BYDRecent Research Landscape

Mechanical wear and electrical arcing in high-speed transit lead to frequent maintenance downtime and power loss. These innovations control the cross-sectional profile and mounting alignment to ensure continuous current collection.

What technical problems is BYD addressing in Segmented conductor rail expansion joints?

Surface traction loss

(54)evidences

Ice accumulation and low friction levels on conductor rails compromise electrical contact and vehicle traction. Mitigating these environmental hazards prevents power interruptions and braking failures.

Discontinuous track guidance failure

(23)evidences

Physical obstructions and misalignment during the transition of traveling wheels across rail segments. Eliminating these failures ensures continuous vehicle motion and prevents structural damage during turnout operations.
