Rendimiento
Condiciones de servicio
For station desvío sections, ensuring smooth pantograph transition between two cable de contactos.
Rendimiento mecánico
Limiting-tube clearance is precisely controlled by crossing model, eliminating hard points and pantograph-striking risk; all hinged parts rotate freely.
Rendimiento eléctrico
Reliable equipotential bonding avoids potential-difference burning at crossings.
Aplicaciones
Station desvío areas:
T-type crossings keep pantograph transition smooth at station throat desvíos.
High-speed mainline desvíos:
T-type crossings eliminate hard points and contact loss on high-speed desvíos.
Depot lines:
T-type crossings offer flexible arrangement in dense depot desvío areas.
Junction connecting lines:
T-type crossings adapt to complex desvío geometry on junction lines.
