10Y Y-type cruce de catenaria (160-250km/h)
Especificaciones
| Modelo | 10Y |
|---|---|
| Norma | TB/T 2075 series and cruce de catenaria installation technical conditions |
| Velocidad de diseño | 160~250km/h (pertype) |
| Materiales | Copper alloy limiting tubes, aluminium alloy positioning parts, stainless steel fasteners |
| Instalación | Installed where two cable de contactos cross in desvío sections; S/T/Y types chosen by desvío layout |
The Y-type cruce de catenaria consists of a fixing abrazadera, limiting guide bar, connecting double-eye etc. in an aluminium alloy tube structure, fixing the cable de contacto where two contact suspensions cross above desvíos. The fixing abrazadera is CuNi2Si aleación de cobre; galvanized steel parts are Q235B.

| Length | 1800mm |
| Clearance | 24~27mm |
| Reference mass | 2.2kg |
| Composition | fixing abrazadera, limiting guide bar, connecting double-eye etc. |
| Component materials | fixing abrazadera CuNi2Si aleación de cobre; galvanized steel Q235B |
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:
Y-type crossings keep pantograph transition smooth at station throat desvíos.
High-speed mainline desvíos:
Y-type crossings eliminate hard points and contact loss on high-speed desvíos.
Depot lines:
Y-type crossings offer flexible arrangement in dense depot desvío areas.
Junction connecting lines:
Y-type crossings adapt to complex desvío geometry on junction lines.
