10T T-type OCS crossing (160-250km/h)
copper alloy T-bar structure L1800/2500
Specifications
| Model | 10T |
|---|---|
| Standard | TB/T 2075 series and OCS crossing installation technical conditions |
| Design Speed | 160~250km/h (pertype) |
| Operating Temperature | -40℃~+70℃ |
| Altitude | <4000m |
| Materials | Copper alloy limiting tubes, aluminium alloy positioning parts, stainless steel fasteners |
| Installation | Installed where two contact wires cross in turnout sections; S/T/Y types chosen by turnout layout |
The T-type OCS crossing uses a copper alloy T-bar structure, relatively complex, with dropper wires, U-shackles and current-carrying rings. The dropper wire is JTMH10 copper alloy stranded wire; fasteners are 06Cr19Ni10 stainless steel.

Performance
Operating Conditions
For station turnout sections, ensuring smooth pantograph transition between two contact wires.
Mechanical Performance
Limiting-tube clearance is precisely controlled by crossing model, eliminating hard points and pantograph-striking risk; all hinged parts rotate freely.
Electrical Performance
Reliable equipotential bonding avoids potential-difference burning at crossings.
Applications
Station turnout areas:
T-type crossings keep pantograph transition smooth at station throat turnouts.
High-speed mainline turnouts:
T-type crossings eliminate hard points and contact loss on high-speed turnouts.
Depot lines:
T-type crossings offer flexible arrangement in dense depot turnout areas.
Junction connecting lines:
T-type crossings adapt to complex turnout geometry on junction lines.
