10Y Y-type تقاطع شبكة التلامس (160-250km/h)
المواصفات الفنية
| الطراز | 10Y |
|---|---|
| المعيار | TB/T 2075 series and تقاطع شبكة التلامس installation technical conditions |
| سرعة التصميم | 160~250km/h (pertype) |
| الخامات | Copper alloy limiting tubes, aluminium alloy positioning parts, stainless steel fasteners |
| التركيب | Installed where two سلك التلامسs cross in تقاطع sections; S/T/Y types chosen by تقاطع layout |
The Y-type تقاطع شبكة التلامس consists of a fixing مشبك, limiting guide bar, connecting double-eye etc. in an aluminium alloy tube structure, fixing the سلك التلامس where two contact suspensions cross above تقاطعs. The fixing مشبك is CuNi2Si سبيكة النحاس; galvanized steel parts are Q235B.

| Reference mass | 2.2kg |
| Composition | fixing مشبك, limiting guide bar, connecting double-eye etc. |
| Component materials | fixing مشبك CuNi2Si سبيكة النحاس; galvanized steel Q235B |
الأداء
ظروف التشغيل
For station تقاطع sections, ensuring smooth pantograph transition between two سلك التلامسs.
الأداء الميكانيكي
Limiting-tube clearance is precisely controlled by crossing model, eliminating hard points and pantograph-striking risk; all hinged parts rotate freely.
الأداء الكهربائي
Reliable equipotential bonding avoids potential-difference burning at crossings.
التطبيقات
Station تقاطع areas:
Y-type crossings keep pantograph transition smooth at station throat تقاطعs.
High-speed mainline تقاطعs:
Y-type crossings eliminate hard points and contact loss on high-speed تقاطعs.
Depot lines:
Y-type crossings offer flexible arrangement in dense depot تقاطع areas.
Junction connecting lines:
Y-type crossings adapt to complex تقاطع geometry on junction lines.
