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:
T-type crossings keep pantograph transition smooth at station throat تقاطعs.
High-speed mainline تقاطعs:
T-type crossings eliminate hard points and contact loss on high-speed تقاطعs.
Depot lines:
T-type crossings offer flexible arrangement in dense depot تقاطع areas.
Junction connecting lines:
T-type crossings adapt to complex تقاطع geometry on junction lines.
