Taihu Tunnel
Suzhou China
Taihu Tunnel, as the longest and widest underwater tunnel in China, spans 10.79 km in length and 43.6 m in width. It supports a daily traffic flow of over 100,000 vehicles and sets a new benchmark for sustainable transportation.
Siemens provides Taihu
Tunnel with eco-friendly, reliable, and intelligent power distribution
solutions, aiding the tunnel to achieve its carbon neutrality. 400+ Siemens blue GIS – 8DJH 12 switchgears and Siemens NXAirS air-insulated switchgears are equipped and empower Taihu Tunnel.
Eco-friendly technology: Over 400 Siemens blue GIS – 8DJH
12 switchgears, replacing SF6 with clean air, empower Taihu Tunnel to reduce its carbon emission by
8,629 tons CO2, equivalent to planting 560,000 trees, through the switchgears’
life cycle.
Stable power supply:
Siemens NXAirS air-insulated switchgears equipped
on both ends of the tunnel provide safe and reliable power supply.
Intelligent maintenance:
Siemens 7SJ686 relay protection serves as the tunnel's digital guardian. By
collecting data from power distribution equipment, 7SJ686 can monitor the
operation status and pre-diagnose the potential issue.
