Yangzhou Shouxihu Tunnel project

Sfere3000 electric power monitoring system

Yangzhou Shouxihu Tunnel is 3.6 km long and designed as a single-tube, double-layer, two-way and four-lane tunnel. The shield section of the main tunnel was built by using a slurry shield machine with ultra large diameter (14.93 m) in the world to tunnel through full-section hard plastic clay formation of more than 1200 m long. This tunnel overcomes the global shield tunneling construction problems such as tunneling through the full-section hard plastic clay formation. Several technologies used in the project have reached the international advanced level and the project won the honorary title of "Environment-friendly Demonstration Project of National Construction Industry".

Yangzhou Shouxihu Tunnel was built under the control of the Sfere3000 electric power monitoring system manufactured by Jiangsu Sfere Electric Co., Ltd. to achieve many functional requirements such as system operation monitoring, remote control and system parameter settings, and important circuit load trend analysis so as to meet requirements of the project for power supply and distribution systems in terms of safety, reliability, stability, practicality and openness.
