Service

Our industrial busway system played a key role in the excavation of Shanghai Metro Line 13's tunnel boring machine (TBM). TBMs require highly efficient use of space, and the control cabinets involved in the project had multiple circuits, necessitating compact and tidy industrial control cabinets. Our uniquely designed busway system allowed easy maintenance and ensured fast response times during construction, significantly improving the stability of the excavation process. Shanghai Metro Line 13, spanning 5.254 km, began operation in 2018.
