380 kV cable corridor under a city street
Route width reduced 2.4 m
01 · Challenge
An underground high-voltage cable route risked exceeding limits at ground-floor apartments along the street.
02 · Simulation
Comparison of eight laying configurations including trefoil, flat, split-phase and shielded trough variants.
03 · Solution
A trefoil arrangement in a shielded concrete trough with a conductive cover plate.
04 · Execution
Detailed design handed over to the civil contractor with installation supervision.
05 · Result
Compliance achieved with a 2.4 m narrower corridor, saving significant excavation cost.
