Underground Construction Technology International Conference & Exhibition

With the increase in demand and the challenges posed by the design and installation of high voltage (HV) and extra high voltage (EHV) cables in dense urban and other congested right of ways, structures such as tunnels and bridges for multi-purpose use are becoming an attractive option. Cigre (International Council for Large Electrical Systems) formed a working group to develop engineering guidelines on Cable Systems in Multi Purpose or Shared Structures. A summary of the engineering guidelines will be provided. Electrical and civil engineers may design, build, operate and maintain shared or multipurpose structures to last up to 75 to 100 years. However, it shall be recognized that the organizations assigned to manage and maintain these novel structures can change warranting a careful examination of all the aspects included in these Cigre' guidelines.
