Abstract
The increase in demand and the challenges posed by the design and installation of high voltage and extra high voltage cables in dense areas and other congested rights of way, structures such as tunnels and bridges,multipurpose or shared use structures are becoming an attractive option. They offer reduced overall costs, environmental advantages and less disruption during installation, maintenance and replacement of cables and other services. Sections 1 to 5 of the TB review the examples described in section 8 to decide if a shared structure is appropriate. If the decision is to use a shared structure, sections 6 and 7 cover the technical and administrative issues, relative to the design and implementation of such systems. Section 8 is a review of the international experience of HV cables in multipurpose or shared structures. Future trends are summarised in Section 9. A comprehensive appendix embodies the results of the questionnaires on the global use of cables in shared structures. Similar issue for Gas Insulated Lines (GIL) has been reviewed by JWG B3/B1.09 in the TB 351 “Application of Long High Capacity Gas Insulated Lines in Structures”.Pubblicazioni consigliate
