APPLICATION OF LONG HIGH CAPACITY GAS-INSULATED LINES IN STRUCTURES

This brochure gives information on the application of long high capacity Gas-Insulated Lines (GIL) in structures like bridges or tunnels. It is written as a guide for technical experts involved in all aspects of GIL, but also can be used for general information on GIL technology. Basic information is included about published doc-uments, the properties of insulating gases, technical data, and standard design dimensions and specifications. It explains the planning steps and requirements con-cerning route planning and the possibilities and limits given by the GIL. The existing GILs in structures have been identi¬fied world-wide for tunnels, above ground installations, directly buried installations, and bridges; for tunnels and bridges specific requirements, e. g. seismic, electromag¬netic fields and grounding, are explained and discussed for different types of bridges and tunnels. Project execution and the handling of large scale pro-jects including the operation, maintenance and repair process are covered, as well as life cycle assessment, safety analysis and detailed cost analysis.
