This brochure gives information on the application of long high capacity Gas-Insulated Lines (GIL) in struc-tures 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\uacfied world-wide for tunnels, above ground installations, directly buried installations, and bridges; for tunnels and bridges specific requirements, e. g. seismic, electromag\uacnetic 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
