Gas Insulated Transmission Lines (GIL) are the safe and flexible alternative to overhead lines and occupy much less space while providing the same power transmission. Because they hardly affect the landscape, and their minimal electromagnetic radiation means they can also be used nearby, or even inside buildings, GIL can be considered for a wide range of applications. They are suitable for providing continuation of underground overhead lines, connecting power plants to the mains, or as a way to save space to connect the main industrial plants to the public grid.
Gas Insulated Transmission Lines (GIL) are a further development of the tubular conductor intended for long distances and are especially suitable for connecting conurbations to power supply centers. They are also as "invisible" as ordinary power cables, as well as having a number of other advantages. The world's first gas-insulated power transmission line successfully completed its field trials with a resistance test in early 1999. The most important goal in developing tubular conductors for long-distance power transmission was to reduce So that it can be used economically over distances of up to several kilometers. This has already been achieved. The system costs of the isolated gas transmission lines developed by Siemens are now only a factor of 8 or 10 above the airlines, below a factor of 30. Now the GIL has reached the order of magnitude to be Accepted by public services If an airline should be placed underground. The basis of this cost reduction was: adaptation of installation techniques similar to those used in oil pipelines; Simplification and standardization of individual components; And the use of a mixture of sulfur hexafluoride (SF / sub 6 /) and nitrogen (N / sub 2 /) gases. In the past, SF / sub 6 / pure has been the most widely used gas for tubular conductors, most of which have been incorporated into substations.
