Gas insulated transmission lines in railway galleries
2003 IEEE Bologna Power Tech Conference Proceedings,, 2004 This paper deals with the possibility of installing a double-circuit gas insulated transmission line (GIL) in the pilot tunnel of the planned new railway galleries Bolzano (Italy)- Innsbruck (Austria). This EHV transmission line could represent a new fundamental step in reconstructing the transnational networks. The high GIL power ratings together with

Gas insulated transmission lines
IEEE Power Engineering Review, 2000Gas-insulated transmission lines (GIL) are a further development of the tubular conductor intended for long distances and are especially suitable for connecting conurbations to centers of power supply. They are also as "invisible" as ordinary power cables as well as having a number of other advantages.

Solution of coupled electromagnetic and thermal problems in gas-insulated transmission lines
IEEE Transactions on Magnetics, 2003Gas-insulated high-voltage and extra high-voltage transmission lines are a new technology for transmitting high-power ratings over long distances. A previous paper was devoted to predict the current distribution along with the external flux density in this multiconductor system, highlighting its proximity effect.

Heat Transfer Characteristics of Gas-Insulated Transmission Lines
IEEE Power Engineering Review, 1986This paper reports on an investigation of the heat transfer characteristics of GILs under constant temperatures and under changing temperatures influenced by solar radiation and wind. It was verified that values calculated by our heat transfer formulas coincided well with measured values both for current-induced temperature rise of the conductor and ...

Operating Parameters of Compressed-Gas-Insulated Transmission Lines
IEEE Transactions on Power Apparatus and Systems / Technical Operations Committee, 1969This paper describes a method to choose the physical parameters of a compressed-gas-insulated cable. A calculation of the power rating, losses, and critical length is carried out based on the physical parameters. This calculation is then compared with the ratings of pipe-type cable and is shown to be superior particularly for high-voltage, high-power ...
