Advanced Dielectrics for Gas-Insulated Transmission Lines [Editorial]
IEEE Transactions on Dielectrics and Electrical Insulation, 2018High voltage alternating current (HVAC) gas-insulated transmission lines (GILs) have been successfully used as an alternative solution to overhead lines and cables for more than 40 years. GIL can be laid directly buried, in a passable or non-passable tunnel or on a gantry. GIL solutions offer different advantages, such as high current-carrying capacity,

Technical aspects of gas insulated transmission lines and application of new insulating gases
IEEE Transactions on Dielectrics and Electrical Insulation, 2018This publication gives information about the design, testing and long term experience of AC gas-insulated transmission lines (AC GIL). AC GIL does not include any switching devices such as disconnectors, earthing switches or circuit breakers so that the main electric focus is on the insulation capabilities only.

Modeling of the Electric Field in High Voltage Direct Current Gas Insulated Transmission Lines
IEEE International Conference on Dielectrics, 2022High voltage direct current (HVDC) gas insulated systems are utilized when space is limited. The composite of SF6 gas insulation and solid spacer insulation results in high electric field values in the vicinity of the sheath under DC conditions.

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.

Gas insulated transmission lines in railway galleries
2003 IEEE Bologna Power Tech Conference Proceedings,, 2004This 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

Insulation co-ordination for gas-insulated transmission lines (GIL)
IEEE Transactions on Power Delivery, 2001For the transmission of high power over long distances underground the gas-insulated transmission lines (GIL) are a good technical solution as an alternative to an overhead line and in addition to cables. The GIL has two main advantages: low resistive losses because of large cross section of the conductor and enclosure and low capacitive load because ...
