Operating Parameters of Compressed-Gas-Insulated Transmission Lines
IEEE Transactions on Power Apparatus and Systems, 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 ...

AC Compact High Power Gas-Insulated Transmission Lines
2018 IEEE/PES Transmission and Distribution Conference and Exposition (T&D), 2018The AC Gas-Insulated Transmission Lines (GIL) technology for high power underground transmission shows an ever-increasing usage worldwide. Today, the AC GIL transmission technology is entering densely populated areas where the desire for solutions of non-visible transmission lines is high.

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 ...

Underground links by gas insulated transmission lines
APSCOM 2000 - 5th International Conference on Advances in Power System Control, Operation and Management, 2000The concern to reduce the number of increasingly contested power transmission lines has led utilities and manufacturers as ALSTOM to search for new underground solutions. Today, the penetration of power lines into the heart of large cities is seriously hindered by the density of population and urban expansion.

Basic properties of hybrid gas‐insulated transmission lines (H‐GIL)
Electrical Engineering in Japan, 1997The recent trend in electric power consumption shows a steady increase and concentration in large cities and industrial districts. This indicates a strong need for a long-distance and enclosed-type power transmission line with large capacity and high reliability.

Gas insulated transmission lines for high power transmission over long distances
Electric Power Systems Research, 1998The gas insulated transmission line (GIL) is a technology developed for the needs of the 21st century, where huge metropolitan areas need an electrical supply for the public and industry. Natural resources of energy are often far away from metropolitan areas.

Gas insulated transmission lines for high power transmission over long distances
Proceedings of EMPD '98. 1998 International Conference on Energy Management and Power Delivery (Cat. No.98EX137), 2002The gas-insulated transmission line (GIL) has been optimised for the needs of the 21st Century, where high-power transmission lines are needed and overhead lines are often not suitable. It will be used as a power feeder into huge metropolitan areas because energy resources are usually far away from the load centre.

Analysis on Common Faults of Gas Insulated Transmission Line
2020 4th International Conference on HVDC (HVDC), 2020Gas-insulated metal-enclosed transmission line (GIL) is a new type of transmission equipment, which can be used to connect overhead line, GIS, transformers and switchgear in power plants. With the development of UHV transmission projects in China, the amount of GIL projects is increasing year by year, while its faults have been paid more attentions by ...

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 ...
