Directly buried gas-insulated transmission lines (GIL)
PES T&D 2012, 2012Regarding the increasing interest in underground transmission systems, gas-insulated lines (GIL) represent an attractive alternative to cable solutions. Changes in the regulatory framework with respect to planned extensions of extra high voltage (EHV) systems have intensified the demand for underground transmission lines in general.

Handbook for Gas Insulated Substations and Transmission Lines
2012 IEEE Power and Energy Society General Meeting, 2012The Handbook for Gas Insulated Substations (GIS) and Transmission Lines (GIL) will be discussed in a panel session at the General Meeting (GM) of PES in San Diego in July 2012. The original idea for a handbook on GIS and GIL came out of the experiences made with the IEEE tutorials on the same subject which were given more than 20 times around U.S ...

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 ...

2020 IEEE International Conference on Advances and Developments in Electrical and Electronics Engineering (ICADEE), 2020
In an Electrical power system, the generating plants are located far away from the loads and gets transmitted through transmission lines. The transmission line can be an overhead line or underground cable. For the last forty-five years, a new technology GITL has been presented as a substitute for underground cables.

Construction of First Gas Insulated Transmission Line in Japan
IEEE Power Engineering Review, 1981The first commercial gas insulated transmission line (GIL) in Japan, a 154kV system, was completed in one of the substations of The Tokyo Electric Power Company Inc. in July, 1979. Thereafter, a 275kV GIL was constructed in March, 1980. This paper describes the details of the design, installation, and tests of these GILs.

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.

Electric field analysis of insulating spacers for a superconducting gas-insulated transmission line
2018 12th International Conference on the Properties and Applications of Dielectric Materials (ICPADM), 2018An essential component of the new superconducting power cable concept called Superconducting Gas Insulated Line (S-GIL) is the insulating spacer that ensures the position in the center axis of the cylindrical, grounded cryostat. The material choices and the design topologies for the insulating spacers are presented for both the rigid and flexible ...

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.

Application of the world's longest gas insulated transmission line (GIL)
2003 IEEE Power Engineering Society General Meeting (IEEE Cat. No.03CH37491), 2004This paper describes the Shinmeika-Tokai line's design, fabrication and construction. This important power supply line delivers power from the thermal power station to the center of Nagoya via the substation. The entire line is laid in an underground tunnel at the depth of approximately 30 m and which contains curves with a minimum radius of curvature ...
