Gas insulated transmission lines - GIL
2008 IEEE/PES Transmission and Distribution Conference and Exposition, 2004The GIL is a transmission system for the transmission of high power levels over long distances, to solve specific routing or access problems, or as connections in power plants and substations. As a gas-insulated system, the GIL has the advantage of having electrical behavior similar to an overhead line. This is of importance to system operation.

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.

Corrosion protection for gas-insulated transmission lines
IEEE Power Engineering Society Summer Meeting,, 2003For buried gas insulated transmission lines (GILs), a coating against corrosion is absolutely necessary and similar to most other directly buried metallic installations. Active corrosion protection, also called catholic protection, may be added to take care about possible failures of the coating as an additional quality insurance system to the passive ...

Development of a Compressed-Gas-Insulated Transmission Line
IEEE Transactions on Power Apparatus and Systems, 1971Development of Compressed-Gas-Insulated transmission lines for voltages of 138 to 500 kV is described. Design, manufacture and installation are presented. Dielectric and mechanical tests data are given. A 230 kV single-phase outdoor test line of 230-ft length has been installed and voltage and current tests have been initiated.
