Abstract

As the same concept with GIB, GIL(Gas Insulated Line) has been established and run for the first time in New Jersey, America, in 1972. At the beginning, the installation condition of GIL was complicated and the construction cost was excessive, so it was not economical, but the construction cost was substantially reduced with the use of insulation material which is the mixture of $SF_6$ and $N_2$ Gas in Germany, in 1990s. And also comparing to cable, GIL has lots of advantages, such as being capable of the high voltage transmission, being applied to reclosing and lowering the strength of electromagnetic force, Due to these advantages, GIL is recently accepted in many countries.
