            Abstract : 
With the commissioning of the 500 m long gasinsulated transmission line (GIL) at the Geneva Airport, Siemens is the first manufacturer of the second generation GIL world-wide. This project concluded successfully the recent development works on this future transmission technology. The redesign of GIL brought a reduction of costs by more than 50 %. The main changes were replacing pure SF6 by a gas mixture of N2 and SF6 as insulating medium and by adopting pipeline laying methods into the laying process.
