Abstract In our country, we’re vigorously developing EHV and UHV transmission technology. The first step of carrying out EHV transmission is that, we must have the advantage EHV and large-current products which either have independent intellectual property rights. Because of many advantages, Gas insulated transmission lines were used in a large number of Engineering. BUS is the main electric loop of GIL, so the design of BUS with high performance and reliability is the foundation of designing 550kV GIL. This paper introduced how to design shells and conductors according to the voltage and insulation level. Also we verified the rationality of the structure by simulation of the electric field, analyzed and calculated the internal fault arc in BUS and the tests.
