In this paper

the world’s first high-level layout of steam turbine generator unit in Jinjie power plant is taken as the research object.Due to the influence of the form and characteristics of the unit

the generator to the main transformer needs to be arranged with high sag and long-distance enclosed bus.In the application process

the analysis and research on the technical problems in many fields such as

radiation and heat dissipation

stress stress

should be strengthened

and through the analysis of the weak points

the corresponding countermeasures should be formulated we should take effective measures.
