    Abstract: This paper introduced a general layout scheme of the gas-insulated transmission line (GIL) project of Nanyang station. It proposed the standardized unit design of the vital components of the project and studied the advantages and disadvantages of three sets of fault location systems with different principles.In addition, this research analyzed the plan which could shut down the reclosing of the opposite substation when the GIL fails, and the differential protection device employed the scheme of a special remote signal transmission device and channel. This paper elaborated on different maintenance plans for the bus air chamber fault and the existing problems of the flexible design part based on the starting point of dismantling the faulty unit, which is the nearest automatic balancing expansion joint or expansion hinge. It provides a reference for the follow-up 1 000 kV GIL projects from various aspects, such as machinery manufacturing, engineering design, operation, and maintenance, etc.
    Key words: UHV; gas-insulated transmission line(GIL); key component; fault location system; differential protection; maintenance plan
