Abstract It is presented that，in the design of power transformation and distribution system for domestic civil aviation airports，the 35 kV central substation at the airport adopts three power supplies with line transformer unit；and the 10 kV uses the six segments new wiring scheme. Because of simplification of the wiring at 35 kV side，the relaying protection becomes simple；and the 10 kV side has multiple protection，so as to maximize the reliability of the power supply at civil aviation airports.
