According to the size of a 110 kV substation distribution equipment outlet, put forward a double outlet scheme different from conventional outlet. In the configuration of double outlet and terminal tower, presented two schemes. Scheme one applied two double loop tower outlet arrangement scheme; Scheme two applied a four loop tower outlet arrangement scheme. The research results show that: 1）Under the condition of meeting the charged distance in the outlet scheme, the double outlet scheme greatly reduces the floor space area comparing with conventional outlet, and reduces the length of the main bus; 2）For different outlet corridors of Scheme one and Scheme two, each has advantages and can be selected on the basis of actual situation.
