The two-way sleeve comprises an inner-core conduction column and an insulating which is poured and wrapped on circumferential periphery of the inner-core conduction column. One end of the two-way sleeve is connected with an inlet/outlet wire and the other end is connected with a load switch or an isolation switch of a ring main unit. The earthing control module comprises an earthing static contact, an earthing chamber and an earthing conductive pole, wherein the earthing conductive pole can axially move and is connected with the earthing static contact in a plug-in manner. Natural air is taken as an insulating medium and a conventional solid-insulation pouring technology is combined, so that an earthing switch realized by the earthing control module and the sleeve connected with the inlet wire or the outlet wire are organically integrated into a pouring module. A discrete division problem is solved. A phase-to-phase isolation problem is also solved by transferring a high electric field to a solid insulating medium with an electric performance.
