Abstract

PURPOSE:To simplify a testing method by utilizing the longitudinal rod structure of a connection part between the case of a gas insulation opening and closing device for an underground line and a pipe bus. CONSTITUTION:To a cable connector 3 having internal longitudinal rod constitution for a disconnection between a cable and a switching device, etc., a testing bushing 1 is connected through an adapter 2. Instead of the cable head of this adapter 2, a conductor 4 of the same size with the cable head is supported and fixed by an insulating spacer 5. Then, the upper lid 7 of a cable connecting container 6 is composed of an insulating rod 8 and an airtight structure 9, and the rod 8 which corresponds to every phase of the application of a voltage is inserted, so that the dielectric strength of a gas insulation opening and closing device for an underground line is tested easily.
