Abstract

A gas-insulated metal enclosed switchgear including: a housing for housing a plurality of circuit equipments; at least three first insulating bushings penetrating through an outer wall of the housing; at least three second insulating bushings penetrating through an outer wall of the housing; and at least three cables positioned in parallel with each other adjacent to the outer wall of the housing, each connecting between one of the first insulating bushings and one of the second insulating bushings, respectively; in which; each of the first and second insulating bushings has a head with trapezoidal portions formed at both sides thereof and connected to one of the cable at at least one side of the trapezoidal portions for connecting the circuit equipments, respectively; a side face of a first side of the trapezoidal portions of a first-phase insulating bushing out of the first and second insulating bushings is set adjacent to a side face of a second side of the trapezoidal portions of a second-phase insulating bushing out of the first and second insulating bushings, respectively; and a side face of a first side of the trapezoidal portions of a second-phase insulating bushing out of the first and second insulating bushings is set adjacent to a side face of a first side of the trapezoidal portions of a third-phase insulating bushing of the first and second insulating bushings, respectively.
