PROBLEM TO BE SOLVED: To reduce a housing in size and weight and to make it inexpensive. SOLUTION: A switchgear comprises lower support glass 4 of each phase mounted on a fulcrum 20 of a floor 1 of the housing, a lower stud bolt 21 of which the lower end is engaged with the upper end of each lower support glass 4, a lower fixed electrode 6 of each phase inserted to the upper end of each lower stud bolt 21 and fixed thereto by nuts 23, 24; an upper stud bolt 25 of each phase of which the lower end is inserted to each fixed electrode 6 and fixed thereto by the nuts 23, 24, upper support glass 9 of each phase of which the lower end is engaged with the upper end of each stud bolt 25, an upper fixed electrode 10 of each phase mounted to the upper end of each upper support glass 9 and connecting bodies 28, a phase-to-phase insulating barrier 15 arranged between the adjacent electrodes 6, 10 and connected to the adjacent connecting bodies 28, a ground-to-ground insulating barrier 16 arranged between grounds of the fixed electrodes 6, 10 of phase at both ends, and connected to the other end of the connecting body 28 of which the one end is connected to the phase-to- phase barrier 15, and fixing bodies 18 for fixing the insulating barriers 15, 16 to the floor 1.
