摘要： PROBLEM TO BE SOLVED: To provide a switch gear which is downsized in overall shape by scaling down its mobile section, and to provide a method of sealing the switch gear. SOLUTION: The sectional form in the axial direction of the embedded metal of an insulating rod 4, which connects the current application shaft 5 on movable side of a switch with an operation mechanism while insulating them, is cross- shaped. Consequently, it becomes possible to suppress the field strength along the surface of the insulating rod 4 to a slight increase and reduce the field strength of the metallic part exposed in air of the current application shaft 5 on movable side by a large margin. Furthermore, it is possible to reduce the insulation distance in air and scale down the mobile part of the switch gear, since it is not affected by the stain or dampness along the surface of the insulator by charging the mobile part S with dry air or nitrogen gas and sealing it.
