To provide a bushing for an electrical device which is easy to install on an electrical device of the same rated voltage used for exchange and is economical and can fully respond to emergency exchange requirement.
The bushing 1 for an electrical device is mounted on the electrical device, while a central conductor 3 is arranged inside an insulator tube 2, and a head terminal 4 for connecting the central conductor 3 with a system wire is arranged on an upper end of the insulator tube 2 and a flange 5 is fixed on a lower end of the insulator tube. The central conductor 3 is constituted with a hollow fixed side conductor 3A connected with a head terminal 4 side on one end and preparing a conductor side connection terminal 7 at the other end, and a movable side conductor 3B slidably connected to and retained on the conductor side connection terminal 7 and connected to a device side connection terminal 8 at a free end. Contact frictional force of the conductor-side connection terminal 7 is set larger than the contact frictional force of the device side connection terminal 8.
