The invention relates to an integrated bus bar and GIS equipment provided with the integrated bus bar. The integrated bus bar comprises a main bus bar with the axis of the main bus bar to extend along the anterio-posterior direction and used for the arrangement of a corresponding three-phase bus conductor. The bar wall of the main bus bar is integrally provided with three insulated switch shells that are arranged at intervals along the anterio-posterior direction. Each insulated switch shell is composed of a mechanism installation cylinder and an insulated spacer installation cylinder vertically arranged relative to the mechanism installation cylinder, wherein the axis of the mechanism installation cylinder is vertical to the anterio-posterior direction and the insulated spacer installation cylinder is used for the installation of a corresponding insulated spacer. According to the technical scheme of the invention, the problem in the prior art that a conventional bus bar and a conventional insulated switch shell are separately arranged to cause more product parts and non-compact structure can be solved.
