The invention discloses a sliding fitting for electric equipment. The sliding fitting comprises a bracket for connecting a pipe bus and a connecting plate for connecting electric equipment; landing legs are arranged at the lower end of the bracket, a supporting shaft is arranged in each landing leg, and the supporting shaft penetrates a supporting plate; the supporting plate is fixed on the connecting plate, a sliding slot is formed in the supporting plate, and the supporting shaft penetrates in the sliding slot and capable of sliding along the sliding slot, wherein the sliding slot is a circular arc. The sliding fitting can well displace and slide under the seismic effect so as to balance the height difference caused by equipment deformation in a loop system, thereby reducing the bad influence on the electric equipment by the seismic effect; the structure system of the electric equipment is protected, the safety running of a power grid system is maintained, and the anti-seismic property of the electric equipment is improved.
