The invention relates to a tensile force compensation washer, which comprises a flake-like substrate (10) of which the middle is provided with a through hole (11), wherein the substrate is provided with an inner segment (12) and an outer segment (13), the inner segment (12) and the outer segment (13) are distributed from inside to outside, and the inner segment and the outer segment are connectedthrough an inclination segment; and when the substrate is configured to exceed a preset temperature, the inner segment and the outer segment independently generate acting force to the outer side of the substrate for the normal direction of the substrate. The tensile force compensation washer has the beneficial effects that a tensile force compensation device is added between the upper end nut andthe fastening surface of a pull rod, at different temperatures, different forces are applied to the pull rod through the nut, so that the tensile force of the pull rod for a lower wiring device is kept, and the wiring device and an electric conduction pipe are guaranteed to be in normal contact; and under different load conditions, the device for keeping the tensile force of the pull rod is favorable for reducing the discharge faults of a high-capacity high-level transformer casing pipes.
