This utility model provides a cable fixing structure for the handover test of a photovoltaic power station transformer substation, belonging to the technical field of cable fixing structures. The cable fixing structure includes: a wedge-shaped metal ring assembly divided into at least three circumferential segments, each segment having a spiral groove on its outer surface; a high-friction flexible pad tightly fitted to the inner circumferential surface of each segment; and an integral elastic steel ring surrounding the outer side of the metal ring assembly, the inner circumferential surface of which has a protruding ridge that engages with the spiral groove. When the elastic steel ring rotates relative to the metal ring assembly, the protruding ridge slides along the spiral groove, driving each wedge-shaped metal ring segment to synchronously contract radially and synchronously generate axial displacement, thus forming a self-tensioning clamp. This solves the problem of loose cable joints and uneven stress during the handover test caused by the inability of traditional fixing structures to adaptively clamp according to changes in cable tension.
