The invention provides a power cable information identification two-dimensional code label mounting device. The device comprises a mounting base of a cuboid structure and a fixing part used for fixingthe mounting base, the upper surface of the mounting base sinks to form a mounting groove used for containing a two-dimensional code label, the mounting base is provided with a through hole which islocated below the mounting groove, the fixing part penetrates through the through hole and fixes the mounting base in a detachable mode; a papery two-dimensional code label can be well protected, thedamage caused by label abrasion and environment humidity to the label is prevented, data integrity of a power cable is ensured, and information reading is facilitated when workers conduct operation and maintenance; reutilization can be conducted, two-dimensional code label replacement is facilitated in the power cable information updating process, the use cost is greatly lowered, resources are saved, and environmental friendliness is facilitated.
