The invention discloses a self-ice-melting overhead insulated wire, comprising, from inside to outside, an optical fiber layer, a core layer, a semi-conductive layer and an outer insulating layer. The optical fiber layer comprises a hollow stainless steel tube and built-in optical fibers; a steel tube insulating layer is extruded outside the stainless steel tube. A plurality of single-strand wire cores are stranded in layers in reverse directions outside the optical fiber layer, and heating wires are embedded in the outer insulating layer. The semi-conductive layer and the outer insulating layer are sequentially extruded outside the core layer. The invention also discloses a monitoring device, comprising a sensing optical fiber strain demodulator, a power supply device and a control switch. The sensing optical fiber strain demodulator is connected to the optical fibers and one end of the control switch, the other end of the control switch is connected to the power supply device, and the power supply device is connected to the heating wires. The invention has the beneficial effects that it can automatically melt ice and snow according to the stress and strain conditions of the insulated wire, without manual or unmanned aerial vehicle inspection of the entire line or manual electrification heating; it greatly improves the safety of the line under icing conditions and reduces line maintenance costs.
