The invention discloses a mineral ceramic fireproof high-temperature-resistant electric wire, which comprises an outer isolation combination layer and a core wire imbedding sheath layer arranged at the inner side of the outer isolation combination layer, and is characterized in that the outer isolation combination layer is composed of a whole-section coating layer, an anti-tear protection interlayer, an electric insulation protection interlayer and a plurality of middle segmented isolation layers; the folding buffer strips are V-shaped in structure, friction force between the layers on the two sides can be increased under the action of extrusion contact when the folding buffer strips are subjected to extrusion force, then excessive displacement of the core wires placed in the wrapping layer in the extrusion process due to the influence of the pressure is avoided, the stability of the position of the core wires placed in the wrapping layer is kept, and the service life of the core wires is prolonged.
