High-fire-resistant power cable

The invention relates to a high-fire-resistant power cable which comprises a cable core and a protective sheath coated outside the cable core, wherein the protective sheath is a low-smoke halogen-free sheath; a first weaving layer and a first fire-resistant mica tape are sequentially arranged between the protective sheath and the cable core from outside to inside; the cable core is a conductor formed by winding a plurality of electrical units; and the electrical units sequentially comprise second weaving layers, second fire-resistant mica tapes and metal bare wires from outside to inside. The cable is in a double fire-resistant mica tape and double glass fiber weaving layer structure, so that the cable has double flame retardance, better fire resistance and corrosion resistance, and excellent tensile resistance and compression resistance, and the service life of the cable is prolonged.
