Flame-retardant B1-level fire-resistant cable

The utility model relates to the technical field of wires and cables, in particular to a flame-retardant B1-level fire-resistant cable, which comprises a cable core with a circular cross section, wherein conductors which are twisted in pairs and a filling layer are fixed together by a wrapping tape; the shielding layer coats the outer wall of the cable core; the outer wall of the shielding layer is coated with the flame-retardant layer; and the outer sheath is extruded on the outer wall of the flame-retardant layer. According to the utility model, the flame-retardant layer formed by multiple layers of wrapping is arranged, the wrapping tape for wrapping uses the composite wrapping tape, the composite wrapping tape comprises the mica tape layer and the glass tape layer, both the mica tape layer and the glass tape layer have better heat-resistant and flame-retardant effects, and the glass tape-mica tape-glass tape-mica tape composite structure is formed by multiple layers of wrapping, so that the flame-retardan
