The invention discloses a luminous intrinsic safety four-core composite low-voltage cable for an environment-friendly intelligent power grid and a fabrication method of the cable. The cable comprises a cable core, wherein the cable core is formed by twisting a single round insulation wire core and a plurality of fan-shaped insulation wire cores, a gap of the cable core is filled with a halogen-free low smoke glass fiber rope, a ceramic fireproof layer wraps the cable core, a metal armor layer wraps the ceramic fireproof layer, a high-conduction alloy wire is embedded in the metal armor layer, a high-strength halogen-free low smoke flame-retardant olefin outer protection layer is extruded outside, a fluorescent sensing red warning color tape is arranged in the high-strength halogen-free low smoke flame-retardant olefin outer protection layer, the round insulation wire core comprises a round conductor and a round insulation layer, the round insulation layer wraps the round conductor, each fan-shaped insulation wire core comprises a fan-shaped conductor and a fan-shaped insulation layer, and the fan-shaped insulation layer wraps the fan-shaped conductor. With the adoption of a structure combining a round shape and a fan shape, the roundness and all performances of the cable are further improved; and the cable is reasonable in structure design, the backward yield is eliminated, the transformation of scientific and technological achievements is achieved, the product cost performance is greatly improved, the resource is saved, and the benefit is brought to people.
