Flame-retardant fireproof aluminum alloy photovoltaic cable

The invention relates to the technical field of cables, and particularly discloses a flame-retardant fireproof aluminum alloy photovoltaic cable, which comprises wire cores and an inner framework, a plurality of wire cores are inserted into mounting grooves in the inner framework, the outer side of the inner framework is wrapped with a flame-retardant sleeve, the flame-retardant sleeve is filled with a flame retardant, the outer side of the flame-retardant sleeve is provided with an outer framework, and the outer side of the outer framework is wrapped with a sheath. The outer framework is installed on the outer side of the flame-retardant sleeve and has certain elasticity, when the outer skin is extruded, force is applied to the outer framework through the outer skin, the buffering and force unloading effects on the internal structure are achieved, the internal flame-retardant sleeve can be protected, and the situation that the flame-retardant sleeve is broken due to extrusion is avoided; the cutting knife is
