description The invention relates to the field of cable manufacturing, in particular to an NW type combustion A-level mineral insulated cable, which comprises a wire core, an insulating layer, a shielding layer, a waterproof layer, a fireproof layer and a sheath, and is characterized in that the wire core comprises a copper conductor and is used for transmitting electric energy; the insulating layer comprises powdery magnesium oxide, the particle size of the powdery magnesium oxide is 0.5-1 [mu] m, and the sheath is a copper sheath; the wire core, the insulating layer, the shielding layer, the waterproof layer, the fireproof layer and the sheath are sequentially wrapped from inside to outside; the outer diameter of the cable is greater than 20mm; the surface of the copper sheath is of a latticed structure, and the surface of the copper sheath is coated with an insect-resist agent. The scheme also comprises a method for detecting whether the cable is qualified, the to-be-detected cable is divided into the first cable samp
