The invention discloses a mineral insulated fire control cable which comprises three round copper conductors; the outer surfaces of the round copper conductors are coated with insulation layers so asto form power conductor cores; three power conductor cores are stranded to form a cable core; an alkali-free glass fiber band is wrapped on the outer surfaces of the three power conductor cores to form a band wrapped layer; the outer surface of the band wrapped layer is coated with a shielding layer; an oxygen barrier layer is coated on the outer surface of the shielding layer; the outer surface of the oxygen barrier layer is coated with an armor layer; the outer surface of the armor layer is coated with a low-smoke fire-retardant polyolefin jacket layer; a plurality of alkali-free glass fiberfilling ropes are filled between the band wrapped layer and the cable core; and the oxygen barrier layer and the insulation layer consist of the following components in parts by weight: an ethylene-octene copolymer, ore magnesium hydroxide, zinc borate, a lubricant, a diphenylamine anti-aging agent KY405 and porcelain powder. The mineral insulated fire control cable takes good fire-retardant, fire-proof, fire-insulated, waterproof and anti-seismic effects at a high temperature; softness of the cable is ensured; and when the environment around the control cable is on a fire, hard ceramic can be formed to prevent fire so as to avoid firing of internal materials.
