Summary:The invention relates to an isolated flexible mineral insulating fireproof single-core cable comprising a metal conductor, wherein the metal conductor is wrapped in a composite insulating layer; a metal tube is seamlessly extruded outside the composite insulating layer; a first isolating sleeve is disposed outside the metal tube; a first fireproof layer is formed outside the first insulating sleeve; a first wrapping layer is formed outside the first fireproof layer; a second isolating sleeve is formed outside the first wrapping layer; a second fireproof layer is formed outside the second isolation sleeve; a second wrapping layer is formed outside the second fireproof layer; a sheath is formed outside the second wrapping layer. The isolated flexible mineral insulating fireproof cable can bea single core cable and a multi-core cable. Compared with the prior art, the isolated flexible mineral insulated cable of the invention is not short-circuited under the flame, the internal temperature rise of the cable does
