High-flame-retardant control cable

The utility model relates to the technical field of cables, in particular to a high-flame-retardant control cable, which is characterized in that the cable extends into a sleeve through a first mounting port at the bottom end of the sleeve, is limited through a plurality of groups of clamping plates, and extends out through a second mounting port at the bottom end of the sleeve. A carbon dioxide generator is turned on to discharge carbon dioxide into the casing pipe through the first detection box, meanwhile, a first electromagnetic valve is turned on to enable the carbon dioxide to flow from left to right and enter the second detection box, when the gas detector detects that the carbon dioxide in the second detection box is sufficient, the first electromagnetic valve is turned off, and after the gas pressure reaches the standard, the first electromagnetic valve is turned on; when the cable is short-circuited, the carbon dioxide generator stops exhausting, and when the cable is short-circuited, generation of
