High-flame-retardant control cable with oxygen barrier layer

The utility model discloses a high-flame-retardant control cable with an oxygen barrier layer, which belongs to the technical field of control cables and comprises a wrapping layer. An oxygen barrier layer is arranged in the wrapping layer; an insulating layer is uniformly arranged in the oxygen barrier layer, and a conductor is arranged in the insulating layer; an inner flame-retardant layer is arranged outside the wrapping layer; the shielding layer is arranged outside the inner flame-retardant layer, and when internal spontaneous combustion occurs, the oxygen isolation layer made of oxygen isolation materials is arranged outside the insulating layer, so that a large amount of water can be separated out to lower the environment temperature during internal spontaneous combustion, and a non-melting and non-combustible aluminum oxide hard shell is formed to isolate contact with external air; and the cable is provided with the inner flame-retardant layer, so that the flame-retardant effect can be further improv
