[0019] The inner side of the outer protective layer 1 is provided with a waterproof layer 13, which is made of a polyethylene layer.
[0020] The inner side of the waterproof layer 13 is provided with a halogen-free low-smoke layer 2, which is provided with a halogen-free low-smoke oxygen barrier layer 21, and the halogen-free low-smoke oxygen barrier layer 21 is provided with a fire-resistant sleeve 3. The halogen-free low-smoke layer 2 and the fire-resistant sleeve 3 have a gap, and the halogen-free low-smoke oxygen barrier layer 21 is filled between the halogen-free low-smoke layer 2 and the fire-resistant sleeve 3. The halogen-free low-smoke oxygen barrier layer 21 is also filled in the gap between the halogen-free low-smoke layer 2 and the fire-resistant sleeve 3. When the cable encounters external flame, the flame burns the halogen-free low-smoke layer 2, and no toxic gas is generated during the burning process. The halogen-free low-smoke layer 2 has strong flame retardant performance, and after leaving the fire source, the halogen-free low-smoke oxygen barrier layer 21 can extinguish the flame to a certain extent.
[0021] The inner side of the fire-resistant sleeve 3 is provided with a separation layer 31, and the separation layer 31 is provided with a filling layer 32. The filling layer 32 is provided with a conductor 4, which includes an inner protective layer 41. The inner side of the inner protective layer 41 is provided with a tensile layer 42, and the inner side of the tensile layer 42 is provided with a shielding layer 43. The shielding layer 43 is provided with a wire core 44. The inner protective layer 41 can further protect the wire core 44 inside the conductor 4. The tensile layer 42 is an aramid tensile layer.

[0022] In the above scheme, the filling layer 32 is a fiber filling and fixing layer. When the cable is subjected to mechanical external forces such as extrusion, bending and stretching, the fiber filling layer can act as a buffer medium. For example, when the cable is accidentally stepped on, extruded, or encounters a relatively narrow pipe corner during laying, the fiber can disperse stress, prevent the cable core from being directly stressed and cause problems such as insulation layer damage and wire core 44 deformation, maintain the integrity of the cable structure, and ensure stable electrical performance.
