[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] It should be noted that: the composite flame-retardant layer 4 gives the cable good flame retardancy, making it less likely to catch fire, thus increasing safety and reducing the probability of electrical accidents caused by flames; the waterproof layer 3 improves the waterproof effect inside the cable; the puncture-resistant layer 6 and the abrasion-resistant layer 7 make the cable more wear-resistant and durable; and the buffer strip 5 can cushion the cable when it is compressed, providing better protection for the internal cable core 1.

[0019] In a preferred embodiment, the composite flame retardant layer 4 includes a first glass fiber layer 401, a frame 402 disposed outside the first glass fiber layer 401, a second glass fiber layer 403 disposed outside the frame 402, and a flame retardant filler 404 filled inside the frame 402.

[0020] It should be noted that the frame 402 makes the cable structure more robust. The first glass fiber layer 401 and the second glass fiber layer 403 are respectively set inside and outside the frame 402 to achieve a double-layer effective flame retardant and high temperature resistance effect. The flame retardant filler 404 filled inside the frame 402 can further improve the flame retardant ability of the cable.

[0021] In a preferred embodiment, the frame 402 includes a plurality of equally spaced annular rings 402-1 and a plurality of equally spaced connections 402-2 connected to the outer wall of the annular rings 402-1.

[0022] It should be noted here that the ring 402-1 and the connecting strip 402-2 are combined to form a frame 402 that covers the outside of the cable core 1.

[0023] In a preferred embodiment, the wear-resistant layer 7 is a nitrile rubber layer, and the puncture-resistant layer 6 is a nylon layer.

[0024] It should be noted that the nitrile rubber layer has good abrasion resistance, and the nylon layer has good puncture resistance.

[0025] In a preferred embodiment, a gap is left between the composite flame-retardant layer 4 and the puncture-resistant layer 6.

[0026] It should be noted that when the cable is under pressure, the composite flame-retardant layer 4 and the puncture-resistant layer 6 come together and squeeze the buffer strip 5, which can play a buffering role.

[0027] Working principle: The frame 402 makes the cable structure more robust. The first glass fiber layer 401 and the second glass fiber layer 403 are set inside and outside the frame 402 respectively, which can achieve a double-layer effective flame retardant and high temperature resistance effect. The flame retardant filler 404 filled in the frame 402 can further improve the flame retardant ability of the cable, making the cable less likely to catch fire, making it safer and reducing the probability of electrical accidents caused by flames. The waterproof layer 3 can improve the waterproof effect inside the cable. The puncture-resistant layer 6 and the wear-resistant layer 7 make the cable more wear-resistant and durable. The buffer strip 5 can play a buffering role when the cable is compressed, which can better protect the internal cable core 1.
