[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Reference Figure 1-3 The utility model provides an embodiment: a steel belt longitudinally wrapped water-blocking and pressure-resistant cable, including a sheath 1, which can provide protection for the cable as a whole to prevent the cable from being damaged by wear and tear. The inner wall of the sheath 1 is provided with multiple staggered steel belts 2, which can improve the overall tensile and compressive strength of the cable, thereby protecting the internal structure from damage. The inner wall of the steel belt 2 is provided with a water-blocking tape 3, which can prevent moisture from entering the cable interior, thereby protecting the integrity of the cable structure. The inner wall of the water-blocking tape 3 is provided with a cable core filler 4, and the outer periphery of the middle end of the cable core filler 4 is provided with multiple fillings. Hole, by setting the filling hole into a triangle, the compressive resistance of the cable core filler 4 can be improved, and a plurality of steel wire fillers 6 are arranged in the filling hole. By setting a plurality of steel wire fillers 6, the compressive resistance of the entire cable can be further enhanced, and a plurality of loose tube sleeves 5 are arranged on the inner periphery of the cable core filler 4, and a plurality of core strengthening cores 10 are arranged in the center of the cable core filler 4. The core strengthening core 10 can improve the bending resistance of the cable, and a plurality of sleeve fillers 7 are arranged on the inner wall of the loose tube sleeve 5, and a plurality of conductors 8 are arranged inside the sleeve filler 7, and a core filler 9 is arranged in the center of the sleeve filler 7.

[0023] Reference Figure 1-3 , wherein the material of the sheath 1 is polyethylene, which has good corrosion resistance, wear resistance and aging resistance. The material of the water-blocking tape 3 is butyl rubber, which has very good air tightness and strong moisture barrier ability. The material of the cable core filler 4 is glass fiber, which has the characteristics of high temperature resistance and high strength. The material of the sleeve filler 7 is sealing putty, which is a sticky and plastic material. The material of the core filler 9 is polypropylene tear film, which has good insulation properties and can effectively prevent short circuits between the cores.
