[0005] The core wire is formed by twisting a plurality of metal fibers, the diameter of the metal fiber is 0.15-0.22mm, and the number of the metal fiber is 60-99.

[0006] The reinforcing layer is formed by winding nylon mesh cloth.

[0007] The buffer layer is made of polyurethane corrugated tape and natural rubber, and the thickness of the buffer layer is 1-3mm.

[0008] The intermediate reinforcing wire is composed of more than 4 metal fibers, which are arranged in a spiral shape on the surface of the intermediate layer, the diameter of the metal fiber is 0.5-2mm, and the number is 4-20.

[0009] The intermediate layer is covered with carbon fiber mesh.

[0010] The mixed layer is made of corrosion-resistant material.

[0011] The utility model discloses after adopting above -mentioned scheme, the core line surface through carbon fiber mesh piece cladding again soaks mixed layer, effectively increased the wear resistance and impact resistance of core line, adopts the middle reinforcing thread winding can effectively increase the tensile property and impact resistance, adopts the buffer layer to protect the center wire, simultaneously fills the gap between center wire and mixed layer, makes center wire and mixed layer form an integrity, finally again through nylon mesh cloth winding cladding forms the strengthening layer, and the strengthening layer soaks the anticorrosive solution and forms the surface layer, thereby the core line has strong corrosion resistance and tensile property, and the impact cable after adopting this scheme has big tensile strength, good corrosion resistance and strong impact resistance.

[0017] The impact-resistant cable for test comprises a core wire 1, an intermediate reinforcing wire 2 and a reinforcing layer 3. The core wire 1 is formed by twisting a plurality of metal fibers, the diameter of the metal fiber is 0.15-0.22mm, and the number of the metal fibers is 60-99. The core wire 1 is coated with an intermediate layer 4 formed by a carbon fiber mesh. The intermediate layer 4 is coated with a mixed layer 7 made of corrosion-resistant material. The mixed layer 7 is spirally wound with the intermediate reinforcing wire 2 on the outside. The intermediate reinforcing wire 2 is composed of more than 4 metal fibers, which are spirally arranged on the surface of the intermediate layer 4. The diameter of the metal fiber is 0.5-2mm, and the number of the metal fibers is 4-20. The intermediate reinforcing wire 2 is coated with a buffer layer 5 made of polyurethane corrugated tape and natural rubber, and the thickness of the buffer layer is 1-3mm. The buffer layer 5 is provided with the reinforcing layer 3 formed by winding nylon mesh cloth. The reinforcing layer 3 is provided with a surface layer 6 made of corrosion-resistant material.
