This application relates to a cable and its manufacturing method. The cable includes a cable body and an anchor. The cable body includes an inner wire layer and an outer wire layer, and is divided into a main body section and an anchoring section. The outer wire layer of the anchoring section is shorter than the inner wire layer. The first end of the anchor has a cable passage hole, and the second end of the anchor has a connection hole. The main body section of the cable body is located outside the anchor, and the anchoring section is located inside the connection hole. The space between the anchoring section and the connection hole is filled with filler. By making the outer wire layer of the anchoring section shorter than the inner wire layer, the cable of this application can achieve a lower holding force after anchoring compared to the inner wire layer.

3. The method according to claim 1, wherein the connection hole (220) comprises a first hole section (221), a taper hole section (222) and a second hole section (223) which are sequentially connected, the first hole section (221) is communicated with the cable passing hole (210), the diameter of the first hole section (221) is equal to the maximum diameter of the taper hole section (222), the diameter of the second hole section (223) is equal to the minimum diameter of the taper hole section (222), the anchor section (10 b) is located in the taper hole section (222), and the filler (30) is filled in a space between the anchor section (10 b) and the taper hole section (222).
4. A method of making a cable according to any of claims 1 to 3, wherein the cable through hole (210) and the connecting hole (220) each extend in the axial direction of the anchor (20).
5. The method of manufacturing a cable according to claim 1, wherein an inner wall of the cable hole (210) is formed with an internal thread (211).
6. The method of producing a guy cable according to claim 1, wherein the length of the outer wire layer (120) of the anchor section (10 b) is 0.5-1 times the diameter of the main section (10 a) of the cable body (10), and the length of the inner wire layer (110) of the anchor section (10 b) is 3-5 times the diameter of the main section (10 a) of the cable body (10).
7. The method of manufacturing a guy cable according to claim 1, wherein the center of the cable body (10) is arranged coaxially with the center of the anchor (20).
8. The method of manufacturing a pull cable according to claim 1, wherein the inner wire layer (110) comprises a plurality of alloy wires or stainless steel wires, and the outer wire layer (120) comprises a plurality of stainless steel wires, copper wires or aluminum wires.
9. The method for manufacturing the inhaul cable according to claim 1, wherein the cable body (10) is a steel stranded cable body (10), a steel wire rope body (10) or a sealing cable body (10), and the filler (30) is a hot-cast alloy or a cold-cast material.
