Detailed Description

In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system configurations, techniques, etc. in order to provide a thorough understanding of the embodiments of the present application. However, it will be apparent to one skilled in the art that the present application may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present application with unnecessary detail.

It should be understood that the terms "comprises" and/or "comprising," when used in this specification and the appended claims, specify the presence of stated features, integers, steps, operations, elements, and/or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and/or groups thereof.

For the sake of simplicity of the drawing, the parts relevant to the present utility model are shown only schematically in the figures, which do not represent the actual structure thereof as a product. Additionally, in order to simplify the drawing for ease of understanding, components having the same structure or function in some of the drawings are shown schematically with only one of them, or only one of them is labeled. Herein, "a" means not only "only this one" but also "more than one" case.

It should be further understood that the term "and/or" as used in this specification and the appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes such combinations.

In the embodiment shown in the drawings, indications of orientation (such as up, down, left, right, front and rear) are used to explain the structure and movement of the various components of the utility model are not absolute but relative. These descriptions are appropriate when the components are in the positions shown in the drawings. If the description of the location of these components changes, then the indication of these directions changes accordingly.

In addition, in the description of the present application, the terms "first," "second," and the like are used merely to distinguish between descriptions and are not to be construed as indicating or implying relative importance.

In order to more clearly illustrate the embodiments of the present utility model or the technical solutions in the prior art, the following description will explain the specific embodiments of the present utility model with reference to the accompanying drawings. It is evident that the drawings in the following description are only examples of the utility model, from which other drawings and other embodiments can be obtained by a person skilled in the art without inventive effort.

Referring to fig. 1, a strong torsion cable is disclosed, comprising a wire 10, an FEP sheath 20 and a strong wire 30, wherein: the strong filaments are not limited to 200D ballistic filaments. In the example, the bulletproof yarn is mainly made of polyaryl fiber, has high tensile strength, high hygroscopicity (no moisture absorption), stable size, good heat resistance, wear resistance, cutting resistance, acid resistance, impact resistance and excellent flame resistance, and is widely used for optical fiber cables and filling and reinforcing wires and cables; the conducting wires are a plurality of metal wires and are wrapped around the strong wires by taking the strong wires as the centers. In the example, the wire is a tinned copper wire, which uses 30 copper wires to twist the strength wire around the center. In an example, tinning with copper wire can prevent the insulation from sticking, blacking the core, embrittling, and improving its solderability. Can prevent oxidation-reduction reaction from generating, generate copper green, increase heat dissipation, improve conductivity and improve wire performance. Tinned copper wire, mainly used for rubber insulated mining cable, flexible wire, flexible cable, marine cable, etc., as conductive wire core, and used as outer shielding braid and brush wire of cable; FEP skin 20 is formed by heat curing in an extruder (or extruder), and FEP is formed by copolymerizing tetrafluoroethylene and hexafluoropropylene (commonly referred to as "plastic material"). In forming the cable, the wire is passed through an extruder and the wire is then coated with a plastic material by passing through the extruder.

In the foregoing embodiments, the descriptions of the embodiments are focused on, and the parts of a certain embodiment that are not described or depicted in detail may be referred to in the related descriptions of other embodiments.

It should be noted that the above embodiments can be freely combined as needed.
