Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a low-voltage tensile and wear-resistant reel cable. Background Art

[0002] Cables are usually rope-like cables made of several or several groups of wires (at least two in each group). Each group of wires is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering. Cables have the characteristics of being energized inside and insulated outside. With the development of society, there are many types of cables, such as power cables, control cables, compensation cables, shielded cables, high-temperature cables, computer cables, signal cables, coaxial cables, fire-resistant cables, marine cables, mining cables, aluminum alloy cables, etc.

[0003] At present, during the cable installation process, the cables will be subjected to strong pulling and twisting forces when the workers drag the cables. The cables may be broken during the strong pulling process, which will affect the use of the cables. In addition, when the cables are dragged, the cables will constantly rub against the ground, causing the outer surface of the cables to be easily worn, which will shorten the service life of the cables. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a low-voltage tensile and wear-resistant reel cable, which solves the problem that the cable may be broken when the worker drags the cable, thus affecting the use of the cable.

[0005] The utility model solves the above technical problems through the following technical means: a low-voltage tensile and wear-resistant reel cable, comprising a main core conductor, a control core conductor, a tensile layer and a wear-resistant layer, wherein there are three main core conductors, the three main core conductors are in a herringbone structure, and the control core conductor is arranged between the three main core conductors, the main core conductor and the control core conductor are coaxially sleeved with an insulating layer, a filling layer is arranged between the main core conductor and the control core conductor, an inner sheath is arranged between the wear-resistant layer and the insulating layer, the tensile layer is arranged between the inner sheath and the wear-resistant layer, and the tensile layer is fixedly installed on the surface of the inner sheath away from the insulating layer, and the tensile layer is a mesh structure.

[0006] Furthermore, it also includes three ground wires, which are in a herringbone shape and are cross-arranged with the three main line core conductors. The three ground wires are all covered with a coating layer, and the coating layer is against the inner protective layer.

[0007] Furthermore, it also includes a shielding component, which is arranged between the tensile layer and the wear-resistant layer, and is used to prevent the cables from interfering with each other.

[0008] Furthermore, the shielding assembly includes a first shielding layer and a second shielding layer, the first shielding layer is coaxially sleeved on the tensile layer, the second shielding layer is coaxially sleeved on the first shielding layer, and the second shielding layer is against the wear-resistant layer.

[0009] Furthermore, the second shielding layer is a corrugated copper tube.

[0010] Beneficial effects of the utility model:

[0011] 1. The tensile resistance of the cable can be improved by the anti-tensile layer of the mesh structure. The wear resistance of the cable can be improved by setting the wear-resistant layer. The coordination of the main core conductor and the control core conductor of the herringbone structure and the stability of the triangle can improve the bending resistance of the cable, thereby reducing the possibility of the cable being broken.

[0012] 2. The setting of the shielding layer can prevent the cables from interfering with each other.

[0013] 3. The setting of the corrugated copper tube improves the extensibility and resilience of the cable, further reducing the possibility of the cable being broken. BRIEF DESCRIPTION OF THE DRAWINGS
