It is a special cable manufactured using a production process similar to that of cross-linked cables. It is a new power transmission method between overhead conductors and underground cables. Overhead cables are all single-core and can be divided into hard aluminum wire structures, hard-drawn copper wire structures, aluminum alloy wire structures, steel core or aluminum alloy core support structures, and self-supporting three-core stranded structures (the wire cores can be hard aluminum or hard copper wires) according to their different structures. It has the main characteristics of high power supply reliability, good power supply safety, convenient erection and maintenance, and reasonable economy. Its main technical parameters include weather resistance, insulation level, inner and outer semi-conductive shielding layers.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A parallel bundled overhead cable with enhanced tensile strength, including:

[0007] A cable for transmitting electric energy;

[0008] The number of the cables is five groups. On one adjacent side of every two groups of the cables, there are raised strips. On one adjacent side of the adjacent raised strips of every two groups, a plurality of magnetic blocks are evenly embedded. On one adjacent side of the adjacent raised strips of every two groups, there is a tearing line. On one side of the top and bottom of the adjacent raised strips close to the tearing line, there are inclined surfaces, and the cutting surfaces of every two groups of the inclined surfaces form a V-shaped structure. On one adjacent side of the adjacent raised strips of every two groups, a plurality of iron blocks are evenly embedded.

[0009] As a further scheme of the utility model: Each of the five groups of the cables includes a plurality of conducting cores. On the outer sides of the plurality of conducting cores, there are filling layers, and on the outer sides of the filling layers, there are insulating layers wrapped.

[0010] As a further scheme of the utility model: The magnetic blocks and the iron blocks are arranged alternately, and every two adjacent groups of the cables are magnetically connected through the mutual cooperation of the magnetic blocks and the iron blocks.

[0012] As a further scheme of the utility model: The plurality of magnetic blocks and the iron blocks are arranged in stages.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] Through the arranged cables, raised strips, magnetic blocks and iron blocks, during use, the connection ends of two groups of cables can be torn along the position of the tearing line on the adjacent two groups of raised strips, which is convenient for separately operating the end faces of each cable, including wiring operation. After the operation is completed, the adjacent two groups of cables can be contacted by using the magnetic blocks and the iron blocks, and the two groups of cables are adsorbed together by the magnetic attraction generated between the magnetic blocks and the iron blocks.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations. The following will describe the embodiments according to the overall structure of the present utility model.

[0021] Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a parallel bundled and tensile-strengthened overhead cable includes:

[0022] Cable 1 for transmitting electric energy;

[0023] The number of cables 1 is five groups. On the adjacent sides of each two groups of cables 1, there are raised strips 2. On the adjacent sides of each two adjacent groups of raised strips 2, multiple groups of magnetic blocks 3 are evenly embedded. On the adjacent sides of each two adjacent groups of raised strips 2, there is a tearing line. On the top and bottom of each two adjacent groups of raised strips 2, on the side close to the tearing line, there are inclined surfaces, and the cutting surfaces of each two inclined surfaces form a V-shaped structure. On the adjacent sides of each two adjacent groups of raised strips 2, multiple groups of iron blocks are evenly embedded. The thickness of the position at the tearing line is made thinner by using each two inclined surfaces with a V-shaped structure, which is convenient for tearing and reduces the difficulty of tearing.

[0024] Please refer specifically to Figure 1 , 2As shown in FIGS. 1 and 3, each of the five groups of cables 1 includes multiple groups of conducting cores 101. A filling layer 102 is provided on the outer side of each group of conducting cores 101, and an insulating layer 103 is wrapped around the outer side of the filling layer 102.

[0025] Please refer specifically to Figure 1 、 2 and 3, the magnetic blocks 3 and iron blocks 4 are arranged alternately. Adjacent two groups of cables 1 are magnetically attracted and connected through the mutual cooperation of the magnetic blocks 3 and the iron blocks 4. When the adjacent two groups of cables 1 are torn apart from the tearing line position, the magnetic attraction force between the magnetic blocks 3 and the iron blocks 4 can directly make the adjacent two groups of cables 1 adsorb together, avoiding the phenomenon that the cables 1 become messy due to entanglement.

[0026] Please refer specifically to Figure 1 、 2 and 3, adjacent two groups of cables 1 are fixedly connected through the raised strips 2 and the tearing lines.

[0027] Please refer specifically to Figure 1 、 2 and 3, multiple groups of magnetic blocks 3 and iron blocks 4 are arranged in a stepped manner. The stepped arrangement of the magnetic blocks 3 and the iron blocks 4 ensures that the raised strips 2 can bend by themselves without being affected by the magnetic blocks 3 and the iron blocks 4, ensuring the normal coiling and use of the cables 1.

[0028] The working principle of the present utility model is as follows: During use, the connection ends of the two groups of cables 1 can be torn apart along the tearing line position on the adjacent two groups of raised strips 2, facilitating separate operations on the end faces of each cable 1, including wiring operations. After the operations are completed, the adjacent two groups of cables 1 can be brought into contact by using the magnetic blocks 3 and the iron blocks 4, and the two groups of cables 1 are adsorbed together by the magnetic attraction force generated between the magnetic blocks 3 and the iron blocks 4. Thus, it can be ensured that the multiple groups of parallel bundled cables 1 during use will not be entangled and always remain in a parallel state, avoiding the phenomenon of looseness or entanglement between the multiple groups of cables, thereby making the use effect better when used in combination and improving the utilization rate to a certain extent.

[0029] The above-mentioned is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present utility model.
