[0003] In the existing cable technology, some problems often occur during the installation and use of stranded wires. When installing traditional cables, usually one place is fixed first and then the next place is fixed. Usually, the cable needs to be pulled. Due to the high self-weight of the cable, during this process, the stranded wire is prone to slipping inside the cable sleeve, which may lead to unstable connection of the cable, affect the electrical performance, and even cause potential safety hazards. In addition, when the cable is laid in the wild, it is prone to be damaged by spiky objects during installation, which may cause damage to the cable and affect its normal use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The present utility model will be further described below with reference to the drawings and embodiments.

[0021] Please refer to Figure 1 , Figure 2 ,Figure 3 , Figure 4 and Figure 5 , where Figure 1 is a schematic structural view of a preferred embodiment of a self-supporting heavy-duty heat-resistant and corrosion-resistant stranded wire provided by the present utility model; Figure 2 is Figure 1 a cross-sectional schematic view of the cable shown; Figure 3 is Figure 1 a schematic structural view of the mounting ring shown; Figure 4 is Figure 2 a schematic structural view of the energy-absorbing layer shown; Figure 5 is Figure 3 a schematic structural view of the inner core tightening plate shown. A self-supporting heavy-duty heat-resistant and corrosion-resistant stranded wire includes: a cable 1, an installation ring 2 is arranged inside the cable 1, two installation ears 3 are fixedly connected to the installation ring 2, an installation groove 4 is formed in the installation ear 3, a sliding block 6 is slidably connected inside the installation ear 3, a guide groove 7 is formed in the sliding block 6, an inner core tightening plate 5 is fixedly connected to one side of the sliding block 6, a spring 8 is fixedly connected to the other side of the sliding block 6, an energy-absorbing layer 9 is arranged inside the cable 1, a plurality of energy-absorbing holes 10 are formed on the surface of the energy-absorbing layer 9, a plurality of fixing blocks 11 are fixedly connected to the energy-absorbing layer 9, a buffer layer 12 is arranged inside the cable 1, and the outer layer of the stranded wire is made of a heat-resistant and corrosion-resistant material, so that it can still maintain good performance in a harsh environment, improving the reliability and safety of the cable.

[0022] The material of the buffer layer 12 is silicone, and the material of the energy-absorbing layer 9 is steel. Silicone has good elasticity and buffering performance, and can effectively reduce vibration and impact.

[0023] An outer skin 13 is arranged on the surface of the cable 1, an anti-corrosion layer 14 is arranged on the surface of the outer skin 13, and a heat-resistant layer 15 is arranged on the inner surface of the outer skin 13. The anti-corrosion layer 14 and the heat-resistant layer 15 can improve the anti-corrosion property and heat resistance of the cable 1.

[0024] The material of the anti-corrosion layer 14 is polyvinyl chloride, and the material of the heat-resistant layer 15 is polytetrafluoroethylene. Polyvinyl chloride and polytetrafluoroethylene have remarkable anti-corrosion performance and heat resistance.

[0025] An inner core protection layer 16 is arranged inside the cable 1, a load-bearing layer 17 is arranged inside the inner core protection layer 16, a stranded wire 18 is arranged inside the inner core protection layer 16, and an inner core 19 is arranged inside the inner core protection layer 16. The load-bearing layer 17 can improve the self-load-bearing performance of the cable 1, and the stranded wire 18 has good conductivity and anti-interference ability.

[0026] The material of the inner core protective layer 16 is rubber, and the material of the load-bearing layer 17 is steel wire. The inner core protective layer 16 provides secondary protection for the cable 1 and improves the safety performance of the inner core 19.

[0027] The working principle of a self-supporting heavy-duty heat-resistant and anti-corrosion stranded wire provided by the present utility model is as follows:

[0028] When installing the cable 1, it is necessary to pull the cable 1 for fixation. When making a fixation at one place, pass the installation bolt through the installation slot 4 on the installation ear 3, and through the guide slot 7, make the sliding block 6 slide towards the inside of the cable 1, so that the inner core tightening plate 5 closely adheres to the stranded wire inside the cable 1. The two inner core tightening plates 5 form a restraint. When the construction personnel pull the cable, the stranded wire will no longer become loose or slip off from the cable outer skin due to its own weight. When the cable 1 needs to be laid in the wild, it is very likely to be damaged by spiky objects such as gravel. When some stones pierce into the cable 1, the energy-absorbing layer 9 will play a role. Since the fixing block 11 is higher than the energy-absorbing hole 10, the stones that pierce into the cable 1 will get stuck in the energy-absorbing hole 10, and the surrounding fixing blocks 11 will share the inward force of the gravel at the same time. At the same time, the buffer layer 12 plays a buffering role, so that the momentum of these spiky objects piercing inward is greatly resisted to protect the cable inner core.

[0029] Compared with the related technologies, a self-supporting heavy-duty heat-resistant and anti-corrosion stranded wire provided by the present utility model has the following beneficial effects:

[0030] This cable 1 has a special installation structure designed to keep the stranded wire stable inside the cable sleeve, avoid the occurrence of wire slipping, improve the connection stability and electrical performance of the cable, and an energy-absorbing layer 9 is provided to protect the cable. When the cable is damaged by spiky objects, the energy-absorbing layer 9 can absorb part of the energy, reduce the damage to the cable, and extend the service life of the cable.

[0031] The above are only the embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structure or equivalent process transformation made by using the specification and drawings of the present utility model, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present utility model by the same token.
