Description

Technical Field

[0001] The utility model belongs to the technical field of power lines, and in particular relates to a novel high-voltage-resistant power line. Background Art

[0002] At present, there are many types of wires, including power cords, cable cords, signal cords, etc. Take the currently more commonly used power cord as an example. The power cord includes an inner core wire and an outer protective layer. However, the existing technology has a strict limit on the overall length of the power cord. If the power cord is too long, it is easy to cause the power cord to get tangled together. If the power cord is too short, it may cause the connection to fail, and then the power cord cannot be adjusted according to on-site demand.

[0003] Application number "CN202121850196.5" records "a voltage-resistant power cord, comprising an inner core, a plurality of circumferentially arranged outer cores are evenly arranged on the outer side of the inner core, a uniform stress-bearing layer is arranged on the outer side of the plurality of outer cores away from the inner core, the uniform stress-bearing layer is connected to the inner core through an elastic telescopic mechanism, an outer layer is installed outside the plurality of uniform stress-bearing layers, two first elastic pulling layers are installed on the side of any one of the outer cores, any one of the outer cores is connected to the inner core through a second elastic pulling layer, the two first elastic pulling layers are symmetrically arranged based on the second elastic pulling layer, and the ends of the two first elastic pulling layers away from the outer core are respectively installed on the two elastic telescopic mechanisms."

[0004] The above patent is based on a voltage-resistant power line. By setting a uniform stress layer, a single stress point can be converted into a total stress point, avoiding direct damage caused by excessive stress at a certain point. By setting a first elastic pulling layer and a second elastic pulling layer, when the uniform stress layer moves under stress, the lengths of the two first elastic pulling layers close to it are shortened, thereby reducing the pulling force, and the pressure of the two first elastic pulling layers and the two second elastic pulling layers away from the connecting layer is reduced accordingly, thereby pulling away the outer cores on both sides of the connecting layer to avoid being squeezed by the uniform stress layer, thereby improving the pressure resistance and further protecting the outer cores.

[0005] The above patent can convert single-point stress into total stress by setting a uniform stress layer, avoiding direct damage caused by excessive stress at a certain point. By setting the first elastic pulling layer and the second elastic pulling layer, when the uniform stress layer moves under stress, the lengths of the two first elastic pulling layers close to it are shortened, thereby reducing the pulling force, and the pressure of the two first elastic pulling layers and the two second elastic pulling layers far away from the connecting layer is correspondingly reduced, thereby pulling away the outer cores on both sides of the connecting layer to avoid being squeezed by the uniform stress layer, thereby improving the pressure resistance and further protecting the outer cores. However, the overall length limit of the above power cord is relatively rigid, resulting in the inability to adjust the power cord according to the required length on site, because if the power cord is too long as a whole, it is easy to cause the power cord to be knotted together, and if the power cord is too short, it may not be connected, resulting in greater overall limitations of the power cord.
