Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Refer to Fig. 1~3, in the utility model embodiment, a kind of excellent power cable of anti seismic efficiency, including outside armouring
Shell 1, cable core 7 and inner core 12；The inside of the armouring shell 1 is disposed with the first buffer layer 2 and second and subtracted from outside to inside
The material of shake layer 3, the first buffer layer 2 and the second buffer layer 3 is silicon rubber, to improve the damping effect of cable；Described second
The outside of buffer layer 3 is evenly arranged with some first projections 4, and the first projection 4 is close to the inner side of the first buffer layer 2, the second damping
The outside of layer 3 is also evenly arranged with some second projections 5, and the length of the second projection 5 is less than the first projection 4, and the He of the first projection 4
Second projection 5 is staggered, and the projection 5 of the first projection 4 and second is rubber shock-absorbing material, when cable is given a shock,
First projection 4 weakens shaking force, when the vibrations that cable is subject to are excessive, the interior side contacts of the second projection 5 and the first buffer layer 2,
Further weaken shaking force, to protect the inside of cable；Second buffer layer 3 is internally provided with inner core 12, inner core 12
Length is identical with cable length, and the section of inner core 12 is regular hexagon；It is installed with six sides of the inner core 12
