Earthquake -proof cable

The utility model discloses an earthquake -proof cable, this cable set up double -deck buffer structure between armor and insulating layer. First buffer layer has the honeycomb cavity, and its radial deformability is excellent, when the cable receives vibrations, is absorbed by first buffer layer to the vibration energy of cable inside transmission is most by the armor, the second buffer layer is inside to set up the air chamber, makes it have good pliability and deformability, fails will be absorbed by the second buffer layer by the absorptive vibration energy of first buffer layer. Like this, finally transmit the vibration energy who locates to the insulating layer and the cable core of cable has just been weakened by a wide margin. Had duplicate protection, inside insulating layer of cable and cable core just are difficult to impairedly, and this cable has good anti -seismic performance. 本实用新型公开了种抗震电缆，该电缆在铠装层与绝缘层之间设置双层的缓冲结构。第缓冲层有蜂窝状的空腔，其径向的形变能力优异，当电缆受到震动时，由铠装层向电缆内部传递的震动能量大部分被第缓冲层吸收；第二缓冲层内部设置气室，使其具有优良的柔韧性和形
