as shown in fig. 2 and 6, when the cable is impacted and pressed from the outside, the elastic sheet 17 elastically deforms and extrudes the air storage bag 20, at this time, under the elastic action of both the elastic sheet 17 and the air storage bag 20, the cable can be effectively cushioned and protected, the structure of the cable core 16 is prevented from being damaged, and when the cable encounters a fire, the air storage bag 20 is broken and inert gas in the air storage bag is sprayed out, so that the flame retardance and the fire prevention of the cable are realized;
as shown in fig. 1-4 and fig. 7, when the cable is broken, the fluid gelatin mixed with the iron powder in the filling layer 15 flows to the cable core 16 along the crack, and because the gelatin mixed with the iron powder presents conductivity, the filling layer 15, the cable core 16, the positive electrode guide piece 11, the negative electrode guide piece 12 and the alarm 9 form a passage, which is equivalent to connecting the alarm 9 in parallel with the outer side of the cable core 16, so that the alarm 9 can automatically alarm after the cable is broken, and meanwhile, the iron powder in the gelatin in the filling layer 15 at the broken part can be rapidly oxidized and discolored, thereby being convenient for a worker to rapidly check and repair the broken part, and completing a series of work.
What is not described in detail in this specification is prior art known to those skilled in the art.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
