Embodiment Construction

[0014] Such as figure 1 As shown, a kind of anti-seismic cable of the present invention includes the cable core that is stranded by several wire cores, and the wire core is made up of conductor 1 and the insulation layer 2 outside the conductor, and the sheath layer 4 is directly extruded outside the cable core. When extruding, aramid fiber rope is added to fill the gap in the middle of the wire core to form an anti-seismic layer 3 . Conductor 1 is twisted by the sixth conductor, and the pitch ratio of the outermost conductor is 12.

[0015] The above is only a preferred embodiment of the present invention, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, some improvements can also be made, and these improvements should also be regarded as the present invention. scope of protection.

Abstract

The invention discloses a seismic cable, which comprises a cable core formed by twisting a plurality of conductor cores. The conductor cores consist of conductors and insulating layers outside the conductors; a sheath layer is directly extruded outside the cable core; and an aramid rope is filled in a gap between the conductor cores so as to form a seismic layer. The seismic cable has excellent seismic performance, and can normally work when subjected to long-term high shaking force, a manufacturing process is simple, continuous production of seismic cables with a long length can be realized, and special equipment is not required.

Description

[0001] technical field [0002] The invention relates to a power cable, in particular to an anti-seismic cable. Background technique [0003] Anti-seismic cables are often used in long-term moving or vibration situations. At present, anti-seismic cables in my country are generally made of soft conductors extruded with rubber materials. During the vibration process, the sheath and conductors of this cable are used as load-bearing structures. Certain shockproof ability, but if the cable is subject to relatively large shock force for a long time, its sheath will be easily torn, and the conductor will be disconnected. Cables have a shortened lifespan and require frequent replacement and maintenance. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide an anti-seismic cable which has outstanding anti-seismic performance and can operate normally even under long-term large shock force. [0005] An anti-seismic cable accord...
