Abstract
The utility model discloses an overhead cable. The overhead cable comprises a cable core and an external sheath, wherein the cable core is composed of a steel core and an aluminum core twisted on the external surface of the steel core, the external sheath covers the external surface of the cable core, and the external sheath is of a four-layer composite structure orderly comprising a shielding layer, an insulating layer, a moisture-proof isolation layer and a flame-retardant layer from inside to outside. The overhead cable has the waterproof function, the moisture-proof function, the flame-retardant function and the interference shielding function, so that the service life of the overhead cable is ensured.
Description
Technical field
This practicality relates to a kind of signal of telecommunication delivery means, is specifically related to a kind of aerial cable.
Background technology
Aerial cable is as the device of a kind of transmission of electric signals common in the daily life and used widely by people.Present aerial cable is in order to satisfy the growing demand of people, and it is more diversified that function becomes.The long-term exposed to air of aerial cable is easy to make moist, and therefore needs it to possess waterproof and dampproof function.And if breaking out of fire, aerial cable can become the media of propagating fire very soon, this just needs aerial cable to have anti-flaming function.In addition, aerial cable need shield well work of interference.But to reach waterproof, protection against the tide simultaneously, fire-retardant and shielding disturbs these functions but to be difficult to.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and a kind of aerial cable is provided, and has waterproof, protection against the tide, fire-retardant, function that shielding is disturbed, guarantees its useful life.
The technical scheme that the utility model adopted is: a kind of aerial cable; Comprise cable core and oversheath; Said cable core is made up of steel core and the aluminium core that is stranded in the steel core outer surface; Said oversheath is coated on the cable core outer surface, and oversheath is four layers of composite construction, is followed successively by screen, insulating barrier, moistureproof separator and flame-retardant layer from inside to outside.
As preferably, said steel core is seven strands.
As preferably, said aluminium core is six strands.
As preferably, said insulating barrier, moistureproof separator and flame-retardant layer consistency of thickness.
The beneficial effect of the utility model is: cable core is by the aluminium core and steel core is stranded forms, and steel core mainly plays a part to gain in strength, and the aluminium core mainly works to transmit electric energy.Moistureproof separator can be moistureproof to a certain extent.Screen can shield interference signal, guarantees the operate as normal of cable.Flame-retardant layer can be fire-retardant to a certain extent, prevents that cable from becoming the media of fire-propagation.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: 1, steel core; 2, aluminium core; 3, screen; 4, insulating barrier; 5, moistureproof separator; 6, flame-retardant layer.
Embodiment
To combine accompanying drawing and specific embodiment that the utility model is done further explain below.
As shown in Figure 1; A kind of aerial cable; Comprise cable core and oversheath, said cable core is made up of steel core 1 and the aluminium core 2 that is stranded in steel core 1 outer surface, and said oversheath is coated on the cable core outer surface; Oversheath is four layers of composite construction, is followed successively by screen 3, insulating barrier 4, moistureproof separator 5 and flame-retardant layer 6 from inside to outside.As preferably, said steel core 1 is seven strands.As preferably, said aluminium core 2 is six strands.As preferably, said insulating barrier 4, moistureproof separator 5 and flame-retardant layer 6 consistency of thickness.
