Abstract
The utility model discloses an overhead cable. The overhead cable comprises a cable core and an outer sheath; the cable core is composed of steel cores and aluminum cores stranded at the external surface of the steel cores; the outer sheath is covered on the outer surface of the cable core; and the outer sheath is a composite four-layer structure comprising a shielding layer, an insulating layer, an uvioresistant plastic material layer and a flame retardant layer from inside to outside. The overhead cable of the utility model has the advantages of water-proof, moisture-proof, fire retardant and shielding interference-resistant functions, and therefore, the service life of the overhead cable can be guaranteed.
Description
Technical field
This practicality relates to a kind of electric signal transmission instrument, is specifically related to a kind of overhead cable.
Background technology
Overhead cable is as the device of a kind of transmission of electric signals common in the daily life and used widely by people.Present overhead 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 overhead cable is easy to make moist, and therefore needs it to possess waterproof and dampproof function.And if breaking out of fire, overhead cable can become the medium of propagating fire very soon, this just needs overhead cable to have anti-flaming function.In addition, overhead cable need to shield well work of interference.But to reach simultaneously uvioresistant, fire-retardant and shielding disturbs these functions but to be difficult to.
Summary of the invention
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of overhead 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 adopts is: a kind of overhead cable, comprise cable core and oversheath, described cable core is made of steel core and the aluminium core that is stranded in the steel core outer surface, described oversheath is coated on the cable core outer surface, oversheath is four layers of composite construction, is followed successively by from inside to outside screen, insulating barrier, uvioresistant plastic material layer and flame-retardant layer.
As preferably, described steel core is seven strands.
As preferably, described aluminium core is six strands.
As preferably, described insulating barrier, uvioresistant plastic material layer and flame-retardant layer consistency of thickness.
The beneficial effects of the utility model are: 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.The uvioresistant plastic material layer can be resisted ultraviolet ray to a certain extent.Screen can shield interference signal, guarantees the normal operation of cable.Flame-retardant layer can be fire-retardant to a certain extent, prevents that cable from becoming the medium of fire-propagation.
