Abstract
The utility model discloses a novel flame-retardant lead, comprising a conductor core and an oversheath. The conductor core is composed of a steel core and an aluminum core intertwsited outside the steel core; and the conductor core is wrapped in the oversheath which is of a three-layer composite structure successively including a shielding layer, an insulating layer and a moisture-proof isolating layer from inside to outside, wherein the insulating layer is made of furfuryl alcohol resin. The novel flame-retardant lead is good in insulating performance and flame retardation.
Description
Technical field
The utility model relates to a kind of electric signal transmission instrument, is specifically related to a kind of novel flame-retardant wire.
Background technology
Wire is the thing that arrives commonly used in our daily life.For wire can better use, generally all can one deck insulated hull be set in the wire outside.Now, very multiconductor insulated hull is all to adopt the materials such as polyvinyl chloride, fluoroplastics, polystyrene to make.But the burning-point of these materials is very low, and is very inflammable.Therefore, when short circuit or electric current just be easy to burning when excessive.Be easy to like this cause fire, cause great loss.
The utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, and a kind of novel flame-retardant wire is provided, and insulation property are good, and can be well fire-retardant.
The technical scheme that the utility model adopts is: a kind of novel flame-retardant wire, comprise wire stylet and oversheath, described wire stylet is made of steel core and the aluminium core that is stranded in the steel core outer surface, described oversheath is coated on the wire stylet outer surface, oversheath is three-layer composite structure, is followed successively by from inside to outside screen, insulating barrier, moistureproof separator.Described insulating layer material is furfuryl alcohol resin.
As preferably, described steel core is seven strands.
As preferably, described aluminium core is six strands.
The beneficial effects of the utility model are: wire stylet 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 normal operation of wire.Insulating layer material is furfuryl alcohol resin, can play good insulation effect, and can be fire-retardant to a certain extent, prevents that wire from becoming the medium of fire-propagation.
Description of drawings
Fig. 1 is the utility model structural representation.
In figure: 1, steel core; 2, aluminium core; 3, screen; 4, insulating barrier; 5, moistureproof separator.
Embodiment
Below in conjunction with the accompanying drawings and the specific embodiments the utility model is described in further detail.
As shown in Figure 1, a kind of novel flame-retardant wire, comprise wire stylet and oversheath, described wire stylet is made of steel core 1 and the aluminium core 2 that is stranded in steel core 1 outer surface, described oversheath is coated on the wire stylet outer surface, oversheath is three-layer composite structure, is followed successively by from inside to outside screen 3, insulating barrier 4, moistureproof separator 5.Described insulating barrier 4 materials are furfuryl alcohol resin.As preferably, described steel core 1 is seven strands.As preferably, described aluminium core 2 is six strands.
Insulating barrier 4 materials are furfuryl alcohol resin, and this material forms by refining in furfural, can play good insulation effect, and can be fire-retardant to a certain extent, prevents that wire from becoming the medium of fire-propagation.And this material price is cheap, also is easy to obtain, and has facilitated people's use.
