Abstract
The invention discloses a kind of electric wire, including conductor, conductor is combined conductor, and using the combination of copper and meltable conductor, the wherein centre of combined conductor is meltable conductor, is around stranded copper cash or tinned wird；Wherein meltable conductor is silver, lead, tin or their alloy, insulating barrier, hard protection layer, fire-proof high-temperature resistant layer and oversheath are enclosed with outside the conductor successively, the cross section of the conductor and insulating barrier is all circle, and the cross section of the hard protection layer, fire-proof high-temperature resistant layer and oversheath is triangle.The advantage of the invention is that：The electric wire further reduces the fusing time of meltable electric wire, you can the short-circuit of circuit is implemented to protect, and also the overload of circuit can be implemented to protect, while also preventing fires and not easily damaged.
Description
Technical field
The present invention relates to technical field of electric power, more particularly to a kind of electric wire.
Background technology
The transmission of electricity is typically what is realized by electric wire.Existing electric wire includes two parts, conductor and insulating barrier, conductor
For transmitting electric power, insulating barrier is wrapped in the outer surface of conductor, prevents electric leakage.But sometimes due to electric wire is short-circuit in itself, or,
Voltage excess load, or, the reason such as on fire, causes electric wire on fire outside electric wire.After electric wire is on fire, its burning velocity is very fast,
Made if the insulating barrier of electric wire outer layer covers is clinker, itself is just inflammable, particularly in the case of energization, Neng Gou
Serious fire is caused in short time, huge loss is caused to the people and country.In addition, existing electric wire is possible to place
In the environment trampled or extruded, traditional circle, which is extruded or trampled, easily causes electric wire breakage, causes disaster of leaking electricity, because
This existing electric wire is still defective.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of being capable of fire-retardant fireproof and the not easily damaged electric wire of anti-extrusion.
In order to solve the above technical problems, the technical scheme is that：A kind of electric wire, its innovative point is：Including conductor,
Conductor is combined conductor, and using the combination of copper and meltable conductor, the wherein centre of combined conductor is meltable conductor, around to be stranded
Copper cash or tinned wird；Wherein meltable conductor is to be enclosed with insulation successively outside silver, lead, tin or their alloy, the conductor
Layer, hard protection layer, fire-proof high-temperature resistant layer and oversheath, the cross section of the conductor and insulating barrier is all circle, the hard
The cross section of overcoat, fire-proof high-temperature resistant layer and oversheath is triangle.
Further, there is separation layer between the conductor and the insulating barrier.
Further, the separation layer is Mica tape layer or fiberglass cloth tape lapping layer.
Further, it is also filled with rubber between the insulating barrier and hard protection layer.
Further, the cross section of the hard protection layer, fire-proof high-temperature resistant layer and oversheath is equilateral triangle.
The advantage of the invention is that：
（1）The electric wire further reduces the fusing time of meltable electric wire, you can the short circuit to circuit is implemented to protect, also can be to circuit
Overload implement protection, while also fire prevention and it is not easily damaged；
（2）There is separation layer between conductor and the insulating barrier, can further improve the insulating properties of meltable cable, it is also favourable
In the separation of insulating barrier；
（3）Separation layer is Mica tape layer or fiberglass cloth tape lapping layer, further increases the fire-retardant anti-of meltable electric wire
Fiery performance；
（4）Rubber is also filled between insulating barrier and hard protection layer, it is possible to reduce the sky between insulating barrier and hard protection layer
Gap, reduction friction, further effectively prevents extruding, protects electric wire not by breakage；
（5）The cross section of hard protection layer, fire-proof high-temperature resistant layer and oversheath is equilateral triangle, because triangle is firm in itself
Shape, so the electric wire of triangle can effectively buffer extruding dynamics, protect electric wire not by breakage.
Brief description of the drawings
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
Fig. 1 is a kind of structural representation of electric wire of the invention.
Embodiment
The following examples can make professional and technical personnel that the present invention is more fully understood, but therefore not send out this
It is bright to be limited among described scope of embodiments.
As shown in figure 1, a kind of electric wire, including conductor 1, conductor 1 is combined conductor, using the combination of copper and meltable conductor,
Wherein the centre of combined conductor is meltable conductor, is around stranded copper cash or tinned wird；Wherein meltable conductor be silver, lead,
Tin or their alloy, conductor 1 is outer to be enclosed with insulating barrier 2, hard protection layer 3, fire-proof high-temperature resistant layer 4 and oversheath 5 successively,
There is separation layer 6 between conductor 1 and insulating barrier 2, separation layer 6 is Mica tape layer or fiberglass cloth tape lapping layer, insulation
Rubber 7 is also filled between layer 2 and hard protection layer 3, and the cross section of conductor 1 and insulating barrier 2 is all circle, hard protection layer 3,
The cross section of fire-proof high-temperature resistant layer 4 and oversheath 5 is triangle, the horizontal stroke of hard protection layer 3, fire-proof high-temperature resistant layer 4 and oversheath 5
Section is equilateral triangle.
The general principle and principal character and advantages of the present invention of the present invention has been shown and described above.The skill of the industry
Art personnel are it should be appreciated that the present invention is not limited to the above embodiments, and described in above-described embodiment and specification is explanation
The principle of the present invention, without departing from the spirit and scope of the present invention, various changes and modifications of the present invention are possible, these
Changes and improvements all fall within the protetion scope of the claimed invention.The claimed scope of the invention by appended claims and
Its equivalent thereof.
