Abstract
The utility model relates to a dampproof and fireproof alarming wire comprising a conduct, a ground wire, a shielding layer and insulating layers, wherein two conducting wires are arranged and respectively wrapped with an inner insulating layer; the two conducting wires and the inner insulating layer of the conducting wires are wrapped by the shielding layer; both the shielding layer and the ground wire are wrapped by an outer insulating layer. According to the utility model, the structure is adopted to ensure that the insulating effect and the dampproof effect of the fireproof insulated wire are effectively improved, the structure is stable and the reliability is good, therefore, reliable wire rods can be provided for dampproof and fireproof alarming circuits of buildings.
Description
Technical field
The utility model relates to electric wire, the fireproof alarming line of a kind of protection against the tide of saying so exactly, and this moistureproof fireproof alarming line is safe and reliable.
Background technology
In various buildings,, the fire alarm circuit must be set in order to guarantee safety; Common fire alarm construction and acceptance specification require above-mentioned fire alarm circuit must apply mechanically coating steel pipe; And the coating steel pipe skin also will brush fire resistant coating, and the thickness requirement of fire resistant coating is that the fire-fighting system circuit does not cut off the power supply after will guaranteeing breaking out of fire like this more than 2 millimeters; Not by the fire influence, proceed emergent broadcast operation and Central Control Room call command.
The designing requirement of fire alarm circuit is too high, though be for the purpose of safety, in the application of reality; Circuit does not often use; This can cause that aging circuit, coating steel pipe get rusty etc. variety of issue, the coating steel pipe structure of outsourcing is not utilized the maintenance and the maintenance of circuit, and this structural design; Improve installation and cost of manufacture greatly, caused the waste of resource.
Summary of the invention
Based on this, provide a kind of fireproof alarming line of safe and reliable protection against the tide the order of the utility model, this fireproof alarming line structure is firm, and insulation effect is good.
Be to provide a kind of fireproof alarming line of protection against the tide another order of the utility model, the fire prevention of this fireproof alarming line, protection against the tide, easy to make, with low cost, can be widely used in the fireproof alarming circuit of protection against the tide of various buildings, and be convenient to safeguard.
In order to reach above-mentioned order ground, the utility model is realized according to following mode.
A kind of fireproof alarming line of protection against the tide; It includes conductor, ground wire, screen and insulating barrier, it is characterized in that said lead has two, is coated with inner insulating layer respectively; One screen coats the inner insulating layer of two leads and coated wire, and screen and ground wire are coated by external insulation layer jointly.
Said lead and inner insulating layer, its outside protective layer that coats earlier, the conductively-closed layer coats again.Can increase the insulation effect of lead like this, the phenomenon of avoiding leaking electricity takes place.
Said screen is the outside aluminium foil layer of conductive layer.
The external insulation layer inwall has a diaphragm, increases insulation effect and moisture effect.
Said two leads and ground wire are isosceles triangle and distribute, and help increasing stability of structure, reduce the volume of moistureproof fireproof alarming line.
The utility model adopts above-mentioned structure, has improved the insulation effect and the moisture effect of fire-proof insulation line effectively, and structure is firm, and good reliability can provide reliable wire rod for the fireproof alarming circuit of the protection against the tide of building.
And the utility model is easy to realize that cost of manufacture and installation cost are cheap, is convenient to wiring.
Description of drawings
The cross-sectional view that Fig. 1 implements for the utility model.
Embodiment
Below, shown in accompanying drawing, the practical implementation of the utility model is elaborated.
Shown in Figure 1, be the cable cross-sectional view of the utility model, among the figure, 1 is lead, and 2 is inner insulating layer, and 3 is protective layer, and 4 is screen, and 5 is diaphragm, and 6 is external insulation layer, and 7 is ground wire.
Wherein, two leads 1 are distribution up and down in the drawings, and the outside of every lead 1 all is coated with inner insulating layer 2, will be coated with two leads, 1 coating of insulating barrier 2 then through a protective layer 3, again protective layer 3 external packets are covered with screen 4.
The outside of screen 4 and ground wire 7 coats external insulation layer 6 again, and simultaneously, the inwall of external insulation layer 6 also has a diaphragm 5.
Through this structure, can improve the insulation effect and the moisture effect of the utility model widely, and structure is firm, reliable.
In a word, the above is merely the preferred embodiment of the utility model, is not the scope that is used for limiting the utility model embodiment.Be that all equalizations of being done according to the utility model claim change and modification, all in the claim of the utility model.
Claims (4)
1. the fireproof alarming line of a protection against the tide; It includes conductor, ground wire, screen and insulating barrier, it is characterized in that said lead has two, is coated with inner insulating layer respectively; One screen coats the inner insulating layer of two leads and coated wire, and screen and ground wire are coated by external insulation layer jointly.
2. the fireproof alarming line of protection against the tide as claimed in claim 1 is characterized in that said lead and inner insulating layer, its outside protective layer that coats earlier, and the conductively-closed layer coats again.
