Abstract
The utility model relates to a safe and reliable fire-fighting line, including a conductor, a ground line, a shielding layer and an insulating layer. The conductor includes two leads, which are respectively covered by an inner insulating layer, a glass fiber layer is cladding on the two leads and the inner insulating layers covering the leads, and the glass fiber layer and the ground line are covered by an outer insulating layer in common. With the structure, the insulation and moistureproof effects of a fire-fighting line is effectively raised, the structure is stable, reliability is good, and reliable line material can be provided for the fire-fighting line of a building.
Description
Technical field
The utility model relates to electric wire, a kind of fire line of saying so exactly, and this fire line is safe and reliable.
Background technology
In various buildings; In order to guarantee safety, the fire-fighting circuit of fire alarm must be set, common fire alarm construction and acceptance specification require above-mentioned fire alarm fire-fighting circuit must apply mechanically coating steel pipe; And the coating steel pipe skin also will be brushed fire resistant coating; 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, is not influenced by fire.
The designing requirement of fire alarm fire-fighting 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 safe and reliable fire line the order of the utility model, this fire line structure is firm, and insulation effect is good.
Be to provide a kind of safe and reliable fire line another order of the utility model, this fire line fire prevention, protection against the tide, easy to make, with low cost, can be widely used in the fire-fighting circuit 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 safe and reliable fire line; It includes conductor, ground wire, screen and insulating barrier; It is characterized in that said lead has two; Be coated with inner insulating layer respectively, a glass layer coats the inner insulating layer of two leads and coated wire, and glass layer and ground wire are coated by external insulation layer jointly.
Said fire line also is provided with screen, and screen is arranged between glass layer and ground wire and the external insulation layer, avoids interference from outside signals.
Above-mentioned screen, it preferably is arranged on the inwall of external insulation layer, is convenient to the fixing and processing of screen.
Above-mentioned screen is the inside aluminium foil layer of conductive layer.
Said two leads and ground wire are isosceles triangle and distribute, and help increasing stability of structure, reduce the volume of fire line.
The utility model adopts above-mentioned structure, has improved the insulation effect and the moisture effect of fire line effectively, and structure is firm, and good reliability can provide reliable wire rod for the fire-fighting circuit 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 glass layer, and 4 is ground wire, and 5 is screen, and 6 is external insulation layer.
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 glass layer 3, form protection and protection against the tide to lead 1.
Screen 5 is coating lead 1 and ground wire 4, and the outside of screen 5 coats external insulation layer 6 more then, when making, generally screen is arranged on the inwall of external insulation layer 6.
Through this structure, can improve the insulation effect and the moisture effect of the utility model widely, and structure is firm, reliable.
Lead 1 adopts naked copper to make with ground wire 4 usually, and inner insulating layer 2 adopts silica gel to make, and 6 of external insulation layers adopt the insulating material of low-smoke halogen-free material to make, and 5 of screens adopt the inside aluminium foil of conductive layer to make.
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. safe and reliable fire line; It includes conductor, ground wire, screen and insulating barrier; It is characterized in that said lead has two; Be coated with inner insulating layer respectively, a glass layer coats the inner insulating layer of two leads and coated wire, and glass layer and ground wire are coated by external insulation layer jointly.
2. safe and reliable fire line as claimed in claim 1 is characterized in that this fire line also is provided with screen, and screen is arranged between glass layer and ground wire and the external insulation layer.
3. safe and reliable fire line as claimed in claim 2 is characterized in that above-mentioned screen, and it is arranged on the inwall of external insulation layer.
