Abstract

The invention discloses a kind of fire resisting heat absorption electric wire, including the aluminium alloy conductor positioned at center and the woven shield being extruded in outside aluminium alloy conductor, fire resistant coating is coated with woven shield, the multiple tongues of extrusion molding on fire resistant coating, the filling heat absorption cotton in tongue.The electric wire does not injure while high intensity is kept, to human body, easy to process, fire resistance is stablized, and can directly use, and the occasion that can have stringent limitation in laying narrow space, the structure size to cable and have fire resistance uses.

Description

A kind of fire resisting heat absorption electric wire
Technical field
The invention belongs to field of cables, particularly a kind of fire resisting heat absorption electric wire.
Background technology
With taking place frequently for fire incident, people, which recognize electric wire fire risk, constantly to deepen, and relevant department is to electricity The requirement of the performances such as line fireproofing and block burn of cable is also higher and higher.Since electric wire fire has, sprawling is fast, it is difficult to put out a fire to save life and property, produces two Secondary harm, the features such as recovery time is long, can bring huge loss to the lives and properties of national economy and the people.Because of this person Harsher service condition is proposed to the fire performance of electric wire, security reliability.Such as fire prevention, explosion-proof, overload energy Power is strong, and service life length, under Fire Conditions, Fire lift, fire pump need to keep the normal operation in certain time, and cable exists There is low-smoke low-halogen low toxicity characteristic, the particular/special requirements such as even up to smokeless halogen-free is nontoxic after burning.
The important public place decoration such as the office building of modernization, hotel, restaurant, railway station is more and more luxurious, uses Combustible is more and more;Under conditions of being required as these important public places once catching fire, electric wire can normally continually It is the escape of people, automatic alarm that ground, which transmits electric power, conveys various control signals and alarm signal, and the startup of fire fighting device, rescue And the use of emergency set provides valuable time, and fire-resistant wires are exactly to ensure circuit in certain time when fire occurs Normal power-up, the various control signals of transmission, alarm signal.It is the illumination of passage during meeting event of fire, emergent broadcast, anti- The normal power supply of fiery warning device, automatic fire-fighting facility and other emergency sets, makes personnel evacuate in time, enables rescue work It is normally carried out;Also some fire-resisting cables are not all right due to radiating, and cause naturally, bringing harm, therefore the reliability of fire-resistant wires is extremely Close important.
The content of the invention
The present invention is to overcome shortcoming existing in the prior art, there is provided a kind of fire resisting heat absorption electric wire, the electric wire are keeping high While intensity, human body is not injured, easy to process, fire resistance is stablized.
A kind of fire resisting heat absorption electric wire of the present invention, including aluminium alloy conductor positioned at center and be extruded in aluminium alloy and lead The woven shield in external face, is coated with fire resistant coating, the multiple tongues of extrusion molding on fire resistant coating, in tongue in woven shield Interior filling heat absorption cotton.
Further as above-mentioned technical proposal is improved, and the fire resistant coating is ceramic silicone rubber fireproof layer or mineral fire prevention Layer.
As an alternative to the above-described technical solution, the woven shield is fireproof glass silk, steel wire, steel wire and fibre Tie up silk mixed weaving structure, copper wire, tinned copper wire or with filament mixed weaving structure.
Beneficial effects of the present invention are:
After small outside diameter fire-resistant wires of the present invention, fire-resistant silicon rubber coating and braiding layer are less than the wrapped mica of the prior art Extrusion insulation directly extrudes hot-face insulation, and the integrated thickness of fire-resistant silicon rubber coating and braiding layer is only to extrude insulation thickness 40-80%, significantly reduce the outside diameter of electric wire, can have strictly in laying narrow space, the structure size to cable Limitation and have fire resistance occasion use.During processing, mica powder is not had human body is damaged;The fire resisting silicon of coating Rubber coating makes product have preferable insulation performance, and organization level ensure that the mechanical strength of product at the same time again.Under normal conditions, produce Product are soft.When a fire, the fire-resistant silicon rubber coating burns of coating, make silicon rubber form ceramic protective layer, in fire In the case of ensure that electric power, communication it is unimpeded.In addition, the multiple tongues of extrusion molding on fire resistant coating, the filling heat absorption cotton in tongue, Heat in cable is absorbed and distributed outward so that the hidden danger that cable will not be produced from but bring.
Brief description of the drawings
The structure diagram of Fig. 1 present invention.
Embodiment
Elaborate below in conjunction with the accompanying drawings to embodiments of the present invention.
As shown in Figure 1, a kind of fire resisting heat absorption electric wire, including aluminium alloy conductor 1 positioned at center and it is extruded in aluminium alloy and leads The woven shield 2 in external face, fire resistant coating 3 is coated with woven shield, the multiple tongues 4 of extrusion molding on fire resistant coating, Filling heat absorption cotton 5, the heat in cable is absorbed and distributed outward in tongue so that cable will not occur certainly because temperature is excessive Combustion.
The fire resistant coating is ceramic silicone rubber fireproof layer or mineral fireprotection layer;The woven shield is fireproof glass Silk, steel wire, steel wire and filament mixed weaving structure, copper wire, tinned copper wire or with filament mixed weaving structure.
Under normal conditions, product is soft;When a fire, the fire-resistant silicon rubber coating burns of coating, form silicon rubber Ceramic protective layer, protects the conductor of electric wire not to be damaged.
Concrete application approach of the present invention is very much, and the above is only the preferred embodiment of the present invention, it is noted that for For those skilled in the art, without departing from the principle of the present invention, some improvement can also be made, this A little improve also should be regarded as protection scope of the present invention.
