Abstract
The invention discloses a fireproof armored cable which comprises a cable core formed by twisting a plurality of wire cores, wherein the wire core comprises a middle conductor, a fireproof layer and an insulated layer; the fireproof layer and the insulated layer are arranged outside the middle conductor; an inorganic filler layer is arranged in the gap of the cable core and outside the cable core; an inner protection layer, an inorganic thermal insulation layer, an armored layer and an outer protection layer are arranged outside the inorganic filler layer in sequence. The inorganic filler layer is formed by rope-shaped inorganic material, the inorganic thermal insulation layer is formed by two layers of high flame-retardant glass tapes and a synthetic mica paper adhered and clipped between the two layers of the high flame-retardant glass tapes, so as to play a very good heat insulation role in fire hazard, thus the insulation layer of the cable is softened in the fire hazard but not melted. The armored layer is formed by armoring steel belt, so as to bear the external force, fix the cable structure and insulate the fire, thus the cable is not easy to impact to be destroyed in the fire hazard, the relatively long-time normal operation of the cable in the fire hazard is ensured and the power supply guarantee is given to person evacuation and rescue.
Description
?
Technical field
The present invention relates to a kind of power cable, specifically is a kind of fire-resistant armoured cable.
Background technology
General fire-resisting cable all adopts the wrapped mica in conductor outside to bring to reach fire-resistant effect; But often follow various collisions of rocking with junk in the fire; Possibly making originally, more firm flame retardant coating becomes lax; Even dissipate, cause cable owing to puncture short cuts off the power supply, all brought the deuce to pay for personnel escape and rescue.
Summary of the invention
Technical problem to be solved by this invention provides a kind of armoured cable with good fire resistance.
A kind of fire-resistant armoured cable of the present invention; It comprises the cable core that is twisted into by some cores; Said core is made up of the conductor of centre and flame retardant coating and the insulating barrier that is arranged on outside the conductor, is provided with inorganic packed layer in the slit and the outside of cable core, outside inorganic packed layer, sets gradually sheath; Inorganic thermal insulation layer, armour and outer jacket.
Said inorganic packed layer is made up of the rope form inorganic material, and this inorganic material possibility is a glass fiber.
Said inorganic thermal insulation layer becomes mica paper to constitute by sticking clamping in the middle of the two-layer high flame retardant glass strap.
Beneficial effect of the present invention:
Inorganic packed layer among the present invention is made up of the rope form inorganic material, and inorganic thermal insulation layer becomes mica paper to constitute by sticking clamping in the middle of the two-layer high flame retardant glass strap, and making the inorganic material tape thickness is about 2mm; In fire, play good refractory heat-insulating effect; Make the insulating barrier of cable in fire, be softened and not melt, armour is formed by steel-tape armouring, except bearing the external force effect; Also play the effect of the firm construction of cable and fire insulation; Cable can not impacted in fire easily and destroy, confirmed the ability of the normal operation longer time of cable in fire, brought the power supply assurance for evacuating personnel and rescue.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
As shown in Figure 1; A kind of fire-resistant armoured cable of the present invention, it mainly comprises the cable core that is twisted into by some cores, wherein core is made up of with insulating barrier 3 conductor 1 of centre and the flame retardant coating 2 that is arranged on outside the conductor; Slit and outside at cable core are provided with inorganic packed layer 4; Outside inorganic packed layer 4, set gradually sheath 5, inorganic thermal insulation layer 6, armour 7 and outer jacket 8.Inorganic packed layer 4 is made up of the rope form inorganic material, glass fiber for example, and inorganic thermal insulation layer 6 becomes mica paper to constitute by sticking clamping in the middle of the two-layer high flame retardant glass strap.
The above only is a preferred implementation of the present invention, should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also make some improvement, and these improvement also should be regarded as protection scope of the present invention.
