Abstract
The utility model relates to a fire prevention vision cable. The vision cable is burnt very easily and causes the short circuit to have a power failure to cause bigger loss or even tragedy to take place. The utility model discloses a conductive core, its characterized in that conductive core sets gradually high foam insulation layer, dampproofing type plastic -aluminum composite bed, iron shielded layer, pottery silica gel layer, flame retardant coating and fire -retardant sheath outward. Fire -retardant sheath for there not being the steamed low fire -retardant high temperature resistant nanometer modified polyolefin polymeric material of cigarette. The utility model has the advantages of added pottery silica gel layer and mica tape, greatly guaranteed effective transmission of video information when the conflagration takes place, for effective the relief of disaster provides the assurance, the while will not have steamed low fire -retardant sheath material of cigarette and the comprehensive combination of fireproof cable technique, make fire prevention coaxial cable price / performance ratio demonstrated fully.
Description
Technical field
The utility model relates to a kind of electric wire, especially a kind of fire prevention vision cable.
Background technology
The requirement of development to electric wire of building house ornamentation is also more and more higher, the fire caused due to electric wire senile cause in decades in past frequently occurs, electric wire market type is various, but the performance of real fire protection flame retarding is all relatively weak, vision cable is easy to be caused short circuit power cut by burning, thus the even tragedy that results in greater loss occurs.Therefore the vision cable with fire protection flame retarding function of high performance and long service life be market in the urgent need to product.
Utility model content
The object of the utility model patent to provide a kind of fire prevention vision cable, and greatly ensure that effective transmission of video information when fire occurs, for effective disaster relief provides guarantee, fire protection flame retarding is good, and the life-span is permanent.
The technical solution of the utility model is: a kind of fire prevention vision cable, comprise conductor wire core, it is characterized in that outside described conductor wire core, setting gradually high-foaming insulating barrier, the plastic-aluminum combined layer of damp-proof, metal screen layer, ceramic layer of silica gel, flame retardant coating and fire retardant jacket.
Described fire retardant jacket is the high-temperature resistant nano modification polyolefin polymeric material of LSOH anti-flaming.
Described metal screen layer is layer that copper is encoded.
Described flame retardant coating is two-layer, and internal layer is mica layer, and skin is glass fiber belt.
Described conductor wire core is at least 2, and the cross section of conductor wire core is circular.
Described conductor wire core is formed by concentric type is stranded by the soft round copper wire that some diameters are identical.
The beneficial effects of the utility model are:
1. with the addition of ceramic layer of silica gel and mica tape, effective transmission of video information is greatly ensure that when fire occurs, for effective disaster relief provides guarantee, LSOH anti-flaming sheath material and fireproof cable versatility are combined simultaneously, fire prevention coaxial cable cost performance is found full expression.
2. ceramic layer of silica gel, have softness, Halogen, nontoxic, tasteless, human body, natural environment are had no adverse effects, the flue gas after burning is very little, does not have smoke toxicity, to human body fanout free region.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is technological process of the present utility model.
In figure: 1. conductor wire core 2. high-foaming insulating barrier 3. damp-proof plastic-aluminum combined layer 4. metal screen layer 5. ceramic layer of silica gel 6. flame retardant coating 7. fire retardant jacket.
Embodiment
One fire prevention vision cable as depicted in figs. 1 and 2, sets gradually high-foaming insulating barrier 2, the plastic-aluminum combined layer 3 of damp-proof, metal screen layer 4, ceramic layer of silica gel 5, flame retardant coating 6 and fire retardant jacket 7 outside conductor wire core 1.Fire retardant jacket is the high-temperature resistant nano modification polyolefin polymeric material of LSOH anti-flaming.Metal screen layer is layer that copper is encoded, and flame retardant coating is two-layer, and internal layer is mica layer, and skin is glass fiber belt.Conductor wire core is at least 2, and the cross section of conductor wire core is circular.Conductor wire core is formed by concentric type is stranded by the soft round copper wire that some diameters are identical.
The utility model effectively can prevent the generation of fire incident, and two is once breaking out of fire effectively can ensure that the transmission of video information and the definition of video pictures are that the promptness of the disaster relief and validity provide reliable guarantee.
