Abstract
A fire-proof signal cable comprises signal wires, wherein the signal wires are twisted in pairs to obtain a cable core; a flame-retardant strap is wound outside the cable core; a shielding layer is woven outside the flame-retardant strap; a mica tape and a glass fiber strap are sequentially wound outside the shielding layer; a glass fiber fire-proof layer is woven outside the glass fiber strap; and high-temperature-resistant, flame-retardant and anti-corrosion paint coats the fire-proof layer. The first flame-retardant layer, the shielding layer, the first fire-proof layer, the second flame-retardant layer, the second fire-proof layer and a protecting layer are sequentially arranged outside the signal wires. The fire-proof signal cable is excellent in fire-proof and flame-retardant performance and excellent in anti-corrosion performance; the signal wires can safely transmit data or power signals for a long time under the condition of flame combustion, the signals are transmitted stably and precisely, characteristic impedance is high, and the strength is excellent.
Description
Technical field
The invention belongs to field of cable technology, be specifically related to a kind of fire resistance signal cable.
Background technology
Important department and the public place request signal transmission fire protection flame retardings such as skyscraper, subway, power plant, nuclear power station, tunnel, and do not prolong combustion, ensure that in ablaze situation, still can maintain certain hour normal power-up runs, and timely signal transmission, make personnel have regular hour safe escape when breaking out of fire.
Summary of the invention
The object of this invention is to provide a kind of fire resistance signal cable, the fire protection flame retarding time is long, and does not prolong combustion, and the personnel that ensure that have regular hour safe escape and can timely signal transmission when breaking out of fire.
The technical solution adopted in the present invention is: a kind of fire resistance signal cable, comprises holding wire, and described holding wire pair twist stranding forms cable core, and the outer wrapped inhibiting tape of cable core; The outer woven shield of described inhibiting tape, screen wrapped mica tape and glass fibre belt successively outward, the outer braided glass filament flame retardant coating of glass fibre belt, flame retardant coating applies heat-resistant fireproof corrosion resistant coating outward.
Described Mica tape is two-layer.
Described heat-resistant fireproof corrosion resistant coating apply three layers and more than.
The conductor wire core that described holding wire is closed by tin-plating round copper wire bundle and the teflon insulation layer extruded outside conductor wire core are formed.
The invention has the beneficial effects as follows: holding wire of the present invention has the first flame-retardant layer, screen, the first flame retardant coating, the second flame-retardant layer, the second flame retardant coating and protective layer outward successively; fire retardant performance is superior; antiseptic property is excellent; ensure that holding wire can keep long period safety-oriented data transfer or power supply signal in flame combustion situation, and stable signal transmission is accurate, characteristic impedance is good, good strength.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is cross-sectional view of the present invention.
Embodiment
Below in conjunction with accompanying drawing 1,2 and embodiment, the present invention is described in detail.
A kind of fire resistance signal cable, comprises 10 holding wires 9, and described 10 holding wire 9 pair twist strandings form cable core, and the outer wrapped inhibiting tape 6 of cable core; The outer woven shield 5 of described inhibiting tape 6, the outer wrapped two-layer mica tape 4 of screen 5, the outer wrapped glass fibre belt 3 of mica tape 4, the outer braided glass filament flame retardant coating 2 of glass fibre belt 3, the outer coating of flame retardant coating 2 three layers of heat-resistant fireproof corrosion resistant coating 1.The conductor wire core 8 that described holding wire 9 is closed by tin-plating round copper wire bundle and the teflon insulation layer 7 extruded outside conductor wire core 8 are formed.
The present invention adopts 28 diameters to be that the tin-plating round copper wire of 0.15mm becomes soft bent conductor wire core 8 by 4+9+15 layer-stranding, with corrosion-resistant, density is low, Heat stability is good, high temperature resistant 200 DEG C, electrically and the polytetrafluoroethylene of good mechanical performance extrude nominal thickness 0.45mm insulating barrier 7.The inhibiting tape 6 that the bandwidth adopting fire resistance, electric property, Good Heat-resistance is 25mm, tape thickness is 0.1mm wrapped one deck of Duplication using 30% is as the first flame-retardant layer, weave one deck screen 5 with the tin-plating round copper wire that 144 diameters are 0.20mm again, ensure that any interference source does not have interference to signal transmission.One-tenth cable core adopts the mica tape 4 that the bandwidth of mechanical property, electric property, resistance to ag(e)ing, Good Heat-resistance is 25mm, tape thickness is 0.1mm wrapped two-layer as the first flame retardant coating using certain pitch, increases fire-resistant, the resistance to elevated temperatures of cable; The outer wrapped bandwidth of the first flame retardant coating be 25mm, tape thickness is that fire-retardant, the fire prevention glass fibre belt 3 of 0.15mm is as the second flame-retardant layer, the fire resistance of further increase cable, adopt 6 strands, 24 ingot again, filament diameter be 0.25 fireproof glass silk work out the second flame retardant coating 2, improve further the fire-resistant effect of cable.Outside the second flame retardant coating 2, apply three layers of heat-resistant fireproof corrosion resistant coating 1 again as protective layer, not only there is fireproofing function, and there is corrosion-resisting function.
The invention is not restricted to above-described embodiment, can increase or reduce the radical of holding wire as required, and external diameter, holding wire color, conductor wire core diameter etc. all can change as required.
