Abstract
The invention relates to a fireproofing high-flexible data signal transmission cable. A cable core is formed by at least twisting a pair of twisted pair and an insulated wire core comprising at least one core, wherein the twisted pair is externally provided with a split-phase composite shielding layer and a split-phase wrapping layer; the cable core is externally provided with a finished cable wrapping layer, a high fireproofing nanoscale ceramic silicone rubber inner protective layer, a general composite shielding layer, a wrapping insulation layer and a high fireproofing nanoscale ceramic silicone rubber outer protective layer sequentially; and high fireproofing halogen-free fillers are arranged in a clearance between the cable cores. The cable provided by the invention has favorable electrical performance and excellent fire resistance performance and anti-electromagnetic interference performance, and can meet the use requirement well.
Description
Technical field
The present invention relates to a kind of fire prevention high flexibility data cable, belong to the cable technology field.
Background technology
According to the fast development of China's industrial automation, industrial central control system more and more widely, through connecting PLC processor, I/O, computer, operator interface and other smart machines, Control Network makes that it reaches in real time, the requirement of high throughput application.Demand sharp increase to high-speed interconnect; Mainly concentrate on precision instrumentation, intelligent machine field device, operation and Data Control automatically; Be included in fields such as specific (special) requirements occasions such as realizing peer-to-peer information transmission, teleprogram design, fault eliminating and I/O renewal and the interlocking of PLC processor, painting workshop and assembly line, water/waste water treatment, food processing, pharmacy and classification conveyer on the same cable and control, security protection, vehicle automobile automatic assembly line, instrument, video; These occasions require high-speed data transmission cable; Want to satisfy the requirement that information is transmitted, and possess high electrical property and good fire resistance ability and anti-electromagnetic interference capability, still inhibit signal transmission under the situation of fire; Help fire-fighting command and evacuating personnel, minimizing personnel and property loss.
Because the particularity that this kind cable requires generally from national imports such as the U.S., Korea S, along with the raising of related electric home-made equipment level, makes this special cable also will domesticize in order to reduce cost.
Summary of the invention
The object of the invention is exactly for adapting to the demand in market; Overcome the deficiency that existing normal cable exists; Provide a kind of electrical property, transmission performance, interference free performance and fire protecting performance of cable of making superior; The data of cable, fire prevention, Halogen, each item performance index such as nontoxic and smokeless can compare favourably with external like product; And have high temperature resistant, seawater corrosion resistance, insulation property are high, fire line is good, puncture voltage is high, heat-resistance index is big, the anti-mechanical damage of tension, anti-electromagnetic interference and anti-inside and outside electrostatic interference superior performance, and low electric capacity, low inductance, nontoxic non smoke, fire prevention high flexibility data cable that light transmittance is high.
The objective of the invention is to realize that through following technical scheme the insulated wire cores by a pair of twisted wire pair and at least one core is twisted into cable core at least, its center line externally is provided with phase-splitting composite shielding layer and phase-splitting lapping layer; The cable core peripheral hardware sets gradually stranding lapping layer, high fire prevention nanometer scale ceramics silicon rubber sheath, total composite shielding layer, wrapped separator, high fire prevention nanometer scale ceramics silicon rubber outer jacket, and high fire prevention Halogen inserts is set in the space between the cable core.
Described phase-splitting lapping layer adopts double layer thin environmental protection polyester belt.
Described stranding lapping layer adopts high fire prevention glass fibre belt.
Described phase-splitting composite shielding layer adopts plastic-aluminum band lapped shielding layer and tin-coated copper core woven shield with total composite shielding layer, and tin-coated copper core woven shield is arranged on the plastic-aluminum band lapped shielding layer.
Described wrapped separator adopts high fire prevention glass fibre belt.
Described high fire prevention Halogen inserts adopts high fire prevention glass rope.
Conductor in said twisted wire pair and the insulated wire cores is high-quality copper free wire or high-quality tinned copper wire.
The present invention is rational in infrastructure simple, manufactures easily, and cost is low; Cable smooth in appearance rounding, serviceability is good, adopts nanometer scale ceramics silicon rubber new material; Utilization phase-splitting, total composite shielding structure; Guaranteed that cable has fire protecting performance, bending property, good insulation preformance, puncture voltage is high, heat-resistance index is big, tension anti-mechanical damage, anti-strong electromagnetic and strong electrostatic interference, had low electric capacity, low inductance and every pair of core and can have characteristics such as high-frequency signal transmission, in addition under the situation of breaking out of fire; Cable has high fireproof oxygen barrier; Nontoxic non smoke, light transmittance be up to 85%, helps that personnel withdraw evacuation, the fire fighter puts out a fire and rescues trapped personnel and property, reduces loss as far as possible.According to international bunchy combustion experiment standard IEC 60332-3:1992, reach the requirement of category-A bunchy combustion experiment set quota, satisfy the safe in utilization of every profession and trade industrial automation system, excellent popularization using value and vast market prospect are arranged.
