At least one stranded wire pair and at least one insulated core are stranded into the cable core; a split-phase composite shielding layer and a split-phase wrapping layer are arranged at the exterior of the wire pair; a cabling wrapping layer, a high-fireproofing nanometer ceramic silicon rubber inner sheath, a total composite shielding layer, a wrapping isolation layer and a high-fireproofing nanometer ceramic silicon rubber outer sheath are sequentially arranged at the exterior of the cable core; and high-fireproofing halogen-free fillers are arranged in gaps among cable cores. The cable is good in electric property and excellent in fire resistance and anti-electromagnetic interference capacity, and can better meet the operating requirements.
Description
Technical field
The utility model relates to a kind of fire prevention high flexibility data cable, belongs 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, by 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, the intelligent machine field device, automatically operate and Data Control, be included in and realize the peer-to-peer information transmission on the same cable, the teleprogram design, fault is got rid of and I/O upgrades and the interlocking of PLC processor, painting workshop and assembly line, water/waste water treatment, food processing, specific (special) requirements occasion and controls such as pharmacy and classification conveyer, security protection, vehicle automobile automatic assembly line, instrument, fields such as 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 energy 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 purpose of this utility model is exactly for adapting to the demand in market, overcome the deficiency that existing normal cable exists, a kind of electrical property that makes cable is provided, transmission performance, interference free performance and fire protecting performance are superior, the data of cable, fire prevention, Halogen, nontoxic, can compare favourably with external like product with every performance index such as smokeless, and have high temperature resistant, seawater corrosion resistance, the insulation property height, fire line is good, the puncture voltage height, heat-resistance index is big, tension is prevented mechanical damage, anti-electromagnetic interference and anti-inside and outside electrostatic interference superior performance, and low electric capacity, low inductance, nontoxic non smoke, the fire prevention high flexibility data cable that light transmittance is high.
The purpose of this utility model is achieved through the following technical solutions, and the insulated wire cores by a pair of twisted wire pair and at least one core is twisted into cable core at least, and 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.
