Description
technical field:
The utility model relates to electric wire, relates in particular to a kind of fire-resistant and sound absorption-type 485 data-signal transmission cables.
background technology:
Along with the high speed development of optical communication technique, the backbone network of China's wire net and interoffice trunk generally use optical cable, and optical fiber enters Access Network has become inexorable trend.But fiber cable laying expense is too high, joint expense and terminal light-electric conversion charges costliness, therefore, in a very long time before fiberize is universal, the subscribers feeder of Access Network will be taking metal cables as main.
Metal cables mainly comprises three kinds of all-plastic cable, coaxial cable and data cables.Wherein, data cable is the transmission medium of current more satisfactory broadband access network, and it has advantages of, and manufacturing cost is lower, simple in structure, expandability is good, be convenient to network upgrade, is mainly used in building wiring, community computer generalization wiring etc.
Can adopt common twisted-pair feeder in low speed, short distance, glitch-free occasion, otherwise, in the time of high speed, the transmission of long line, must adopt the RS485 data-signal of impedance matching (being generally 120 Ω) to transmit special cable, fire resistance and the sound absorption qualities of data-signal transmission cable are in the market poor, make cable useful life shorten and signals transmission in stability can not be guaranteed.
utility model content:
In order to make up prior art problem; the purpose of this utility model is to provide a kind of fire-resistant and sound absorption-type 485 data-signal transmission cables; structural design novelty; manufacturing cost is relatively low; there is higher fire resistance and sound-absorbing effect; can effectively protect cable core to stablize the lasting work of carrying out, ensure the transmission of data-signal.
The technical solution of the utility model is as follows:
Fire-resistant and sound absorption-type 485 data-signal transmission cables, it is characterized in that: comprise multiple core groups, each core group equal two is thoroughly done away with edge data-signal control core and the stranded formation of non-metal reinforcement member, every eradication edge data-signal control core includes the aluminium foil lapped shielding layer that conductor and outside thereof are coated successively, polyacrylic resin coat, polyester belt lapping layer, low carbon macromolecule refractory thermal insulator layer forms, each core group outside is coated with proof copper-wire braided sub-shield successively, composite fire lapping layer, the mutual stranded bunchy of multiple core groups forms cable core, cable core is coated with the wrapped total screen of aluminium foil outward successively, polyester belt lapping layer, the heat insulation belt of ceramic fibre, fire-retardant oxygen barrier lining, acoustical cotton band lapping layer, LSZH external sheath layer.
Described fire-resistant and sound absorption-type 485 data-signal transmission cables, is characterized in that: described composite fire lapping layer adopts fire-resistant isinglass belt, rock wool belt, the wrapped formation of the stacked pressure of fire-resistant isinglass belt three, and thickness is generally 0.04 ~ 0.16mm.
