Abstract
The utility model discloses a halogen-free low-smoke flame-retardant signal cable for detection, control and computer. The halogen-free low-smoke flame-retardant signal cable comprises seven conductor groups in regular hexagon arrangement, wherein the seven conductor groups consist of two stranded cable conductors covered by an insulating layer, respectively; the cable conductor has a sectional area of 0.75 to 0.785mm<2>; a single shield layer wraps the two stranded cable conductors; the seven conductor groups having the two stranded cable conductors covered by the single shield layer are sequentially covered by, from inside to outside, a cladding layer, a shield layer and an outer sheath layer; the single shielding layer wrapping the main conductor group at the center of the seven conductor groups is a semiconductor shield layer; and a drainage wire is arranged outside each single shield layer. The semiconductor shield layer wrapping the center main conductor group has a stable magnetic field so as to ensure stable signal transmission; and the drainage wires can improve the interference resistance of the halogen-free low-smoke flame-retardant signal cable provided by the utility model. In addition, the cable conductor is technically improved on the sectional area.
Description
Technical field
The utility model relates generally to field of cables, relates in particular to a kind of detection, control and computer and uses the LSOH anti-flaming signal cable.
Background technology
Wires and cables industry is the second largest industry that China is only second to automobile industry, and product variety satisfies rate and domestic market occupation rate all above 90%.Worldwide, the Chinese electric wire gross output value has surpassed the U.S., becomes first in the world electric wire producing country.Be accompanied by Chinese wires and cables industry high speed development, creation of new enterprise quantity constantly rises, and industry overall technology level is largely increased.China's economic growth continuously and healthily; For cable products provides the huge market space, the temptation that Chinese market is strong makes the world all focus on Chinese market to sight; Reforming and opening up to the outside world short decades, the formed huge production capacity of Chinese cable manufacturing industry lets the world regard with special esteem.Along with the continuous expansion of industry sizes such as China Power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire already also has huge development potentiality.
The application of electronic computer, instrument and meter is universal day by day, and people's awareness of safety constantly strengthens, and the performance and the environmental requirement of the cable supporting with it also improved constantly.Existing computer and instrument are high temperature resistant not high with fire resistance with cable, and the security reliability of cable is low under fire condition, and shielding properties and interference free performance are not high, are not suitable for as densely populated and higher to device security reliability requirement place.
Therefore, it is good to be badly in need of a kind of high temperature resistant, anti-flammability, shielding, anti-interference, and safe detection, control and computer are used the LSOH anti-flaming signal cable.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, to provide a kind of detection, control and computer to use the LSOH anti-flaming signal cable.
The utility model is realized through following technical scheme:
Detection, control and computer are used the LSOH anti-flaming signal cable; Include seven conductor groups; Described seven conductor groups are regular hexagon and arrange; It is characterized in that: described seven conductor groups constitute by two cable conductors that are enclosed with insulating barrier are stranded respectively, and the sectional area of cable conductor is 0.75-0.785 mm
2Two cable conductor outsides after stranded are enclosed with individually shielded layer; Seven conductor groups outside with two cable conductors after the independent screen of parcel stranded is enclosed with belting layer, screen, external sheath layer from inside to outside successively; The individually shielded layer of the leading body group outerwrap at the center in described seven conductor groups is a semiconductive shielding layer, and each individually shielded layer is outside equipped with drainage thread.
Described insulating barrier adopts crosslinked polyethylene.
Described screen is that the copper wire braiding forms.
Described external sheath layer adopts polyolefin.
Described cable conductor adopts bare copper wire.
The utility model has the advantages that:
The utility model is simple in structure, manufacturing is convenient; Its resistance to wear, anti-flammability, water proofing property improve greatly; Around the semiconductive shielding layer of the leading body group outerwrap at center stable magnetic field is arranged, make stable signal transmission, drainage thread improve the anti-interference of the utility model; In addition, the sectional area to cable conductor has carried out technologic improvement.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1; Detection, control and computer are used the LSOH anti-flaming signal cable, include seven conductor groups, and seven conductor groups are regular hexagon and arrange; Seven conductor groups constitute by two cable conductors that are enclosed with insulating barrier 21 are stranded respectively, and the sectional area of cable conductor 1 is 0.75-0.785 mm
2Two cable conductor 1 outsides after stranded are enclosed with individually shielded layer 3; Seven conductor groups outside with two cable conductors 1 after the independent screen 3 of parcel stranded is enclosed with belting layer 4, screen 5, external sheath layer 6 from inside to outside successively; The individually shielded layer 3 of the leading body group outerwrap at the center in seven conductor groups be semiconductive shielding layer 3a, and each individually shielded layer 3 is outside equipped with drainage thread 7.
