Abstract
The utility model relates to a combined type cable, including the inner sheath, inner sheath inside is provided with the netted stopping of polypropylene, is provided with the fire -retardant area of oval -shaped low smoke and zero halogen in the netted stopping of polypropylene, and the fire -retardant in -band of low smoke and zero halogen is provided with glass fiber rope stopping, sets up in the glass fiber rope stopping to have or not the low fire -retardant EP rubbers insulating layer of cigarette of bittern, does not have the interior parcel of the steamed low fire -retardant EP rubbers insulating layer of cigarette and has the polyester area, and the polyester in -band is equipped with the conductor, the inner sheath outside is provided with the weaving layer, and the weaving layer outside is provided with fire -retardant water blocking layer, and fire -retardant water blocking layer skin is provided with the oversheath layer. The utility model has the advantages of soft, to bear the electric current big, can obviously improve resistant electric stability and operating temperature, have high temperature resistant, corrosion -resistant, small, high insulating in addition and can, not have a performance such as steamed low cigarette. This cable has the compliance ability of high strength, need not to adopt any metal sheath alright its tensile of reinforcing, shocks resistance and the abrasion resistance ability.
Description
Technical field
The utility model relates to a kind of Combined cable, belongs to field of cable technology.
Background technology
At present, cable is extensive use just, the most function singleness of these cables, particularly in waterproof, fire prevention, and is short of to some extent in acid and alkali-resistance etc.And when fire incident occurs, how to leave the sufficient time ensure people safe escape, minimizing accident loss, ensure that line security energising, signal are unimpeded, how improving the fire safety grade of key project, important place, special dimension etc., is the diligent pursuit of cable industry research staff.Generally all there is following problem and difficult point in now general functional cable: 1. installs complexity; 2. transition joint of constructing is many; 3. bending property is poor; 4. manufacturing equipment costliness and complex process; 5. the pressure drop of fire condition lower end is large; When 6. moving bending, weld seam is easy to crack; 7. the wasting of resources is large, cost is high; 8. electric property is unstable, to puncture rate high; 9. thick, the Heavy Weight of external diameter etc.These factors have had a strong impact on the promotion and application of cable in prior art.
Utility model content
The purpose of this utility model is to provide a kind of Combined cable, generally can more effectively play fireproofing of cable water-proof function, more contributes to popularization and the use of cable.
To achieve these goals, the technical solution of the utility model is as follows.
A kind of Combined cable, comprise inner sheath, inner sheath inside is provided with polypropylene mesh inserts, oval low-smoke non-halogen flame-retardant band is provided with in polypropylene mesh inserts, glass cord inserts is provided with in low-smoke non-halogen flame-retardant band, be provided with the ethylene propylene rubber insulated layer of LSOH anti-flaming in glass cord inserts, be enclosed with polyester belt in the ethylene propylene rubber insulated layer of LSOH anti-flaming, in polyester belt, be provided with conductor; Inner sheath arranged outside has braid, and braid arranged outside has fire-retardant water blocking layer, and fire-retardant water blocking layer skin is provided with external sheath layer.
Further, conductor is anaerobic fine copper compact conductor or single solid conductors.
Further, the low cigarette protective cover material of inner sheath high-flame-retardanthalogen-free halogen-free.
Further, fire-retardant water blocking layer adopts the high flame retardant composite band material that blocks water to process.
Further, external sheath layer is formed by high flame retardant, the plastic processing of acid and alkali-resistance polyvinyl chloride rubber-plastic elastomer.
The beneficial effect of this utility model is: the utility model cable is well-regulated by the soft round conductor that some diameters are identical, the layering of concentric type is twisted system and formed, and has the advantages such as softness, loaded current are large.Fire-retardant water blocking layer adopts the high flame retardant composite band material that blocks water to process, external sheath layer is formed by high flame retardant, the plastic processing of acid and alkali-resistance polyvinyl chloride rubber-plastic elastomer, resistance to electrical stability and working temperature can be significantly improved, there is high temperature resistant, corrosion-resistant, the performance such as volume is little, high insulating property, low smoke, zero halogen in addition.This cable has high strength flexible performance, adopt soft round copper wire stranded conductor with through knitting device high-strength composite flexible fibrous material, without the need to adopting any metal sheath just can strengthen its tension, shock resistance and abrasion resistance properties, and be applicable to the occasion being used in frequent mobile towing.Improve the structural design of bending property, make it have the bending radius being less than similar common cable.This product mounting and installation, continue and install just the same with conventional power cable design, without the need to special annex and specific purpose tool.
