Description

Low smoke and zero halogen anti-ultraviolet frequency-changing cable
Technical field
The present invention relates to a kind of frequency-changing cable, especially a kind of low smoke and zero halogen anti-ultraviolet frequency-changing cable.
Background technology
Domestic existing frequency-changing cable is generally common quad, does not possess the ability of electromagnetism interference;And structural stability is relatively poor, the injury to cable such as Mus, ant after cable laying, reduce security performance and the service life of cable.
Summary of the invention
The technical problem to be solved is to provide a kind of low smoke and zero halogen anti-ultraviolet frequency-changing cable, external electromagnetic can be solved dry and noise problem, outside electromagnetic interference can be shielded, lower frequency conversion motor noise, strengthen the proof voltage impact of cable, bending property and resistance to environment capacity.
For solving above-mentioned technical problem; the technical solution adopted in the present invention is: a kind of low smoke and zero halogen anti-ultraviolet frequency-changing cable; master core and the protection core being positioned at master core gap form stranding; the PP rope that stranding gap is filled forms cable core, is enclosed with the first lapping layer, proof copper-wire braided screen layer, the second lapping layer, copper strip shielding layer, the 3rd lapping layer and low smoke and zero halogen external sheath layer outside cable core successively.
Master core is made up of master core conductor and the master core insulating barrier being wrapped in outside master core conductor.
Protection core is made up of protective wire core conductor and the protective wire core insulation layer being wrapped in outside protective wire core conductor.
Second lapping layer forms by alkali-free glass strap and around the polyester band wrapped in outside alkali-free glass cloth band.
3rd lapping layer is inhibiting tape.
The quantity of master core is three, and the quantity of protection core is three.
Screen layer is proof copper-wire braided screen layer and the double-layer shielding structure of copper strips lapped shielding layer.
Low smoke and zero halogen anti-ultraviolet frequency-changing cable provided by the invention, has the beneficial effect that:
1, proof copper-wire braided screen layer and the wrapped double-layer shielding structure of copper strip shielding ply are adopted, transfer impedance is low, elimination outside electromagnetic interference is effective, the design coordinating the second lapping layer and the 3rd lapping layer has simultaneously worked as attenuating frequency conversion motor noise, adopt the 6th class conductor structure, make the good bending property that cable possesses, adopt the effect of the stronger resistance to environment capacity that low smoke and zero halogen anti-ultraviolet sheath makes cable possess.
2, the quantity of master core is three, the cable core structure of " 3+3 " that quantity is three of protection core, and stable, compact, it is strong that resistance to converter produces pulse voltage impact.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the production technological process of the present invention.
Detailed description of the invention
As shown in Figure 1; a kind of low smoke and zero halogen anti-ultraviolet frequency-changing cable; master core and the protection core being positioned at master core gap form stranding; the PP rope 5 formation cable core that stranding gap is filled, is enclosed with the first lapping layer 6, proof copper-wire braided screen layer the 7, second lapping layer 8, copper strip shielding layer the 9, the 3rd lapping layer 10 and low smoke and zero halogen external sheath layer 11 successively outside cable core.
Master core is made up of master core conductor 1 and the master core insulating barrier 2 being wrapped in outside master core conductor 1.
Protection core is made up of protective wire core conductor 3 and the protective wire core insulation layer 4 being wrapped in outside protective wire core conductor 3.
Second lapping layer 8 forms by alkali-free glass strap and around the polyester band wrapped in outside alkali-free glass cloth band.
3rd lapping layer 10 is inhibiting tape.
The quantity of master core is three, and the quantity of protection core is three.
The technological process of production of the present invention is as in figure 2 it is shown, production essentials is as follows:
1, master core conductor 1 and protective wire core conductor 3: adopt and meet the 6th class conductor of GB/T3956-2008, protective wire core conductor divide equally three stranded.
2, master core insulating barrier 2 and protective wire core insulation layer 4: adopt cross-linked polyethylene insulating material;Performance meets the regulation of GB/T12706.1-2008.
3, stranding: stranding lay ratio is 20~25 times, protection core is arranged in master core gap, and all the other gaps adopt non-absorbent material PP gasket for packing 5 to fill rounding.After stranding, overlap is around polyester band of double-baging.
4, shielding: adopting proof copper-wire braided screen layer and copper strips overlap lapped shielding layer composition, count is not less than 80%.The overlapping wrapped one layer of alkali-free glass strap of difference and a strata fat band after the braiding of proof copper-wire braided screen layer, the outer wrapped one layer of inhibiting tape of copper strip shielding layer.
5, low smoke and zero halogen external sheath layer 11: adopt and add by the polyolefine material of the termite-resistant rodent-resistant repellant extracted in plant;Jacket thickness by GB/T12706.1-2008 appendix A computational methods determine.
