Description
Technical field
The present invention relates to a kind of cable, and in particular to unleaded polyvinyl chloride insulation environment-friendly cable.
Background technology
Shield is in a point protective metal shell in power cable（Such as what steel of aluminium, lead）And non metallic sheath（Such as what plastics of rubber）.Metal
Sheath is used for oil-impregnated paper insulation cable, and rubber, plastic sheath are used for rubber and plastic class insulated cable.But rubber, plastic sheath
Power cable is using less, and steel sheath is mainly used in EHV XLPE power cable, and power cable inner sheath has been manufactured with lead very
Long history, is due to that lead sheath has the advantages that complete impermeability, can reliably prevent the intrusion of moisture and moisture, close
Sealing property is good, and also has the advantages that corrosion resistance and good, good toughness do not influence the flexibility of cable, while the resource of lead lacks
Weary, reserves are less in the earth's crust, and lead is that noxious material is easily detrimental to health pollution environment, and lead is relatively denser,
Make cable heavy, made troubles to manufacture, transport and installation.Therefore it is more and more to use unleaded polyvinyl chloride cable, however,
There is heat resistant fire-proof poor-performing and the not enough defect of intensity in existing unleaded polyvinyl chloride cable.With expanding economy,
Building develops to high level, and the increase of various electric utilities and accelerating development for power grid construction, disaster hidden-trouble also increase therewith,
Add the danger level for occurring fire.According to statistics, in many fire incidents, the fire as caused by electric wiring is up to 80%.Fire
Calamity, which is not only resulted in, can also produce a large amount of poisonous and hazardous gases in substantial amounts of economic loss, cable combustion process, cause environment
Pollution.If cable fire poor-performing and can not provide enough mechanical resistant external impacts in a fire, easy cable is lost
Fire resistance, it is impossible to realize normal power supply ability.
The content of the invention
The technical problems to be solved by the invention are that existing unleaded polyvinyl chloride cable fire resistance and intensity are poor,
Cable fire poor-performing and enough mechanical resistant external impacts can not be provided in a fire, then easy cable loses fire resistance
Can, it is impossible to realize normal power supply ability, it is therefore intended that unleaded polyvinyl chloride insulation environment-friendly cable is provided, be conducive to improving cable
Fire resistance and resistance to mechanical impact strength, it is ensured that cable normal power supply ability.
The present invention is achieved through the following technical solutions：
Unleaded polyvinyl chloride insulation environment-friendly cable, including four phase conductors, the conductor are externally provided with insulating barrier, four phase conductor
In annular shape distribution, insulating barrier outer cable radially be sequentially provided with from inside to outside packed layer, the first heat-resistant layer, inner sheath,
Water blocking layer, the second heat-resistant layer and oversheath；The packed layer is irradiated using Halogen and handed over using the loose gentry's filling of asbestos, the inner sheath
Join polyolefin flame-retardant layer, the oversheath uses unleaded polyvinyl chloride layer；Steel wire is uniformly placed with outside the oversheath, it is described
With cable axis in the same direction, the steel wire is anticorrosion coating steel wire for the axial direction of steel wire.
The present invention passes sequentially through the second heat-resistant layer, the first heat-resistant layer and packed layer to cable inner sheath, insulating barrier and conductor
Deng heatproof flameproof protection is carried out, by some steel wires of uniformly being arranged outside oversheath, be conducive to strengthening the resistance to mechanical impact of cable
Intensity.
Preferably, the diameter of the steel wire be less than the oversheath ring set thickness, and the steel wire section at least
Half insertion is set in oversheath.
By the way that steel wire is located on oversheath using embedded, the contact area of increase steel wire and external sheath layer, both favorably
In strengthening the mounting stability of steel wire, while may advantageously facilitate cable radiating.
Preferably, the circular center of the conductor is provided with strengthening core, and the strengthening core is bend resistance carbon steel wire.
Carbon steel wire strengthening core is set to be conducive to increasing the bend resistance intensity of wire by the ring center arranged in cylinder,
Each protective layer of cable is protected not by mechanical deflection damage.
Preferably, first heat-resistant layer uses heatproof coated ceramic material layer.
By using heatproof coated ceramic material layer as the first heat-resistant layer, not only improve and provide heat-blocking action for conductor,
Be conducive to strengthening the intensity of cable simultaneously.
Preferably, second heat-resistant layer is using silicone rubber insulation material layer.
By using silicone rubber insulation material layer as the second heat-resistant layer, it is mainly used in providing heatproof protection work for inner sheath
With while there is certain cushioning effect.
Preferably, the water blocking layer is using polyacrylate swelling fiber coating nylon layer.
By the protective action that actively absorbs water, prevent the inner restrictive coating moisture absorption from causing decreasing insulating, influence cable point performance.
The present invention compared with prior art, has the following advantages and advantages：
1st, unleaded polyvinyl chloride insulation environment-friendly cable of the invention, the present invention pass sequentially through the second heat-resistant layer, the first heat-resistant layer and
Packed layer carries out heatproof flameproof protection to cable inner sheath, insulating barrier and conductor etc., some by uniformly being arranged outside oversheath
Steel wire, is conducive to strengthening the resistance to mechanical impact strength of cable；
2nd, unleaded polyvinyl chloride insulation environment-friendly cable of the invention, by the way that steel wire is located on oversheath using embedded, increase
The contact area of steel wire and external sheath layer, not only improves the mounting stability for strengthening steel wire, while may advantageously facilitate cable radiating.
