Description
Technical field
The utility model relates to a kind of cable, particularly a kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath.
Background technology
In the various architectural engineerings at home, the electric wire that is used for fixing wiring is used very extensive.Electric wire both can be applicable to the important engineering that there is environmental requirement in top-grade building, dwelling house, office building, large halls and guest houses, subway, tunnel etc., again can with environmental protection electronic equipment, the supporting use of household electrical appliance, relate to huge numbers of families.This class electric wire at present mainly is to be the BLV of representative with IEC in the world, it is the portioned product that is comprised among standard GB 5023-2008 and the mechanical industry standard JB8734-1998, the insulating barrier of cable mostly adopts the insulating material of Halogen, one meets naked light will propagating combustion, and produce a large amount of smog and the very strong hydrogen halide of corrosivity, form " secondary disaster ", in case breaking out of fire in the building, both entail dangers to life also can serious environment pollution.
The utility model content
The purpose of this utility model is that a kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath will be provided, and efficiently solves the electric wire easy firing, the burning that exist in the prior art and can produce problems such as toxic gas contaminated environment.
The utility model relates to a kind of power cable with crosslinked polyethylene insulating layer and thermoplastic elastomer sheath, comprise the cable inner core and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core and insulating barrier from inside to outside, described cable outer layer inside is followed successively by fire-retardant band and sheath from inside to outside, is provided with the flame retardant type filler between described cable inner core and the cable outer layer.The number of the cable inner core in the described cable outer layer is one or more.The material of described wire core is a high purity oxygen free copper.Described conductor wire core is the many soft single lines of round copper that twist together.The soft single line of described round copper is that naked round annealed copper wire or overlay coating are the single round copper wire of tin.The material of described insulating barrier is a Halogen cross-linked type polyethylene insulating material.Described flame retardant type filler is the glass fibre gasket for packing.Described fire-retardant band is a high flame retardant alkali-free glass strap.The material of described sheath is a thermoplastic elastomer (TPE) TPE material.
The utlity model has water-fast, fire-resistant, chemicals-resistant, high-low temperature resistant, flexibility are good, characteristics such as low smoke and zero halogen meet the ROHS of European Union standard, can be widely used in military project, boats and ships, nuclear power, wind energy, railroad track traffic, the contour end line cable of magnetic suspension field.
Description of drawings
Accompanying drawing 1 is the cross-sectional view when the utlity model has four cable inner cores.
Below in conjunction with accompanying drawing the utility model is described.
Embodiment
Comprise the cable inner core among the figure and wrap in the outer cable outer layer of cable inner core, described cable inner core inside is followed successively by conductor wire core 1 and insulating barrier 2 from inside to outside, described cable outer layer inside is followed successively by fire-retardant band 3 and sheath 4 from inside to outside, is provided with flame retardant type filler 5 between described cable inner core and the cable outer layer.
The number of the cable inner core in the described cable outer layer is one or more.The material of described conductor wire core is a high purity oxygen free copper.Described conductor wire core is for twisting together the many soft single lines of round copper.The soft single line of described round copper is that naked round annealed copper wire or overlay coating are the single round copper wire of tin.The cross section of conductor wire core of the present utility model is circular, and geometry is fixed, and stability is high, but very little to the curvature influence of cable.The physical strength of conductor wire core is lower, and is soft, and cable is flexible.
The material of described insulating barrier is a Halogen cross-linked type polyethylene insulating material, is a kind of thermoplastic low-smoke halide-free CABLE MATERIALS.The extrusion modling of Halogen crosslinked polyethylene insulation material, by crosslinked special processing, change polyethylene line style molecular structure into solid netted molecular structure, improved the electric property of product greatly, physical property, mechanical performance, ageing resistace and adaptive capacity to environment and other properties, not only high temperature resistant and have the advantages that not prolong the combustion and can not produce the very strong hydrogen halide of corrosivity.
Described flame retardant type filler is the glass fibre gasket for packing, and resistance to elevated temperatures is good, and is nonflammable.Described fire-retardant band is a high flame retardant alkali-free glass strap.Flame retardant type filler and fire-retardant band isolated insulation layer and cable outer layer are in case mutual bonding and influence the machinery, physics, electrical property etc. of cable between them.Fire-retardant band adopts aluminium borosilicate glass to take out system fibrage and forms, and its alkali metal thing is not more than 0.5%, directly becomes band limit with lock, non-frangibility, character softness, wrapped smooth, stretching resistance extra-heavy behind the finished product.Fire-retardant band can not burn below 900 ℃ in temperature after meeting naked light, can stop flame to pass, and the protection insulating barrier is not burnt, and the smog that is discharged during burning is few, reduces the so harmful degree of fire greatly.When cable is burnt; flame retardant type filler and fire-retardant band can absorb a large amount of heats; and the shell isolated air of formation carbon; hinder the supply of oxygen and flowing of fuel gas; the protection insulating barrier is avoided burning; prevent that cable from further burning, make the loss of fire be unlikely further extension.
The material of described sheath is a thermoplastic elastomer (TPE) TPE material.Thermoplastic elastomer (TPE) TPE material is the synthetic material of the physical and mechanical properties such as high resiliency of a kind of repetition processability that has thermoplastics concurrently and rubber, has simultaneously excellent reclaiming again, waterproof, softness, anti-chemical (acid and alkali-resistance, anti-ozone, oil resistant etc.), heatproof-65 ℃ is a kind of halogen-free environmental material.Cable does not just discharge pernicious gas and smog in when burning like this, and unlikely causing " secondary disaster " is safe, environment friendly and pollution-free, can be suitable for various specific occasions and lay, and effectively prolongs product useful life.
