Abstract

The utility model discloses an aluminum alloy fire-proof power cable composed of conductors, insulating layers, a filling layer, a low-smoke zero-halogen wrapping tape layer, and an outer sheath layer. A cable core is formed by twisting a plurality of insulated wire cores. A filling layer is arranged in gaps of the cable core. Each of the insulated wire cores is formed by one conductor and one insulating layer from inside to outside. The low-smoke zero-halogen wrapping tape layer and the outer sheath layer are sequentially wrapped outside the cable core and the filling layer. The aluminum alloy fire-proof power cable of the utility model has high environmental protection performance and high fire-proof performance, and generates relatively little smoke and no harmful hydracid substance during combustion. In brief, the aluminum alloy fire-proof power cable is a novel product with high environmental protection performance and high fire-proof performance and has a broad market prospect.

Description

A kind of aluminium alloy fire-resisting cable

Technical field

The utility model relates to field of cables, is specifically related to a kind of aluminium alloy fire-resisting cable.

Background technology

The cable of selling in the market be all generally with copper core and aluminium core as conductor, modal is exactly the conductor as cable with the copper core, also have some with the aluminium core conductor as cable, this is conductivity, thermal conductivity and good processability because of copper and aluminium.Along with social development, the demand of electric wire increases day by day, and copper and aluminium are main materials in the electric wire the inside, and its weight accounts for 75% left and right of electric wire, and what have even reaches more than 90%.Electric wire is used copper and aluminium as conductor material in a large number in recent years, and copper and aluminium are non-renewable resources, and electric wire can not use copper and aluminium as conductor material always, is badly in need of wanting new electric wire and cable conductor material replace copper and aluminium.Aluminium alloy density is low, but strength ratio is higher, approaches or surpasses the high-quality steel, plasticity is good, can be processed into various section bars, has good conductivity, thermal conductivity and corrosion stability, its cost is low again simultaneously, in Aeronautics and Astronautics, automobile, machine-building, boats and ships and chemical industry, widely applies.The fine aluminium conductor that 8000 series alloys conductors are different from the past, through a series of technology, by add iron, magnesium and some other metallic elements in fine aluminium after, its electric property and fine aluminium are substantially suitable, mechanical performance is significantly improved, slightly all approach and even surpassed copper conductor in creep resistant, pliability, corrosion resistance and surrender, also started in recent years to be widely used on electric wire.

Summary of the invention

For overcoming the defect of prior art, the purpose of this utility model is to provide a kind of cost advantage that both possessed, and possesses again the aluminium alloy fire-resisting cable of high-environmental performance and high fire resistance.

The utility model technical solution problem adopts following technical scheme: a kind of aluminium alloy fire-resisting cable, it is comprised of conductor, insulating barrier, packed layer, low smoke and zero halogen belting layer and outer jacket, the stranded formation cable cores of edge core that thoroughly do away with more, be provided with packed layer in the cable core gap, the insulated wire cores from-inner-to-outer consists of conductor and insulating barrier, and cable core and packed layer are coated with low smoke and zero halogen belting layer and outer jacket outward successively.

Described conductor is 8000 series alloys materials.

Described insulating barrier is ceramic silicon rubber insulation material.

Described outer jacket is ceramic silicone rubber jacket material.

The beneficial effects of the utility model are embodied in: conductor adopts the aluminium alloy compacted stranded conductor of the 2nd class, can prevent the corrosion of moisture content and other harmful substance; Insulating material adopts ceramic silicon rubber to make, this material is a kind of novel polymer composite, be different from other macromolecular materials be this material have Halogen, nontoxic, tasteless, human body, natural environment are had no adverse effects, flue gas after burning is very little, there is no smoke toxicity, flue gas is also harmless to human body.Sheath material also adopts ceramic silicon rubber to make, doing restrictive coating with it can be in the situation that breaking out of fire, guarantee the unimpeded of electric power, communication line, loading under rated voltage, the not short circuit of 90-180min in the situation that 650-1300 ℃ of flame ablation worked, open circuit; Ceramic silicon rubber insulation and restrictive coating make cable have high fire resistance, and its fire resistance, far beyond the fire-resistant burning test requirement of standard GB/T/T 19666-2005 regulation, has guaranteed the fail safe that cable is used under fire condition.The utility model product all material all adopts halogen-free low-smoke flame retardant material, and while making this cable fire, smoke density is very low, and non-corrosiveness gas is overflowed, and does not also produce harmful hydracid material, can be widely used in the more concentrated place of some personnel.In a word, this utility model product is a kind of new product with environmental-protecting performance and high fire resistance, and wide market prospects are arranged.

The accompanying drawing explanation

Fig. 1 is structural representation of the present utility model.

In figure: 1, conductor; 2, insulating barrier; 3, packed layer; 4, low smoke and zero halogen belting layer; 5, outer jacket.

Embodiment

As shown in Figure 1, a kind of aluminium alloy fire-resisting cable, it is comprised of conductor 1, insulating barrier 2, packed layer 3, low smoke and zero halogen belting layer 4 and outer jacket 5, the stranded formation cable cores of edge core that thoroughly do away with more, be provided with packed layer 3 in the cable core gap, the insulated wire cores from-inner-to-outer consists of conductor 1 and insulating barrier 2, outer low smoke and zero halogen belting layer 4 and the outer jacket 5 of being coated with successively of cable core and packed layer 3.
