Description
Technical field
The utility model belongs to the cable technology field, is specifically related to a kind of mining flame-retardant induction cable.
Background technology
For a long time, the selection of people to low-voltage cable for building, normally take copper as main.Think copper conductor on electric property and the degree of reliability all higher than other conductors, be the only selection as cable material.But copper is as tellurian a kind of scarce resource, and especially in our country, ore reserve are very limited, a large amount of dependence on import of Copper Ores.And China's bauxite resource is very abundant, account for 12% of world's gross reserves, research and development and application aluminium alloy cable, realization with aluminium for copper, it is the development trend of China's cable industry, because mechanical performance and the corrosion resistance of common aluminium cable are poor, so the aluminium cable in China every year accounts for 3% of national cable total amount, make aluminium cable never obtain penetration and promotion.
Along with the increase of mobile electrical plant capacity, should provide high pressure 6/10KV level flame-proof rubber cover flexible cable supporting with it.The traditional cable structure is three main cores and a ground wire, and because the ground wire cross section is little, stranded arrangement is asymmetric, and often cable is frequently mobile crooked, causes ground wire easily to rupture, main core insulation easy damaged, and useful life is short.It is the material of base-material that the insulating barrier of existing cable adopts the higher ethylene-propylene rubber of insulation property, and it is the material of base-material that sheath adopts lower-cost haloflex.Owing to using traditional compounding ingredient, make cable with the strong impulse smell, while particularly burning, discharge the acetophenone toxic gas, jeopardize personal safety, contaminated environment.Chinese patent CN201220585208.0 discloses a kind of ac rated voltage 6/10KV and following mine mobile device aluminium core flame-proof rubber cover flexible cable of being applicable to, comprise four main cores and a ground wire, main core be by main core aluminium alloy conductor wrap up conductor shield from the inside to surface, braid forms, ground wire consists of ground wire aluminium alloy conductor wrap insulate layer, four described main cores are around the symmetrical stranded formation cable core of ground wire, and the cable core skin is enclosed with belting layer and fire retardant jacket.The made cable of this technical scheme has high voltage withstanding, long service life, odorless, fire-retardant characteristics.But in a single day have an obviously deficiency, tensile property and resistance to elevated temperatures are not good yet, easily break down, and break down, be difficult to detect timely and accurately the cable damaged location, are difficult for changing and maintenance.
The utility model content
The purpose of this utility model is to provide a kind of mining flame-retardant induction cable of new construction, and by architecture advances, not only fire resistance is better, tensile property is better, and, when the faults such as the disconnected core of cable generation, the cable damaged location can be detected timely and accurately, easy to replace and maintain.
For realizing this purpose, the technical solution of the utility model is: a kind of mining flame-retardant induction cable, comprise four main cores and a ground wire, main core be by main core aluminium alloy conductor wrap up conductor shield from the inside to surface, braid forms, ground wire consists of ground wire aluminium alloy conductor wrap insulate layer, four described main cores are around the symmetrical stranded formation cable core of ground wire, the cable core skin is enclosed with belting layer and flame retardant sheath layer, between described belting layer and flame retardant sheath layer, along the vertical aspect of cable, the sensing fiber is set.
As preferably, described conductor is by multiply nickel plating soft copper silk stranded forming in the same way.
As preferably, described flame retardant sheath layer is comprised of carbon fiber shielding internal layer and the fireproof silicone rubber external sheath layer that is positioned at its outer surface, between described shielding internal layer and external sheath layer, is provided with a terylene woven reinforced layer that is formed by some dacron threads braidings.
As preferably, described terylene woven reinforced layer is coated with by the wrapped heat insulation reinforced layer that forms of some high temperature resistant stainless steel alloy silk ribbons.
With respect to prior art, it is core that the utility model adopts the stranded in the same way conductor that forms of multiply nickel plating soft copper silk on the one hand, easily crooked, the adaptability of environment is high, nano-scale carbon fibrillatable fireproof silicone rubber material outer jacket has improved the mechanical strength of cable, waterproof, protection against the tide, anti-chemical corrosivity strengthen, and have extended the useful life of cable.Built-in sensing fiber in composite shielding layer, can monitor accurately to cable on the other hand, when sensing fibrous fracture, can clearly find fracture position, tries to avert accidents, and uses safer.The heat insulation reinforced layer that arranges simultaneously plays a very good protection when the breaking out of fire to cable.

Embodiment
In conjunction with the embodiments the utility model is further illustrated with reference to the accompanying drawings.
As shown in Figure 1, a kind of mining flame-retardant induction cable, comprise four main cores 3 and a ground wire 7, main core 3 be by main core aluminium alloy conductor 6 wrap up from the inside to surface conductor shield 5, braid 4 forms, ground wire consists of ground wire aluminium alloy conductor 9 wrap insulate layers 8, four described main cores 3 are around the symmetrical stranded formation cable core of ground wire 7, and the cable core skin is enclosed with belting layer 2 and flame retardant sheath layer 1, between described belting layer 2 and flame retardant sheath layer 1, along the vertical aspect of cable, sensing fiber 10 is set.Wherein, described conductor is by multiply nickel plating soft copper silk stranded forming in the same way.Described flame retardant sheath layer is comprised of carbon fiber shielding internal layer and the fireproof silicone rubber external sheath layer that is positioned at its outer surface, between described shielding internal layer and external sheath layer, is provided with one and weaves by some dacron threads the terylene woven reinforced layer that forms.Described terylene woven reinforced layer is coated with by the wrapped heat insulation reinforced layer that forms of some high temperature resistant stainless steel alloy silk ribbons.
In order to increase heat insulating effect, the described coated insulation layer outside is coated with by the wrapped thermal insulation layer that forms of some polymethyl methacrylate silk ribbons, and described thermal insulation layer is coated with by the wrapped heat insulation reinforced layer that forms of some high temperature resistant stainless steel alloy silk ribbons.
The improvement that the utility model carries out mainly for high flame retardant double shield silicone rubber for cable structure, the foregoing is only the utility model preferred embodiment, non-so namely limit to the scope of the claims of the present utility model, therefore simple and easy variation and the equivalent transformation of such as with the utility model specification and graphic content, doing, all should be contained in the scope of the claims of the present utility model.
