Description
Technical field
The utility model relates to cable, particularly relates to a kind of low-smoke non-halogen flame-retardant fire resistant flexible midium voltage cable.
Background technology
Order is along with the fast development of national economy and improving constantly of living standards of the people, and social power consumption greatly increases.The steep increasing of various electric equipment consumption, electrical fire accident also increases severely thereupon.According to statistics, the annual breaking out of fire of China about more than ten ten thousand, direct property loss more than 10 hundred million yuan.Wherein, account for 30% of sum by the fire that electrically reason causes such as electric wire short circuit, excess load, electric equipment fault, the frequency of electrical fire and the loss caused all occupy first of all kinds of fire.In electrical fire, the fire caused by electric wire accounts for half.Therefore more and more pay attention to about the low-smoke non-halogen flame-retardant of electric wire and fire safety problem people, to the low-smoke non-halogen flame-retardant of electric wire and fire protection requirement also more and more higher.
So just require that the environment of use cable on the one hand will ventilate, dry, space is open, perfect heat-dissipating should possess and have certain defencive function to cable, this is obviously difficult to accomplish, require on the other hand cable craft technological performance, low smoke and zero halogen, fire prevention, waterproof, decay resistance is strong, mounting and installation is convenient, fail safe is high fireproof cable, it has that mineral insulated cable is high temperature resistant concurrently, fire prevention, LSZH, the excellent specific property such as ageing-resistant, also overcome mineral insulated cable bending property poor, the easy moisture absorption simultaneously; The shortcomings such as joint is many, installation is inconvenient, also do not have a kind ofly have low smoke and zero halogen, fire-retardant, fire prevention, waterproof, decay resistance is strong, mounting and installation is convenient, fail safe is high flexible fire-proof cable up to now.
Utility model content
For meeting above-mentioned requirements, the utility model object is to provide a kind of low-smoke non-halogen flame-retardant fire resistant flexible midium voltage cable.
Scheme of the present utility model is as follows: a kind of low-smoke non-halogen flame-retardant fire resistant flexible midium voltage cable, comprises power wire core, interior oxygen barrier layer, steel wire reinforcing layer, outer oxygen barrier layer and oversheath; Described power wire core extrudes two class soft copper conductors successively by metal screen layer, crosslinked polyetylene insulated layer and conductor shield to form; Described interior oxygen barrier layer extrudes three power wire core and becomes cable core, and described cable core internal clearance is provided with gasket for packing, is disposed with outer oxygen barrier layer and oversheath outside cable core; Steel wire reinforcing layer is provided with between described interior oxygen barrier layer and outer oxygen barrier layer.
Insulation screen is provided with between described metal screen layer and crosslinked polyetylene insulated layer.
The beneficial effects of the utility model: the utility model structural design is simple, stable performance, soft, lightweight, low smoke and zero halogen, corrosion resistance is strong, and flameproof effect is good, and the effective electromagnetic interference suppressing inside and outside boundary, security performance is good.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Wherein: 1, two class soft copper conductors; 2, conductor shield; 3, crosslinked polyetylene insulated layer; 4, insulation screen; 5, metal screen layer; 6, gasket for packing; 7, interior oxygen barrier layer; 8, steel wire reinforcing layer; 9, outer oxygen barrier layer; 10, oversheath.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, a kind of low-smoke non-halogen flame-retardant fire resistant flexible midium voltage cable, comprises power wire core, interior oxygen barrier layer 7, steel wire reinforcing layer 8, outer oxygen barrier layer 9 and oversheath 10; Described power wire core extrudes two class soft copper conductors 1 successively by metal screen layer 5, crosslinked polyetylene insulated layer 3 and conductor shield 2 to form; Described interior oxygen barrier layer extrudes three power wire core and becomes cable core, and described cable core internal clearance is provided with gasket for packing, is disposed with outer oxygen barrier layer 9 and oversheath 10 outside cable core; Steel wire reinforcing layer is provided with between described interior oxygen barrier layer 7 and outer oxygen barrier layer 9.Described interior oxygen barrier layer 7 and outer oxygen barrier layer 9 all adopt inorganic mineral oxygen barrier material to extrude and form; Described steel wire reinforcing layer 8 adopts that high-tensile steel wires are wrapped to be formed; Described oversheath 10 adopts low smoke and zero halogen, fire-retardant, corrosion resistant protective cover material extrudes and forms.Steel wire reinforcing layer plays load-bearing effect, and cable can length vertically be installed greatly; During breaking out of fire, inside and outside oxygen barrier layer 9 heat absorption heat can produce certain steam prevention flame to the extension of cable inside, extends the fire rescue time.When employing low smoke and zero halogen, fire-retardant, corrosion-resistant sheath breaking out of fire, sheath can not be burned at once, LSZH during burning, and corrosion resistance is strong, harmless.Be applicable to the skyscraper of large size city, public place of entertainment and numerous supply line requiring Fire lift in the construction project of high-quality and high safety, subway, tunnel, metallurgy, fire-fighting system, fire pump, fire alarm, smoke evacuation system, emergency lighting and fire hazard district, high temperature occasion and require the aspects such as ultra-safe facility, Main Function is for not cutting off the electricity supply when breaking out of fire, can reach again the object of safety guarantee.
Be provided with insulation screen 4 between described metal screen layer 5 and crosslinked polyetylene insulated layer 3, insulation screen 4 adopts semiconductive material to extrude and forms.
Although give detailed description and explanation to embodiment of the present utility model above; but what should indicate is; we can carry out various equivalence according to conception of the present utility model to above-mentioned execution mode and change and amendment; its function produced do not exceed that specification contains yet spiritual time, all should within protection range of the present utility model.
