Description
Technical field
The utility model relates to cable, particularly relates to a kind of mineral insulating flexible fireproof cable.
Background technology
Along with the fast development of national economy and improving constantly of living standards of the people, 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, also there is no a kind of to there is 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 mineral insulating flexible fireproof cable.
Scheme of the present utility model is as follows: a kind of mineral insulating flexible fireproof cable, comprises three eradication edge power wire core and a neutral core; Described insulated power core extrudes two class soft copper conductors successively by color separation protective layer, mineral synthetic mica tape to form; Described neutral core is extruded on fibre core by the zinc-plated soft copper conductor of five classes to form, and the zinc-plated soft copper conductor of five classes is outside equipped with polyethylene layer; Three thoroughly do away with edge power wire core extrudes into cable core with a neutral core and inorganic glass fibre gasket for packing, sets gradually inorganic mineral belting layer, fire-retardant fireproof layer and oversheath outside described cable core.
Described fire-retardant fireproof layer adopts copper strips to indulge the structure of bag welding embossing.
Described color separation protective layer is the structure that inorganic mineral band lapping layer increases ribbon identification outward.
The beneficial effects of the utility model: the utility model structural design is simple, low cigarette, Halogen, fire prevention, mounting and installation is convenient, flexible, and the effective electromagnetic interference suppressing inside and outside boundary, insulated power core and neutral core are easy to identification, and 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, mineral synthetic mica tape; 3, color separation protective layer; 4, inorganic glass fibre gasket for packing; 5, fibre core; 6, inorganic mineral belting layer; 7, fire-retardant fireproof layer; 8, oversheath; 9, the zinc-plated soft copper conductor of five classes; 10, polyethylene layer.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further;
As shown in Figure 1, a kind of mineral insulating flexible fireproof cable, comprises three eradication edge power wire core and a neutral core; Described insulated power core extrudes two class soft copper conductors 1 successively by color separation protective layer 3, mineral synthetic mica tape 2 to form; Described neutral core is extruded on fibre core 5 by the zinc-plated soft copper conductor 9 of five classes to form, and the zinc-plated soft copper conductor 9 of five classes is outside equipped with polyethylene layer 10; Three thoroughly do away with edge power wire core extrudes into cable core with a neutral core and inorganic glass fibre gasket for packing 4, sets gradually inorganic mineral belting layer 6, fire-retardant fireproof layer 7 and oversheath 8 outside described cable core.Inorganic mineral belting layer 6 can play oxygen barrier effect when breaking out of fire, extends the fire rescue time.Soft, the soft good bandability of this construction of cable plays again resistance to fire action, 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.
Described fire-retardant fireproof layer 7 adopts copper strips to indulge the structure of bag welding embossing, copper strips vertical bag welding embossing softness, good bending property and fire protecting performance are good, when low smoke and zero halogen, fire-retardant, corrosion-resistant sheath breaking out of fire, sheath can not be burned at once, LSZH during burning, corrosion resistance is strong, harmless.The structure that bag welding embossing indulged by copper strips is also best shielding protection layer, cable itself both can have been prevented the interference of other cable, external electromagnetic field can be stoped again to disturb.
Described color separation protective layer 3 is structures that inorganic mineral band lapping layer increases ribbon identification outward.
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.
