Abstract
The utility model discloses a novel isolated mineral insulation fireproof cable which is composed of multiple insulating wire cores and a protection outer layer. The protection outer layer wraps the multiple insulating wire cores. An isolation layer is arranged between the insulating wire cores and the protection outer layer. Each insulating wire core includes conductors, a ceramic silicone rubber composite insulation layer and a cross linked polyethylene insulation layer. The protection outer layer sequentially includes an inner wrapping layer, an oxygen-blocking layer, a steel belt armor layer, an outer wrapping layer and a halogen-free low-smoke polyolefin outer sheath from inside to outside. Two or more insulating wire cores are provided. Each conductor is formed by twisting multiple plies of soft copper wires. The isolation layer and the oxygen-blocking layer are formed by extruding a halogen-free low-smoke flame-retardant material having an oxygen index no smaller than 45%. The novel isolated mineral insulation fireproof cable reserves characteristics of a conventional mineral insulation cable of being resistant to high temperatures, fireproof, nontoxic, resistant to aging and the like, and also has the property of a common fireproof cable of being flexible, capable of long-length production, simple production technology, convenient laying installation and the like. The cable does not need baking and heating during an installation process. Further, the laying installation has a small bending radius, and thus the novel isolated mineral insulation fireproof cable has very good practical value and market prospect.
Description
Technical field:
The utility model relates to a kind of cable, particularly relates to a kind of novel isolated form mineral insulated cable, belongs to power cable technical field.
Background technology:
Common power cable does not possess fire-proof function at present, cannot be applied in and require high temperature resistant, fire-resistant use occasion, as skyscraper, national heavy construction, petrochemical industry, subway and city network etc., once breaking out of fire, common cable can be extended to the intensity of a fire all devices of connection, the every nook and cranny of building, produces a large amount of toxic smogs simultaneously, has increased fire damage, and bring difficulty to rescue work, therefore cable fire-proof problem is particularly important.
General mineral insulation hot-face insulation, though have splendid fire resistance, manufacturing process complexity as magnesium oxide mineral insulated cable, need production equipment special, production cost is high, and magnesium oxide insulated is after multiple tracks processing compacting, cable is partially hard, and bending property is bad, and cable can not be produced by big-length.
Wrapped hot-face insulation cable, has improved above-mentioned shortcoming, adopts and between conductor and insulating barrier, increases Mica tape layer, can stand certain hour, the time of more electricity consumptions while escaping to people in fire.But cable can burn very soon in fire, mica tape embrittlement after fire directly burns easily comes off, and can not in fire, really play fireproof effect.
Utility model content:
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, a kind of have explosion-proof, waterproof, anticorrosion, anti-interference, fire-retardant, high fire-resistant, the novel isolated form mineral insulated cable can big-length produced are provided.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of novel isolated form mineral insulated cable, by multiple insulated wire cores and protection skin, formed, described protection skin surrounds multiple insulated wire cores outside, between insulated wire cores and protection skin, be provided with separator, described insulated wire cores comprises conductor, the rubber combined insulating barrier of ceramic silicon and crosslinked polyetylene insulated layer, and described protection skin comprises interior belting layer, oxygen barrier layer, steel-tape armouring layer, outer belting layer and low smoke, zero halogen polyolefin oversheath from inside to outside successively.
Described insulated wire cores is two or more.
Described conductor is closed and is formed by multiply soft copper skein silk.
The rubber combined insulating barrier of described ceramic silicon forms by ceramic silicon rubber composite band is wrapped.
The gap that described separator extrudes the multiple insulated wire cores of filling by oxygen index >=45% LSOH anti-flaming material forms.
Described oxygen barrier layer is extruded and is formed by oxygen index >=45% LSOH anti-flaming material.
Positive beneficial effect of the present utility model is as follows:
Novel isolated form mineral insulated cable of the present invention is met after fire, and oxygen barrier layer is met fire and resolved into metal oxide and crystallization water, after metal oxide decomposes, forms network structure, and flue gas is had to certain suction-operated.And the crystallization water of separating out not only plays obvious settlement action to soot, but also there is good endothermic effect.In this external combustion process, can form carbonized structure, this charring layer is being brought into play huge effect aspect the low cigarette of cable, fire-retardantization, burning rate when heat-absorbing action has postponed that cable itself takes fire and the time of sharply rising, due to the formation of carbonized structure, thereby the supply of oxygen and flowing of fuel gas have been hindered, the burning of therefore having resisted cable.Therefore when high temperature is attacked, by the obstruction of oxygen barrier layer and separator, make insulation under anaerobic, segregate environment, under the high temperature and flame calcination of the rubber combined insulating barrier of ceramic silicon more than 500 ℃, its organic principle changes into hard ceramics shape material within the utmost point short time, forms the flame barrier layer of good insulation properties, and increase with calcination time, temperature raises, and its hardness is more obvious, has effectively improved the fire resistance of insulated wire cores.In addition, steel-tape armouring layer has not only improved the externally effect of defence of cable, reaches the jamproof effect of anticollision, rat-and-ant proof and resistance to compression, and steel-tape armouring layer has also played the effect of fire insulation and oxygen barrier simultaneously.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Referring to Fig. 1, a kind of novel isolated form mineral insulated cable, by multiple insulated wire cores and protection skin, formed, protection skin surrounds multiple insulated wire cores outside, between insulated wire cores and protection skin, be provided with separator 4, insulated wire cores comprises conductor 1, the rubber combined insulating barrier 2 of ceramic silicon and crosslinked polyetylene insulated layer 3, and protection skin comprises interior belting layer 5, oxygen barrier layer 6, steel-tape armouring layer 7, outer belting layer 8 and low smoke, zero halogen polyolefin oversheath 9 from inside to outside successively.Wherein: insulated wire cores is two or more, conductor 1 is closed and is formed by multiply soft copper skein silk, the rubber combined insulating barrier 2 of ceramic silicon forms by ceramic silicon rubber composite band is wrapped, the gap that separator 4 extrudes the multiple insulated wire cores of filling by oxygen index >=45% LSOH anti-flaming material forms, and oxygen barrier layer 6 is extruded and formed by oxygen index >=45% LSOH anti-flaming material.
This utility model is compared with fire-resisting cable in the past, can reduce production costs, be convenient to laying installation, safe and reliable, both retained high temperature resistant, the fire prevention of traditional mineral insulated cable, the characteristic such as nontoxic, ageing-resistant, taken into account again simultaneously common fire-resisting cable flexibility, can big-length produce, the characteristic such as production technology is simple and easy for installation, when cable is installed without Baking out, and laying installation bending radius is little, there are good practical value and market prospects.
