本实用新型公开了一种铜芯辐照聚烯烃护套阻燃耐火电力电缆，包括包覆绝缘层的导体组成的主线芯、填充线芯、包覆主线芯和填充线芯的包带，并在所述包带外部包覆内护套和外护套，其特征在于在主线芯、填充线芯和包带之间的空隙添加耐火层，当电缆燃烧时，耐火胶料受热分解，释放出结晶水及吸热，并在绝缘层表面形成一覆盖层，覆盖层隔绝了氧气的助燃作用，使绝缘有机物受到保护，结晶水的析出，水蒸气的蒸发吸收了大量热能，降低了周围环境温度，着火电缆将逐渐自行熄灭。
The utility model discloses a flame-retardant and fire-resistant power cable with a copper core irradiated polyolefin sheath, which comprises a main wire core composed of a conductor covering an insulating layer, a filling wire core, a tape covering the main wire core and the filling wire core, and Cover the inner sheath and the outer sheath on the outside of the tape, which is characterized in that a refractory layer is added to the gap between the main core, the filling core and the tape. When the cable burns, the refractory rubber is decomposed by heat and released Crystal water absorbs heat and forms a covering layer on the surface of the insulating layer. The covering layer isolates the combustion-supporting effect of oxygen and protects the insulating organic matter. The precipitation of crystal water and the evaporation of water vapor absorb a large amount of heat energy and reduce the temperature of the surrounding environment. , the fire cable will gradually extinguish itself.
Description
Technical field
The utility model relates to a kind of cable technology field, particularly a kind of copper core irradiation polyolefin jacket flame-retardant power cable.
Background technology
Power cable be electric power system in circuit in order to transmission with distribute the cable product of high-power electric energy, often be applied to the places relevant, important place such as subway, tunnel, power station, petrochemical industry, high-rise, industrial and mining enterprises, as fire-fighting equipment, fire alarm, communication fume extractor and urgent electric power system to emergency sets such as leading lights with fire safety and fire-fighting.
These uses have high requirements to the cable-flame retardant performance, though existing fireproof power cable has certain fire-resistant function, but when catching fire for a long time, can produce other chemical toxic gas of halogen gas and some, produce a large amount of flue gases, harmful to health, and the existing power cable cannot be put out a fire voluntarily, and when being burned to uniform temperature, cable will damage, cannot use for a long time, cause the certain economic loss.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of copper core irradiation polyolefin jacket flame-retardant power cable, when cable fire, do not produce halogen gas or chemical toxic gas and flue gas, and cable can be put out a fire voluntarily.
The utility model is to realize by following technical scheme:
A kind of copper core irradiation polyolefin jacket flame-retardant power cable, the band that comprises master core, filling core, coating master core and the filling core of the conductor composition of coated insulation layer, and at outside inner sheath and the oversheath of coating of described band, flame retardant coating is added in the space between master core, filling core and band.
The assembling radical of described master core+filling core can be 3+1,3+2 or 4+1 root.
When described copper core irradiation polyolefin jacket flame-retardant power cable need be dressed up armoured cable, between described inner sheath and oversheath, add one deck armour.
Described flame retardant coating is made up of fire-resistant sizing material.
The beneficial effects of the utility model are: added the flame retardant coating that one deck is made up of fire-resistant sizing material in cable; when cable fire; fire-resistant sizing material decomposes; discharge the crystallization water and heat absorption; and form a cover layer at surface of insulating layer; cover layer has completely cut off the combustion-supporting effect of oxygen; the insulation organic substance is protected; separating out of the crystallization water; the evaporation of steam has absorbed a large amount of heat energy, has reduced ambient temperature, and the cable that catches fire will be gradually from horizontal blanking; the fire resistance of cable is reliable and stable, has reduced use cost.
Description of drawings
Fig. 1 is the structure chart of copper core irradiation polyolefin jacket flame-retardant power cable
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
Fig. 1 is the structure chart of copper core irradiation polyolefin jacket flame-retardant power cable; adopt 4 cored structures to illustrate among this figure; the master core 9 that comprises conductor 1 composition of coated insulation layer 2; fill core 8; wherein conductor 1 is the copper core; insulating barrier 2 is the crosslinked polyethylene organic substance; filling core 8 is neutral core; play filling effect; place the stressed crimp of cable internal structure; reduce useful life; outside at master core 9 and filling core 8 coats band 4; can make the compact conformation of core; and at the outside of described band 4 coating inner sheath 5 and oversheath 7; sheath is the polyethylene insulation material; at master core 9; flame retardant coating 3 is added in the space of filling between core 8 and the band 4; flame retardant coating 3 is by nontoxic; smokelessly; not molten; do not fire; not halogen-containing fire-resistant sizing material is formed; when cable fire; fire-resistant sizing material decomposes; discharge the crystallization water and heat absorption; and at insulating barrier 2 surface formation one cover layer; cover layer has completely cut off the combustion-supporting effect of oxygen; the insulation organic substance is protected, the separating out of the crystallization water, the evaporation of steam has absorbed a large amount of heat energy; reduced ambient temperature; catching fire cable will be gradually from horizontal blanking, through the basis of flame retardant coating 3 technical finesses its burning smoke density of power cable be improved significantly, can reach Halogen; low toxicity; the requirement of low cigarette; because cable-flame retardant is stable and reliable for performance, use cost reduces greatly.
In actual applications, sometimes need this cable is assembled into armoured cable, armoured cable is to be contained in the sleeve pipe of insulating material by different material conductors, be processed to flexible solid assembly, in use, allow flexibility to strengthen greatly, so as need be assembled into armoured cable in actual use the time, need between inner sheath 5 and oversheath 7, to add with individual armour 6.
In actual production, according to the demand of different fields of employment, this cable can be assembled into different specifications, for example, the assembling radical of the described master core+filling core of this cable can be able to be 3+1,3+2 or 4+1 root, improve the use flexibility ratio of this cable.
