Abstract
The invention discloses an environment-friendly medium-voltage fireproof cable comprising a middle cable core, a ceramic composite belt, a high anti-flaming belting layer, an oxygen separation insulating layer, a steel belt armoring layer and a sheath layer extruded at the outermost side, wherein the ceramic composite belt, the high anti-flaming belting layer, the oxygen separation insulating layer and the steel belt armoring layer are sequentially coated outside the cable core; a filling strip is filled in a gap between the cable core and the ceramic composite belt; the cable core is formed by mutually stranding three cores in triangular symmetrical distribution; each core consists of a middle conductor, a conductor shield layer, an insulating layer, an insulating shield layer and a metal shield layer; and the conductor shield layer, the insulating layer, the insulating shield layer and the metal shield layer are sequentially coated outside the conductor. The cable is severely blazed by flames, so that the ceramic composite belt can rapidly generate a hard ceramic layer, and the flames are prevented from continuously blazing inward. The environment-friendly medium-voltage fireproof cable is applicable to the fields with the high anti-flaming requirement, such as high-rise buildings, oil platforms, mines, metallurgy, ships, power stations, airplanes, stations, tunnels and the like.
Description
Technical field
The present invention relates to the power cable field, specifically press fireproof cable in a kind of environment-friendly type.
Background technology
At present, the high occasions of fire protection requirement such as domestic skyscraper, oil platform, mine, metallurgy, boats and ships, power station, subway, airport, station, tunnel, most material that adopts Halogen in the cable insulation that uses, restrictive coating.In case breaking out of fire not only can produce a large amount of dense smoke, and can produce the very strong hydrogen halide of corrosivity with " secondary disaster ", not only easily damage equipment and contaminated environment even jeopardize people's life.Even adopt the fire proofing of low smoke, zero halogen, also can only delay the time that fire proofing is burnt till powder.If continue to be burnt, will gradually powder comes off, and has lost protective effect, easily make electric wire breakdown and cause short circuit, thereby has affected safe and smooth under fire condition of communication, electric power.Along with the requirement to environmental protection of the high speed development of World Economics and World Environment Organization, anxious a kind of environmental type to be developed is set fire cable to satisfy the needs of human kind sustainable development, and this is the development trend of countries in the world cable technology.
Summary of the invention
In order to address the above problem, the present invention presses fireproof cable produce a kind of environment-friendly type on the basis of rated voltage 6/10kV～26/35kV midium voltage cable in, and cable still can be worked on when breaking out of fire.
Cable core in the middle of the structure of this cable comprises, and be coated on successively the outer ceramic composite band of cable core, the high flame retardant belting layer, the oxygen barrier separator, steel-tape armouring layer and be extruded in outermost restrictive coating is filled with the packing that the high flame retardant glass fiber material is made in the space between cable core and ceramic composite band.Described cable core is by symmetrical mutual stranded formation of three cores of triangularity, and every core is all by the conductor of centre, and is coated on successively the outer conductor shield of conductor, insulating barrier, and insulation screen, metal screen layer forms.
Further improve, described conductor is to press the strand system by the some identical soft round copper wires of diameter to form; Conductor shield, insulation screen adopt semi-conductive shielding material to extrude; Insulating barrier adopts cross-linked polyethylene insulating material to extrude; Metal screen layer is wrappedly to consist of by the soft copper band is overlapping.
Further improve, described ceramic composite band is composited by ceramic fireproof＝fire-proof silicon rubber and the calendering of high temperature resistance glass fiber cloth, and is overlapping wrapped on cable core.
Further improve, described high flame retardant belting layer is overlapping wrapped the forming of high flame retardant glass strap; The oxygen barrier separator is for extruding the halogen-free and low-smoke flame-retardant polyolefin plastic layer.
Further improve, described steel-tape armouring layer is double-deck galvanized steel strip gap winding arrangement, and its gap is not more than 50% of bandwidth.
Further improve, described restrictive coating is for extruding environment friendly non-halogen low-smoke flame-proof polyolefin plastic layer, its oxygen index＞35%.
Beneficial effect of the present invention is:
1, adopt the fire proofing of low smoke, zero halogen, safety and environmental protection.
When 2, meeting fire, cable is under the violent burning of flame, the ceramic composite band can generate rapidly a kind of hard ceramic layer, stop flame to continue to internal combustion, be applicable to the high occasions of fire protection requirement such as skyscraper, oil platform, mine, metallurgy, boats and ships, power station, subway, airport, station, tunnel.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Embodiment
As shown in Figure 1, be an example of this novel flame-retardant frequency-conversion power cable cable, the some identical soft round copper wires of diameter are pressed be stranding into conductor, conductor outer cladding conductor shield more successively, insulating barrier, insulation screen and metal screen layer form core.Three cores that triangularity is symmetrical are twisted into cable core mutually, put into packing in the cable core surrounding, coating ceramic composite band successively from inside to outside, and the high flame retardant belting layer, the oxygen barrier separator, the steel-tape armouring layer, outermost extrudes restrictive coating.
The present invention's conductor shield 2, insulation screen 4 used adopts semi-conductive shielding material to extrude; Insulating barrier 3 adopts cross-linked polyethylene insulating material to extrude; Metal screen layer 5 wrappedly consists of by the soft copper band is overlapping; Packed layer 6 is made of the high flame retardant glass fiber material; Ceramic composite band 7 is composited by ceramic fireproof＝fire-proof silicon rubber and the calendering of high temperature resistance glass fiber cloth, and is overlapping wrapped on cable core; High flame retardant belting layer 8 is overlapping wrapped the forming of high flame retardant glass strap; Oxygen barrier separator 9 is for extruding the halogen-free and low-smoke flame-retardant polyolefin plastic layer; Steel-tape armouring layer 10 is not more than 50% the double-deck galvanized steel strip gap winding arrangement of bandwidth for the gap; Restrictive coating 11 is for extruding environment friendly non-halogen low-smoke flame-proof polyolefin plastic layer, its oxygen index＞35%.
The concrete application approach of the present invention is a lot, and the above is only the preferred embodiment of the present invention, should be understood that; for those skilled in the art; under the prerequisite that does not break away from the principle of the invention, can also make some improvement, these improvement also should be considered as protection scope of the present invention.
