Abstract
The invention discloses a fireproof cable used inside a nuclear island of a nuclear power station. The fireproof cable comprises a cable core which is formed by intertwisting a plurality of insulating wire cores; the insulating wire cores consist of conductors and insulating layers extruded outside the conductors; and gaps after intertwisting of the cable core is filled with mineral filling layers, a ceramic silicone rubber composite belt wraps the cable core, and an outer sheath is extruded at the outermost layer of the cable core. The fireproof cable used inside the nuclear island of the nuclear power station has-low smoke, halogen-free, environment-friendly, and acid-alkali-resistant performance, and satisfies the requirements of long service life, reliability and the like.
Description
Technical field
The present invention relates to electric wire field, in especially a kind of nuclear island of nuclear power station, use fire-resisting cable.
Background technology
Due to the Special use environment in nuclear island of nuclear power station, the mounting and installation of operational outfit and use are had to very high requirement.In nuclear island with cable except possessing the electric property of common cable, also need to possess low cigarette, Halogen, environmental protection, acid-proof alkaline, also to can meet the requirements such as long-life high reliability simultaneously.
Existing fire-resistant wire and cable, takes on conductor, after wrapped mica tape, to extrude PVC or XLPE, and this kind of technique can not meet the low-smoke non-halogen flame-retardant demand of cable for nuclear power station.
Summary of the invention
The invention reside in to provide in a kind of nuclear island of nuclear power station and use fire-resisting cable, possess low cigarette, Halogen, environmental protection, acid-proof alkaline, met high life, reliability requirements simultaneously.
For solving above technical problem, in a kind of nuclear island of nuclear power station of the present invention, with fire-resisting cable, comprise cable core, cable core is by many stranded the forming of insulated wire cores; Described insulated wire cores consists of conductor and the insulating barrier that is extruded in outside conductor; Gap filling mineral packed layer after cable core is stranded, the outer wrapped ceramic silicon rubber composite band of cable core, cable core outermost layer extrudes oversheath.
Further improve, described insulating barrier consists of ceramic silicon rubber insulation material.
Further improve, described oversheath consists of thermoplastic low-smoke halide-free fireproof composite polyolefine material.
Compared with prior art, beneficial effect of the present invention:
1, production technology is simple, and quality is easy to control, and because insulation adopts ceramic silicon rubber composite material, forms hard ceramic fireproof jointing sheath during burning, plays a part isolated flame.
2, product structure is simple, and without wrapped mica material, production technology is simple.
3, cable has excellent bending property, and high temperature resistant, fire resistance can be spent long-term work under hot environments long-term 300, and performance does not decline.
4, cable has possessed low cigarette, Halogen, fire resistance and high insulating property.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated:
As shown in Figure 1, in a kind of nuclear island of nuclear power station of the present invention, with fire-resisting cable, comprise cable core, cable core is by five stranded forming of insulated wire cores; Described insulated wire cores consists of conductor 1 and the insulating barrier 2 consisting of ceramic silicon rubber insulation material that is extruded in outside conductor 1; Gap filling mineral packed layer 3 after cable core is stranded, the outer wrapped ceramic silicon rubber composite band 4 of cable core, cable core outermost layer extrudes the oversheath 5 consisting of thermoplastic low-smoke halide-free fireproof composite polyolefine material.
Above-mentioned is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvement and adjustment, these improvement and adjustment also should be considered as protection scope of the present invention.
Claims (3)
