Abstract
The invention discloses a fireproof cable for a nuclear power station. The fireproof cable comprises conductors, polyester belts, an insulation layer, a flame-retardant layer, a braid layer and an external sheath, wherein the braid layer is wrapped by the external sheath; the flame-retardant layer is wrapped by the braid layer; the insulation layer is wrapped by the flame-retardant layer; the polyester belts are wrapped by the insulation layer; the conductors are wrapped by the polyester belts. The fireproof cable is anti-interference, the gaps among cores of the cable are filled with glass fiber, and the cable is fastened with glass fiber cloth, so that the high-temperature resistance and the flame resistance are excellent; an aluminum foil layer, which is excellent in anti-interference performance, is adopted.
Description
Technical field
The present invention relates to a kind of cable, particularly relate to a kind of control cables with anti-interference fire resistance.
Background technology
At present, in cable industry, fireproof control cable generally adopts the wrapped mode adding insulation of fire-resistant isinglass belt, but Mica tape class fire-resisting cable is in wrapped or bending process, mica sheet easily comes off, not by spray, vibratory test, and mica tape kind is more again now, and quality is uneven, less stable, is difficult to the fire resistant quality ensureing cable.Secondly, the insulation that common fireproof control cable uses and sheath material mostly all contain halogen or do not reach the environmental requirement of European Union ROHS instruction.Moreover the wrapped production of small bore fireproof control cable is restricted, and fire resistance quality more cannot be protected.And the poor anti jamming capability of such cable.
Summary of the invention
The object of this invention is to provide a kind of fireproof cables of nuclear power, to overcome the technological deficiency of existing fire-resisting cable, improve the fire resistance of cable, environmental-protecting performance and interference free performance.
Fireproof cables of nuclear power of the present invention, comprise conductor, polyester belt, insulating barrier, flame-retardant layer, braid and oversheath, described oversheath is wrapped in the skin of braid, described braid is wrapped in the skin of flame-retardant layer, described flame-retardant layer is wrapped in the skin of insulating barrier, described insulating barrier is wrapped in the skin of polyester belt, is enclosed with conductor in described polyester belt.
As preferably, described insulating barrier is LSOH anti-flaming second third insulating barrier.
As preferably, described flame-retardant layer is low-smoke non-halogen flame-retardant band.
As preferably, described braid is that aluminium plated steel wire braiding forms.
As preferably, described oversheath is that heat is because of property oversheath.
Fireproof cables of nuclear power of the present invention filled glass fiber silk in the gap of cable conductor, and tighten with glass fabric band, have well high temperature resistant and fire resistance, aluminium foil layer just has good anti-interference.
Due to refractory ceramics fire-resistant silicon rubber use working temperature higher, can reach 180 DEG C and more than, substantially increase the ampacity of cable, cable is in same ampacity situation, and cross section can reduce further.
Fireproof cables of nuclear power of the present invention has fire-resistant, environmental protection, the interference free performance of excellent electrical insulation capability, interference free performance and excellence, and processing technology is simple, and transport is laid conveniently, and cost performance is higher.
Accompanying drawing explanation
Fig. 1 is the structural representation of fireproof cables of nuclear power of the present invention.
Embodiment
Below by way of specific embodiment, and the invention will be further described by reference to the accompanying drawings.
The structure of fireproof cables of nuclear power as shown in Figure 1, comprise conductor 1, polyester belt 2, insulating barrier 3, flame-retardant layer 4, braid 5 and oversheath 6, described oversheath 6 is wrapped in the skin of braid 5, described braid 5 is wrapped in the skin of flame-retardant layer 4, described flame-retardant layer 4 is wrapped in the skin of insulating barrier 3, described insulating barrier 3 is wrapped in the skin of polyester belt 2, is enclosed with conductor 1 in described polyester belt 2.
It should be noted that described insulating barrier 3 is LSOH anti-flaming second third insulating barrier.
It should be noted that described flame-retardant layer 4 is low-smoke non-halogen flame-retardant band.
It should be noted that described braid 5 forms for aluminium plated steel wire weaves.
It should be noted that described oversheath 6 is for heat is because of property oversheath.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, and any change of expecting without creative work or replacement, all should be encompassed within protection scope of the present invention.Therefore, the protection range that protection scope of the present invention should limit with claims is as the criterion.
