Description
Technical field
The present invention relates to a kind of fire-resisting flexible cable, a kind of specifically refractory temperature can be widely applied to business up to 1050 DEG C
The low-smoke zero-halogen fire-resistant flexible cable in the large-scale densely populated place such as field, hotel.
Background technology
With the continuous high speed development of China's economy, the important public affairs such as the office building of modernization, hotel, restaurant, railway station
Place decoration becomes all the more luxurious altogether, and the combustible used is also more and more.Electric wire effect is to transmit electric power, signal, real
Now alarm, the startup of fire fighting device, rescue etc., for above-mentioned densely populated type place, after fire occurs, if electric wire
It cannot ensure normal work, then consequence is hardly imaginable.
Fire-resistant wires are exactly to ensure circuit normal power-up, the various controls of transmission, report in certain time when fire occurs
Alert signal, with ensure when fire occurs the illumination of passage, emergent broadcast, fire protection alarm device, automatic fire-fighting facility and its
The normal power supply of its emergency set, makes personnel evacuate in time, rescue work is normally carried out, it is seen that fire-resistant wires it is reliable
Property is most important.As country payes attention to the gradual of fireproofing, the awareness of safety of people also steps up.In order to improve electric appliance
The safe class of circuit, reduces the generation and loss of electrical fire accident, Minstry of Housing and Urban-Rural Development of People Republic of China (MOHURD), the Ministry of Public Security and some local governments
Some electrical design specifications are promulgated in succession, and clear stipulaties preferably use flame proof electrical in some important electric appliance circuits or place
Cable, world community man is also in rising trend year by year to the demand of fire-resistant wire and cable product, in order to ensure public place
Security against fire problem Deng important events should widely popularize the fire-resisting cable of selection fire resistant flame retardant, low smoke and zero halogen.
However, the common fire-resisting cable of Current Domestic is generally only capable of reaching highest refractory temperature as 750~850 DEG C, i.e.,
Make in the refractory standard in the Europe of BS 6387, highest refractory temperature also only has 950 DEG C, once large-sized fire occurs, temperature exceedes
At 950 DEG C, which will lose resistance to fire action.It is known that cable is generally copper with the material of conductor, and copper is molten
Point is 1083.4 DEG C, and therefore, home and abroad skilled addressee can be more than 950 DEG C and low in a kind of fire resisting maximum temperature of research
In the fire-resisting cable of the fusing point of copper.
The content of the invention
The object of the present invention is to provide a kind of low-smoke zero-halogen fire-resistant flexible cable, and the refractory temperature of the flexible cable is up to 1050 DEG C.
In order to reach above-mentioned technical purpose, the technical scheme is that：
A kind of low-smoke zero-halogen fire-resistant flexible cable, ecto-entad include restrictive coating, insulating layer, mica belt and conductor successively.

Product are only capable of meeting 80 DEG C of high temperature resistant pressure testings.The product is such as made during actual use is generated heat by weight or certain pressure
With can ensure that insulation, the thickness of sheath are unlikely by more serious infringement, insulation, the thickness of sheath ensured, so that more into one
Step improves the safety in utilization of product.The thickness of insulating layer is 0.7~2.4mm.
The mica belt by calcining gold mica tape double-layer overlapping put up it is wrapped pack, the cap rate put up is preferably
50%.
The conductor is twisted by more annealing bare copper wires.Specifically, it is twisted using class5 or class6 thin copper wires
Annealing bare copper conductor, the conductor specification is 1.5mm2~630mm2。
The fire resisting maximum temperature of the cable is 1050 DEG C, duration 120 minutes.
The flexible cable has preferable pliability, and minimum bending radius 5D, D are the outside diameter of cable.
The rated operational voltage of cable of the present invention is 0.6/1 (1.2) kV, the Long-term service temperature of cable conductor is less than or equal to
110 DEG C, cable laying when, environment temperature not less than 0 DEG C, the minimum bending radius of cable can reach 5 times of outside diameter of cable values, even if
Large-sized fire temperature more than 950 DEG C and less than copper fusing point when, which remains to effectively play its effect, greatly improves
The security used, has ensured the life security of personnel.The flexible cable of the present invention substantially increases the temperature of fire resistance, infinitely
Close to the fusing point of copper.Therefore the product can be widely applied to the large-scale densely populated place such as market, hotel, once fire occurs
When, the effect such as safe power supply time, signal transmission of abundance can be provided for circuit, support personnel is dredged in effective period of time
Dissipate.The security that product uses is greatly improved, and has ensured the life security of personnel.
