Abstract
The invention discloses a halogen-free low smoke fireproof control cable. The halogen-free low smoke fireproof control cable comprises seven cable conductor sets, wherein six cable conductor sets are arranged by taking the other one cable conductor set at the center position of the cable as a center and are in a radial tight arrangement mode, the cable conductor sets are respectively in external tangent relations, the cable conductor set comprises a cable conductor arranged at a center position, and a fireproof mica layer and an insulation layer which cover the cable conductor in a wrapping mode, the cable conductor set is tightly wrapped in a steel band belting layer, and the steel band belting layer is sequentially wrapped in an armored layer, a fireproof layer and a halogen-free low smoke sheath. The halogen-free low smoke fireproof control cable solves disadvantages of traditional fireproof control cables, is greatly convenient for fire fighting and personnel evacuation and prevents apparatuses and equipment from being corroded by halogen acid gases.
Description
Technical field
The present invention relates to a kind of control cables, particularly relate to a kind of low smoke, zero halogen fireproof control cable.
Background technology
At present, in Important Economic departments such as various industrial and mining enterprises, communications and transportation, such as, in the enterprises such as power plant, transformer station, power circuit and petrochemical industry, the application of control cables widely, for the running of safe power supply and production system, the function of control cables even exceedes the power cable for backbone.
Control cables (controlcable) is applicable to industrial and mining enterprises, energy traffic department, polyvinyl chloride insulation, pvc sheath control cables for occasions such as ac rated voltage less than 450/750 volt control, protection circuits.The common fault of control cables circuit has that mechanical damage, insulation harm, humidified insulation, ageing of insulation are rotten, overvoltage, cable overheating fault etc.
In actual application, the research and development of control cables in its fire proofing is less, particularly in control cables, the temperature resistant grade of insulating barrier is lower, insulating barrier may burn phenomenon and discharge the pernicious gas such as smog, poison gas at a higher temperature, thus affecting the normal work of control cables, its job security and reliability are difficult to ensure.
In view of the defect that above-mentioned prior art exists, the present invention's actively research and innovation in addition, to founding a kind of low smoke, zero halogen fireproof control cable, makes it have more practicality.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide a kind of low smoke, zero halogen fireproof control cable, to improve the fire resistance of cable, achieving the low smoke, zero halogen burning of cable.
The present invention takes following technical scheme to realize: a kind of low smoke, zero halogen fireproof control cable, it comprises seven groups of cable conductors groups, wherein cable conductors group described in six groups is radially closely arranged centered by the one group of cable conductors group being positioned at this cable center position, mutually circumscribed between described cable conductors group, described cable set is the cable conductors arranged by center and the fireproof mica layer be wrapped in outside cable conductors, insulating barrier forms, it is inner that described cable conductors group is closely wrapped in steel band belting layer, described steel band belting layer is enclosed with armour successively, fireprotection layer and low smoke, zero halogen sheath.
Further, described fireprotection layer inside is provided with several fire guards of closely arranging.
Further, described cable conductors is made up of the zinc-plated same conductor lines bundle closing lay of multiply.
The present invention has following beneficial effect in sum: the shortcoming that instant invention overcomes traditional fireproof control cable, great convenience fire fighting and evacuating personnel work, avoid the replacement type product that the corrosion of halogen acid gas to instrument and equipment becomes traditional fireproof control cable, it mainly contains following characteristics:
1, during cable fire, hydrogen halide burst size is low;
2, during cable fire, the amount of being fuming is few, and light transmittance is high;
3, cable conductor Long-term service temperature can reach 90 DEG C, extends the useful life of cable;
4, be applicable to the occasion such as ac rated voltage 450/750V and following control, monitoring loop and protection circuit, be specially adapted to nuclear power station, fall, the coefficient of safety such as theater requires high important events.
Accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention;
Wherein: 1, cable conductors; 2, fireproof mica layer; 3, insulating barrier; 4, steel band belting layer; 5, armour; 6, fireprotection layer; 7, fire guard; 8, low smoke, zero halogen sheath.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, a kind of low smoke, zero halogen fireproof control cable, it comprises seven groups of cable conductors groups, and wherein cable conductors group described in six groups is radially closely arranged centered by the one group of cable conductors group being positioned at this cable center position.
As preferred version of the present invention, mutually circumscribed between cable conductors group of the present invention, the cable conductors 1 that described cable set is arranged by center and be wrapped in the fireproof mica layer 2 of cable conductors outer 1, insulating barrier 3 forms.
As preferred version of the present invention, it is inner that cable conductors group of the present invention is closely wrapped in steel band belting layer 4, and described steel band belting layer 4 is enclosed with armour 5, fireprotection layer 6 and low smoke, zero halogen sheath 9 successively.
As preferred version of the present invention, fireprotection layer 6 inside of the present invention is provided with several fire guards 7 of closely arranging.
As preferred version of the present invention, cable conductors 1 of the present invention is made up of the zinc-plated same conductor lines bundle closing lay of multiply.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
