Description
Technical field
The utility model relates to electric field more particularly to a kind of fire-fighting system flame-retardant low-smoke halogen-free fire-resisting cables.
Background technique
Cable is electric power required in our present social life, and conveying uses the material that can all use, no electricity
Cable electric power can not just convey, and also not be available, and the power supply line that present fire-fighting uses is nonflammable, prevent fire spreading, effectively prolong
Long ventilation, illumination, alarm system working time.Even if burning, the smog of generation is few, and smog is free of " fluorine, chlorine, bromine, iodine, astatine "
Element (toxic, with irritant) is fire-fighting and rescue when fire occurs because the product belongs to fire-retardant, low cigarette, Halogen feature
It gains time, and general fire incident is that toxic smog is smoked dead, which belongs to low smoke and non-toxic, rescues for personnel escape and fire-fighting
It helps and gains time.
Utility model content
It is above-mentioned to solve the purpose of this utility model is to provide a kind of fire-fighting system flame-retardant low-smoke halogen-free fire-resisting cable
Technical problem, the utility model uses following technical scheme to achieve the above object:
A kind of fire-fighting system flame-retardant low-smoke halogen-free fire-resisting cable, including air contact layer, filled layer, inside conductor group, institute
It states filled layer to be full of around inside conductor group, the air contact layer is wrapped on the outside of inside conductor group and filled layer, the air
Contact layer is made of shielded layer, external insulation layer, and the shielded layer is wrapped in the outside of external insulation layer, and the inside conductor group is by three
Identical conducting wire composition, the conducting wire are made of core, inner insulating layer, mica tape, and the mica tape is wrapped on the outside of core, institute
Inner insulating layer is stated to be wrapped on the outside of mica tape and core.
On that basis of the above technical scheme, the mica tape is made of fireproof mica material, and the core is by metallic copper wire
It is made, the filled layer is made of adhesive tape and rope made of hemp mixed weaving, and talcum powder and the mixing filling of cable special magnesium oxide, described
Shielded layer is made of electrician's soft copper silk, and the external insulation layer and inner insulating layer are made of nylon PAGF material.
Compared with prior art, the utility model has the advantage that the utility model benefit had both optimized fire-fighting and used system
The design of cable changes the design of traditional cable, improves the fire resistance of cable, increases service life, designed mica tape
It can to ensure that the core inside power supply line will not be exposed in fire incident, electric leakage accident will not occur to add evil event
Seriousness, in addition insulating layer used by equipment is that the modeling prepared material of flame-retardant low-smoke halogen-free is securely and reliably preferably promoted the use of.
Detailed description of the invention
Fig. 1 is the state diagram of the utility model overall appearance.
Fig. 2 is the utility model cross-section of cable floor map.
Fig. 3 is the utility model individual conductor sectional plane schematic diagram.
In figure: 1- air contact layer, 2- inside conductor group, 3- conducting wire group, 4- shielded layer, 5- external insulation layer, 6- conducting wire, 7- line
Core, 8- inner insulating layer, 9- mica tape.
Specific embodiment
The utility model is further elaborated in the following with reference to the drawings and specific embodiments.
A kind of fire-fighting system flame-retardant low-smoke halogen-free fire-resisting cable, including air contact layer 1, filled layer 2, inside conductor group 3,
The filled layer 2 is full of around inside conductor group 3, and the air contact layer 1 is wrapped in 2 outside of inside conductor group 3 and filled layer, institute
It states air contact layer 1 to be made of shielded layer 4, external insulation layer 5, the shielded layer 4 is wrapped in the outside of external insulation layer 5, described interior
Conducting wire group 3 is made of three identical conducting wires 6, and the conducting wire 6 is made of core 7, inner insulating layer 8, mica tape 9, the mica
Band 9 is wrapped in 7 outside of core, and the inner insulating layer 8 is wrapped in 7 outside of mica tape 9 and core.
The mica tape 9 is made of fireproof mica material, and the core 7 is made of metallic copper wire, and the filled layer 2 is by glue
Item and rope made of hemp mixed weaving are made, and talcum powder and the mixing filling of cable special magnesium oxide, and the shielded layer 4 is by electrician's soft copper silk
It is made, the external insulation layer 5 and inner insulating layer 8 are made of nylon PA66GF material.
Utility model works principle: the inner insulating layer and external insulation layer of such cable, which play, ensures internal power transmission,
The case where electric leakage will not being generated to the external world, while external insulation layer plays the effects of antifriction, sun-proof, corrosion-resistant, fire-retardant, is fire-fighting
Time reinforcement is played the role of in rescue, and filled layer plays the friction between inner lead group and protective layer, can reduce and rub
It wipes and the heat generated and abrasion, the effect of shielded layer is played the electric power that internal power transmission will not incude near cable and passed
Defeated and bring electromagnetic field or inside and outside rub caused by electrostatic to carry out damage cable etc. a series of damages.
The above is the utility model preferred embodiment, for the ordinary skill in the art, according to this reality
With novel introduction, in the case where not departing from the principles of the present invention and spirit, the change that is carried out to embodiment is repaired
Change, replacement and variant is still fallen within the protection scope of the utility model.
