Abstract
The utility model relates to a fire -retardant cable, include by interior to outer central conductor, parcel the insulating layer of central conductor outside, parcel at the glass fiber weaving layer of insulating layer outside and the parcel sheath at glass fiber weaving layer outermost, the insulating layer is makeed with sheath adoption polyolefin flameresistant material, sheath thickness is greater than the thickness of insulating layer. Because alkene all by carbon and hydrogen element composition, only can produce water and carbon dioxide after the abundant burning, does not have harm to the human body. The product is through adopting the polyolefin as insulating and sheath, and the combination design of glass fiber tape layer shielding net, can have good fire -retardant function, still has certain waterproof function to can improve the safety in utilization of cable. The smoke and dust that produces when the burning is less and have the prevention or delay flame spread, can keep the circuit integrality to the safety of the guarantee person.
Description
Technical field
The utility model is related to electric wire field, specially a kind of flame-retardant cable.
Background technology
At present in fire incident, because the electrical fire caused by electric wire can not be ignored, in the death of fire incident
In number, 80% does not directly burn to death, but be choked to death by smog and poison gas.The dense smoke strongly diffusing makes victim distinguish
Unclear direction, dense smoke causes being at a loss of people's outbreak, thus extends in the scene of fire holdup time, makes one to be difficult to exhale
Inhale and directly fatal, the fighting and rescue operations of obstruction fire fighter simultaneously.The common electric wire in market at present, produces in burning
Flue dust more, there is hidden danger to personal safety, and water resistance have much room for improvement.
Content of the invention
The purpose of this utility model is for above-mentioned problem and shortage, provides and produces relatively during a kind of fire incident
Lack cigarette, stop or delay propagation of flame, effective waterproof, ensure the safe flame-retardant cable of the person.
The technical solution of the utility model is realized in：A kind of flame-retardant cable, including central conductor from inside to outside,
It is wrapped in the insulating barrier outside central conductor, be wrapped in the fiberglass braided layer outside insulating barrier and be wrapped in glass fibre
The outmost sheath of braiding layer, insulating barrier and sheath adopt polyolefin flame-retardant material to make, and jacket thickness is more than the thickness of insulating barrier
Degree.
Further, central conductor can be coaxial copper metal wire, and central conductor can also be and twisted by tin metal line
Close.
Further, it is additionally provided with aluminium foil layer between insulating barrier and fiberglass braided layer.
The utility model is all made up of carbon and protium due to alkene, only can produce water and titanium dioxide after fully burning
Carbon, to human body and does not endanger.Product passes through using polyolefin as insulation and sheath, and the combination of glass fibre belt gauze screen sets
Meter, can have good anti-flaming function, also have certain water-proof function, thus the safety in utilization of cable can be improved.In combustion
The flue dust producing during burning is less and has prevention or delays propagation of flame, can keep circuit integrality, to ensure the peace of the person
Entirely.
Brief description
Fig. 1 is cross section structure schematic diagram of the present utility model.
Specific embodiment
As shown in figure 1, the utility model is a kind of flame-retardant cable, including central conductor 1 from inside to outside, it is wrapped in centre
The insulating barrier 2 of wire 1 outside, it is wrapped in the fiberglass braided layer 3 of insulating barrier 2 outside and is wrapped in fiberglass braided layer
3 outmost sheaths 4, insulating barrier 2 and sheath 4 adopt polyolefin flame-retardant material to make, and sheath 4 thickness is more than the thickness of insulating barrier 2
Degree.
Central conductor 1 can be coaxial copper metal wire, and central conductor 1 can also be and formed by tin metal line is stranded
's.
The utility model another kind embodiment, is additionally provided with aluminium foil layer between insulating barrier 2 and fiberglass braided layer 3.
Embodiment above-described embodiment is the utility model preferably embodiment, but embodiment of the present utility model is not
Be restricted to the described embodiments, other any without departing from the change made under Spirit Essence of the present utility model and principle, repair
Decorations, replacement, combination, simplification, all should be equivalent substitute mode, are included within protection domain of the present utility model.
