In prior art, cotton covered wire typically uses polrvinyl chloride as insulation.This cotton covered wire is owing to its construction features is with exhausted
Edge Flame Retardancy can limit, and bunchy fire resistance can only pass through GB/T18380B class, it is impossible to passes through GB31247B1Level.At fire
When calamity occurs, the cotton covered wire that bunchy lays once burns, and prolongs combustion distance, and burning produces amount of heat and cigarette, can aggravate fire
Harm, it is difficult to strive for the longer time for escape and rescue.And low-smoke halogen-free polyolefin insulating cotton covered wire due to use low cigarette without
Halogen polyolefin, as insulation, solves the problem that smoke-producing amount when catching fire is the biggest, but flame retardant effect still can only pass through GB/
T18380B class, it is impossible to pass through GB31247B1Level.Low-smoke halogen-free polyolefin material with the addition of a large amount of magnesium hydroxide, hydrogen-oxygen simultaneously
Changing aluminum fire retardant, macromolecular chain binding strength is deteriorated, and between macromolecular chain, gap becomes big, and the mechanical performance of material is substantially reduced (draws
Stretch intensity and only have 10MPa), water penetration is greatly increased, and about reduces by two numbers than PVC electric wire insulation resistance after electric wire immersion
Magnitude.And existing electric wire heat dispersion is poor, is not easy to fix when many electric wires are put together.
Utility model content
The technical problem existed based on background technology, the utility model proposes a kind of embedded glass braiding fire retardant electricity
Line.
The one embedded glass braiding fire retardant electric wire that the utility model proposes, gathers including core, low-smoke non-halogen flame-retardant
Alkene insulating barrier and glass fibre embeding layer；
Low smoke halogen-free flame-retardant polyolefin insulating barrier is coated on core, and glass fibre embeding layer is embedded in low-smoke non-halogen flame-retardant
In polyolefin insulation layer, and it is positioned at low smoke halogen-free flame-retardant polyolefin insulating barrier edge.
Preferably, described embedded glass braiding fire retardant electric wire also includes multiple assembled layers；
Assembled layers includes many first fasteners and multiple second fastener, and the shape of the first fastener and the second fastener can
Dismounting coordinates, and the first fastener and the second fastener are arranged on glass fibre embeding layer periphery；
Assembled layers axially sets gradually along glass fibre embeding layer.
Preferably, the first fastener be two along axially arranged the first elastic projection of glass fibre embeding layer, any one
Individual first post is provided with gear projection near the side of another post, and lattice gear projection is positioned at the first elastic projection away from line
The side of core, the second fastener is along axially arranged the second elastic projection of glass fibre embeding layer, the second elastic projection away from
Core is provided with and snaps in post, snaps in post for cylinder.
Preferably, in any one assembled layers, the first fastener and the second fastener are along between glass fibre embeding layer circumference
Every distribution.
Preferably, the spacing between the assembled layers that any two is adjacent is equal.
Preferably, glass fibre embeding layer periphery scribbles heat discoloration coating.
This utility model glass fibre that once catches fire can stop flame high temperature so that insulating barrier fire area reduces, burning
Reaction is suppressed significantly；Have and tested by GB/T18380 the highest classification A class, also can pass through GB31247B1Level, good flame resistance,
The features such as dielectric strength is high, poling is convenient, water resistance is good, burning heat production smoke-producing amount is little, can meet important events fire-resistant wire
Need, and this utility model simple in construction, it is simple to manufacture and use.
Accompanying drawing explanation
Fig. 1 is that the embedded glass of the one that the utility model proposes weaves fire retardant wire structure schematic diagram.
Detailed description of the invention
With reference to shown in Fig. 1, the one embedded glass braiding fire retardant electric wire that the utility model proposes, including core 1, low
Cigarette halogen-free anti-flaming polyolefin insulating barrier 2, glass fibre embeding layer 3 and multiple assembled layers 4；
Low smoke halogen-free flame-retardant polyolefin insulating barrier 2 is coated on core 1, and glass fibre embeding layer 3 is embedded in low smoke and zero halogen
In fire retardant polyolefin insulating barrier 2, and it is positioned at low smoke halogen-free flame-retardant polyolefin insulating barrier 2 edge.
Core 1 when making, metal is carried out wire drawing, to described wire drawing metal anneal；Core 1 extrudes low smoke and zero halogen
Fire retardant polyolefin insulating barrier 2；At low smoke halogen-free flame-retardant polyolefin insulating barrier 2 outer braided glass fibre embeding layer 3 and embed low cigarette
Halogen-free anti-flaming polyolefin insulating barrier 2 i.e. can be made into this embedded glass braiding fire retardant electric wire.
Assembled layers 4 includes many first fasteners 41 and multiple second fastener 42, the first fastener 41 and the second fastener
The shape of 42 detachably coordinates, and the first fastener 41 and the second fastener 42 are arranged on glass fibre embeding layer 3 periphery.
Assembled layers 4 axially sets gradually along glass fibre embeding layer 3.Assembled layers 4 effectively increases this embedded glass and compiles
Knit fire retardant electric wire area of dissipation, improve this embedded glass braiding fire retardant electric wire radiating effect, any two assembled layers 4
Between space can the space of air circulation, improve further this embedded glass braiding fire retardant electric wire radiating effect.
In present embodiment, the first fastener 41 be two along axially arranged first elastic convex of glass fibre embeding layer 3
Post, any one first post is provided with gear projection near the side of another post, and it is elastic that lattice gear projection is positioned at first
