Description
Technical field
It the utility model is related to a kind of cotton covered wire, more particularly to a kind of high flame resistance, low smoke halogen-free nylon sheath fire- resistance cloth electricity
Line.
Background technology
Common fire-resistant wires are the mica tape of wrapped a layer thickness 0.014mm to 0.016mm on copper conductor, outer to squeeze
A layer insulating is wrapped, more single lines are combined into additional sheath, insulating barrier and oversheath use high flame resistance, low smoke Halogen material.
Because insulating barrier is comparatively thicker, the weight of whole cable is also heavier, and when sheath is coated using squash type, such as absolutely
Do not added between edge layer and oversheath separation layer or separation layer addition it is uneven can produce insulating barrier and sheath adhesion phenomenon,
Subsequent clients are caused to use difficult.
The content of the invention
The purpose of this utility model is to provide a kind of high flame resistance, low smoke halogen-free nylon sheath fire resisting cotton covered wire, the cotton covered wire
Nylon inner sheath is employed, electric wire weight can be mitigated, reduces use cost.
In order to realize above-mentioned technical purpose, the utility model adopts the following technical scheme that：
A kind of high flame resistance, low smoke halogen-free nylon sheath fire resisting cotton covered wire, including conductor, mica tape, insulating barrier, sheath, it is described
Wrapped mica tape outside conductor, the outer extruded insulation layer of mica tape, insulating barrier is high flame resistance, low smoke Halogen material；Extruded outside the insulating barrier
For inner sheath as cored wire, inner sheath is fire-retardant nylon；It is outer after split conductor stranding to extrude oversheath, oversheath be high flame resistance, low smoke without
Halogen material.
The fire-retardant nylon thickness is 0.08mm~0.10mm.
Described Mica tape a layer thickness is 0.010mm~0.012mm.
The utility model high flame resistance, low smoke halogen-free nylon sheath fire resisting cotton covered wire employs nylon inner sheath, is not changing electricity
In the case of linear energy, the thickness of insulation can be reduced 30%~40% on the basis of original, whole cable weight can be mitigated,
The use of material is reduced, further reduces cable cost.And the mechanical performance and oil resistivity of cotton covered wire are enhanced.
Nylon surface smoother, it is not easy to produce to glue with oversheath and take phenomenon, can be without using separation layer；Meanwhile insulating barrier, interior shield
Set and oversheath use flame-retardant materials, and the flame-retardant of whole cable has also obtained very big lifting.
The utility model high flame resistance, low smoke halogen-free nylon sheath fire resisting cotton covered wire is applied to use on building building.
Brief description of the drawings
Fig. 1 is the utility model high flame resistance, low smoke halogen-free nylon sheath fire- resistance cloth wire structure schematic diagram.
In figure：1 conductor, 2 mica tapes, 3 insulating barriers, 4 inner sheaths, 5 oversheaths.
Embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Referring to Fig. 1, a kind of high flame resistance, low smoke halogen-free nylon sheath fire resisting cotton covered wire, including conductor 1, mica tape 2, insulating barrier
3rd, inner sheath 4, oversheath 5；
The conductor 1 uses bare copper wire, wrapped mica tape 2 outside conductor 1, Mica tape a layer thickness be 0.010mm~
0.012mm；Being burnt according to fire resisting, grade is different, and the wrapped number of plies of mica tape is also different, in the case where not changing cable performance
Using thin mica tape can suitably reduce it is wrapped after external diameter.
The outer extruded insulation layer 3 of mica tape 3, insulating barrier 3 are high flame resistance, low smoke Halogen material, are extruded outside the insulating barrier 3
Inner sheath 4 is used as cored wire；Inner sheath is fire-retardant nylon, and fire-retardant nylon thickness is 0.08mm~0.10mm；Make it to inhale well
The surface of insulating barrier 3 is attached to, the separation that can cause to flake between both materials influences properties of product as nylon is blocked up.
Outer after split conductor stranding to extrude oversheath 5, oversheath 5 is high flame resistance, low smoke Halogen material.The cotton covered wire cross section
For flat.
The utility model high flame resistance, low smoke halogen-free nylon sheath fire resisting cotton covered wire due to having extruded one layer of nylon inner sheath,
In the case of not changing electric wire performance, the thickness of insulation can be reduced 30%~40% on the basis of original, whole can be mitigated
Cable weight, the use of material is reduced, further reduces cable cost；Nylon, the mechanical performance and oil resistivity of electric wire are extruded
Be greatly improved, nylon surface smoother, it is not easy to oversheath produce it is viscous take phenomenon, can without using separation layer,
Meanwhile insulation is strange, inner sheath and oversheath use flame-retardant materials, the flame-retardant of whole cable has also obtained carrying greatly very much
Rise.
Preferred embodiment of the present utility model is these are only, is not intended to limit the scope of protection of the utility model,
Therefore, all made within spirit of the present utility model and principle any modification, equivalent substitution and improvements etc., should be included in
Within the scope of protection of the utility model.
