Description
【Technical field】
It the utility model is related to a kind of cable, more particularly to a kind of polyvinyl chloride insulation flame retardant cable.
【Background technology】
With the development of society, power transmission has infiltrated through the every aspect of our lives, with power transmission technology
Development, the power cable of various functions are also developed and applied.For common cable, power transmission is typically only taken into account
Can, it seldom can take into account anti-flammability.And for the special flame retardant cable or fire-resisting cable being related to, and because its cost is too high, it is impossible to
Generally use.Therefore research and development one kind had both met power transmission requirement, and can has anti-flammability, makes in case of fire, can be
Burning is limited in subrange, does not produce sprawling, the flame retardant cable for avoiding resulting in greater loss just becomes necessary.
【Utility model content】
The problem of to overcome existing cable anti-flammability bad, it is exhausted that the utility model provides a kind of polyvinyl chloride of good flame resistance
Edge flame retardant cable.
The technical scheme that the utility model solves technical problem is to provide a kind of polyvinyl chloride insulation flame retardant cable, including more
Individual conductor, multiple conductor outer cladding polyvinyl chloride insulation layers, polyvinyl chloride insulation layer outer cladding flame-proof PVC inner sheath are multiple to lead
Body and coat its outside flame-proof PVC inner sheath outer cladding inner liner, flame resistant filler is set between inner liner and flame-proof PVC inner sheath
Material, inner liner outer cladding steel-tape armouring layer, steel-tape armouring layer outer cladding flame-proof PVC oversheath, the interior setting of flame-retardant filler are multiple
Fire extinguishing rope, fire extinguishing rope include rope outer cover of putting out a fire, powder extinguishing agent are filled in fire extinguishing rope outer cover, and fire extinguishing rope is cylinder, and every meter is somebody's turn to do
Fire extinguishing rope quantity is set to be no less than 2 in polyvinyl chloride insulation flame retardant cable.
Preferably, hollow out forms cavity inside the flame-proof PVC inner sheath and flame-proof PVC oversheath, and resistance is filled in cavity
Agent is fired, fire retardant is aluminium hydroxide fire retardant.
Preferably, the flame-retardant filler is montmorillonite or diatomite.
Compared with prior art, a kind of polyvinyl chloride insulation flame retardant cable provided by the utility model, hindered by setting
PVC inner sheaths and flame-proof PVC oversheath are fired, iris action twice can be played to the condition of a fire, fire spreading can be effectively prevented, to electricity
Cable internal structure plays a protective role.In addition, the utility model polyvinyl chloride insulation flame retardant cable is by setting fire extinguishing rope, can be with
The effect put out is played to the intensity of a fire for spreading to inside, further strengthens the fire resistance of cable.
【Brief description of the drawings】
Fig. 1 is the utility model polyvinyl chloride insulation flame retardant cable structural representation；
Fig. 2 is the utility model polyvinyl chloride insulation flame retardant cable fire extinguishing rope structure schematic diagram；
In figure：Conductor 1, polyvinyl chloride insulation layer 2, flame-proof PVC inner sheath 3, flame-retardant filler 4, inner liner 5, steel band armour
Fill layer 6, flame-proof PVC oversheath 7, fire extinguishing rope 8, fire extinguishing rope outer cover 81, powder extinguishing agent 82.
【Embodiment】
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only solving
The utility model is released, is not used to limit the utility model.
Referring to Fig. 1, the polyvinyl chloride insulation flame retardant cable described by the utility model, including multiple conductors 1, conductor 1
Outer cladding polyvinyl chloride insulation layer 2, the outer cladding flame-proof PVC inner sheath 3 of polyvinyl chloride insulation layer 2, multiple conductors 1 and coat its outside
The outer cladding inner liner 5 of flame-proof PVC inner sheath 3, between inner liner 5 and flame-proof PVC inner sheath 3 set flame-retardant filler 4.Liner
5 outer cladding steel-tape armouring layer 6 of layer, the outer cladding flame-proof PVC oversheath 7 of steel-tape armouring layer 6.Multiple go out is set in flame-retardant filler 4
Rope of plaited plants 8, fire extinguishing rope 8 include rope outer cover 81 of putting out a fire, and powder extinguishing agent 82, the thickness of fire extinguishing rope outer cover 81 are filled in fire extinguishing rope outer cover 81
Degree is not more than 2mm.When inside fire spreading to cable, fire extinguishing rope outer cover 81 ruptures, and powder extinguishing agent 82 rushes out of fire extinguishing rope 8
Go out, can effectively put out the condition of a fire, prevent fire spreading.Fire extinguishing rope 8 is cylinder, and diameter is more than or equal to 10mm, it is ensured that inside it
Enough powder extinguishing agents 82 are filled, effectively put out the condition of a fire.Fire extinguishing 8 quantity of rope are set in every meter of polyvinyl chloride insulation flame retardant cable
No less than 2.
Wherein, flame-proof PVC inner sheath 3 and the inside hollow out of flame-proof PVC oversheath 7 form cavity (not shown), are filled out in cavity
Fire retardant is filled, can effectively prevent the condition of a fire from being spread to cable inside when a fire starts and spreads.Wherein the thickness of cavity is more than or equal to 3mm, really
Guarantor can store enough fire retardants.Fire retardant is aluminium hydroxide fire retardant, and flame-retardant filler 4 is montmorillonite or diatomite.
Compared with prior art, a kind of polyvinyl chloride insulation flame retardant cable provided by the utility model, hindered by setting
PVC inner sheaths 3 and flame-proof PVC oversheath 7 are fired, iris action twice can be played to the condition of a fire, can effectively prevent fire spreading, it is right
Cable internal structure plays a protective role.In addition, the utility model polyvinyl chloride insulation flame retardant cable by set fire extinguishing rope 8,
The effect put out can be played to the intensity of a fire for spreading to inside, further strengthen the fire resistance of cable.
Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model
Any modification made within the principle of utility model, equivalent substitution and improvement etc. all should include the scope of protection of the utility model
Within.
