Description
Technical field
This utility model relates to power cable field, is specifically related to a kind of low-smoke non-halogen flame-retardant fire prevention
Power cable.
Background technology
Along with rapid development of economy, increasing people pours into big city so that metropolitan
Traffic congestion phenomenon becomes increasingly severe.In order to effectively solve the traffic congestion in city, each greatly
The engineering such as subway, light rail is all being developed energetically in city, these engineerings build and use
During, can use substantial amounts of power cable, and these engineering locations, population is the most non-
It is the most intensive, if initiation fire or extraneous burning things which may cause a fire disaster cause owing to the security performance of power cable is not enough
The burning of power cable, its consequence will be hardly imaginable.
Utility model content
For defect present in prior art, the purpose of this utility model is to provide a kind of low
Cigarette halogen-free flameproof fire proof power cable, has good fire-retardant and fire protecting performance.
For reaching object above, this utility model adopts the technical scheme that: including: cable core,
Described cable core includes many conductors, and is enclosed with fire-resistant on every conductor the most successively
Layer, insulating barrier, described cable core is enclosed with sheath, armor, resistance the most successively
Fire layer, between outer jacket, and sheath and cable core, be filled with insulant.
On the basis of technique scheme, the insulant between described sheath and cable core is
Glass cord.
On the basis of technique scheme, the conductor in described cable core is many stranded leading
Line.
On the basis of technique scheme, described flame retardant coating is mica tape.
On the basis of technique scheme, the material of described insulating barrier is mineral insulation material.
On the basis of technique scheme, the material of described insulating barrier is magnesium oxide.
On the basis of technique scheme, the material of described sheath is low smoke and zero halogen polyene
Hydrocarbon.
On the basis of technique scheme, described armor is spiral copper strips.
On the basis of technique scheme, described flame-retardant layer is low-smoke non-halogen flame-retardant band.
On the basis of technique scheme, the material of described outer jacket is low smoke and zero halogen polyene
Hydrocarbon.
Compared with prior art, the utility model has the advantage of: electric power of the present utility model electricity
Cable uses flame retardant coating and the dual fire proof construction of flame-retardant layer so that cable entirety has stronger preventing
Fire performance, safety coefficient is high, significantly reduces the unnecessary loss brought because of fire.
Accompanying drawing explanation
Fig. 1 is the sectional view of this utility model a kind of low-smoke non-halogen flame-retardant fire proof power cable.
In figure: 1-cable core, 2-conductor, 3-flame retardant coating, 4-insulating barrier, 5-insulant, 6-
Sheath, 7-armor, 8-flame-retardant layer, 9-outer jacket.
Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
Shown in Figure 1, this utility model provides a kind of low-smoke non-halogen flame-retardant fire prevention electric power electricity
Cable, including being positioned at the cable core 1 at power cable center, cable core 1 includes many stranded leading
Body 2, is typically formed by 3 conductors 2 are stranded, and conductor 2 is formed by multiple conducting wires is stranded, and
Being enclosed with flame retardant coating 3, insulating barrier 4 on every conductor 2 the most successively, flame retardant coating 3 is adopted
Wrapped forming with mica tape is overlapping on conductor 2, insulating barrier 4 uses mineral insulation material resistance to
Extruding composition on fire bed 3, mineral insulation material is generally magnesium oxide.
Be enclosed with the most successively on cable core 1 sheath 6, armor 7, flame-retardant layer 8,
Insulant 5 it is filled with, this insulant 5 between outer jacket 9, and sheath 6 and cable core 1
Generally glass cord；Sheath 6 is extruded by low-smoke halogen-free polyolefin and constitutes；Armor 7
By copper strips, on sheath 6, spiral is wrapped constitutes, thus forms spiral copper strips, improves
The anticollision performance of whole power cable；Flame-retardant layer 8 uses low-smoke non-halogen flame-retardant band at armor
On 7, overlapping wrapped composition, improves the fire protecting performance of power cable, effectively prevent because of fire
And the safety problem caused；Outer jacket 9 is extruded system by low-smoke halogen-free polyolefin on flame-retardant layer 8
Becoming, certainly, outer jacket 9 can also use low smoke and zero halogen anti-ultraviolet polyolefine material, improves
The ultraviolet resistance of cable.Power cable of the present utility model, uses flame retardant coating 3 and fire-retardant
The dual fire proof construction of layer 8 so that whole cable has good fire protecting performance, safety is high.
This utility model is not only limited to above-mentioned preferred forms, and anyone is at this utility model
Enlightenment under all can draw other various forms of products, no matter but in its shape or structure make
Any change, every have same or like with this utility model as technical scheme, all at it
Within protection domain.
