Abstract
The utility model is related to a kind of safe cotton covered wire of Novel firefighting, including conductor, insulating layer is coated on the outside of conductor, the outside of insulating layer coats shielded layer, and the outside of shielded layer is equipped with protective layer；Shielded layer is the copper strips lapping layer being coated on by wrapped mode on the outside of insulating layer.The shielded layer of the electric wire is using copper strips wrapping concentric conductor structure as zero curve (cathode); conductor is firewire (anode); outer layer extrude halogen-free and low-smoke flame-retardant polyolefin be external protection, be produced into while having fire prevention, fire-retardant, shielding action and firewire, zero curve consubstantiality structure security against fire type cotton covered wire.Internally inorganic insulation layer generates protection to copper strips lapping layer (zero curve copper conductor), under Fire Conditions, continues to electric power.Simultaneously as being zero curve and firewire consubstantiality structure, primary threading can realize power circuit, save the construction time and reduce quantities.Copper strips lapping layer can play the role of mechanical protection with inner conductors and insulating layer.
Description
Technical field
The use of the new type belongs to technical field of electric wires and cables, especially a kind of safe cotton covered wire of Novel firefighting.
Background technology
Existing cotton covered wire (BV, RV series), insulation is all to use PVC (polyvinyl chloride).The material contains halogen, right
Environment be easy to cause pollution.Under Fire Conditions, a large amount of halide-containings (HCl) can be released, huge corrosion is generated to article,
Skin and respiratory tract to personnel generate huge injury.And common fire resisting cotton covered wire, under Fire Conditions, outer layer is due to fire resisting
The weary effective protection of break, is also easy to produce ground short circuit.
Meanwhile existing cotton covered wire generally use single cable installation in pipe, occupied space is larger, and cable laying operation amount compared with
Greatly.
Utility model content
Purpose of the utility model is to solve defects of the existing technology, provide a kind of safe cloth electricity of Novel firefighting
Line.
To achieve the goals above, the technical solution adopted in the utility model is：
A kind of safe cotton covered wire of Novel firefighting, including conductor, conductor outside coat insulating layer, the outside cladding screen of insulating layer
Layer is covered, the outside of shielded layer is equipped with protective layer；
The shielded layer is to be coated on the copper strips lapping layer on the outside of insulating layer, copper strips lapping layer zero by wrapped mode
Line conductor, the conductor are firewire conductor.
Further, the material of the conductor is copper.
Further, the insulating layer is the mica tape on the outside of conductor, and cap rate is not less than 25%.
Further, the material of the protective layer is low smoke halogen-free flame-retardant polyolefin.
Further, the protective layer is arranged by way of extruding in the outside of shielded layer.
Further, the conductor is solid conductor or stranded conductor.
Further, the copper strips section of the copper strips lapping layer is not less than cross-sectional area of conductor, and cap rate is not less than 10%.
The beneficial effects of the utility model are：The shielded layer of the electric wire is using copper strips wrapping concentric conductor structure as zero curve
(cathode), conductor are firewire (anode), and it is external protection that outer layer, which extrudes halogen-free and low-smoke flame-retardant polyolefin, is produced into while having anti-
The security against fire type cotton covered wire of fiery, fire-retardant, shielding action and firewire, zero curve consubstantiality structure.
The patented technology, internally inorganic insulation layer generates protection to copper strips lapping layer (zero curve copper conductor), under Fire Conditions,
Continue to electric power.Simultaneously as being zero curve and firewire consubstantiality structure, primary threading can realize that power circuit, saving are applied
Between working hour and reduce quantities.In addition, copper strips lapping layer can play the role of mechanical protection (as in vain with inner conductors and insulating layer
Ant, mouse bite).
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail with specific implementation mode with reference to the accompanying drawings of the specification.
As shown in Figure 1, a kind of safe cotton covered wire of Novel firefighting, including conductor 1,1 outside of conductor coat insulating layer 2, insulation
The outside of layer 2 coats shielded layer 3, and the outside of shielded layer 3 is equipped with protective layer 4；
Shielded layer 3 is the copper strips lapping layer that 2 outside of insulating layer is coated on by wrapped mode, and copper strips lapping layer is zero curve
Conductor, conductor 1 are firewire conductor.
Wherein, the material of conductor 1 is copper, and insulating layer 2 is the mica tape on the outside of conductor, and cap rate is not less than
25%, the material of protective layer 4 is low smoke halogen-free flame-retardant polyolefin, and protective layer 4 is arranged by way of extruding in the outer of shielded layer 3
Side.
Conductor 1 is solid conductor or stranded conductor, and the copper strips section of copper strips lapping layer is not less than 1 section of conductor, puts up
Rate is not less than 10%.
The shielded layer 3 of the electric wire is used as zero curve (cathode) using copper strips wrapping concentric conductor structure, conductor 1 for firewire (just
Pole), outer layer extrude halogen-free and low-smoke flame-retardant polyolefin be external protection 4, be produced into while having fire prevention, fire-retardant, shielding action and
The security against fire type cotton covered wire of firewire, zero curve consubstantiality structure.
The patented technology, internally inorganic insulation layer 2 generates protection to copper strips lapping layer (zero curve copper conductor), in Fire Conditions
Under, continue to electric power.Simultaneously as being zero curve and firewire consubstantiality structure, primary threading can realize power circuit, save
Construction time and reduction quantities.In addition, copper strips lapping layer can play the role of mechanical protection (such as with inner conductors and insulating layer
Termite, mouse bite).
Obviously, those skilled in the art can carry out the utility model various modification and variations without departing from this practicality
Novel spirit and scope.If in this way, these modifications and variations of the present invention belong to the utility model claims and
Within the scope of its equivalent technology, then the utility model is also intended to include these modifications and variations.
