The utility model discloses a cable still can use, catch fire when having realized the medium voltage cable conflagration gas that produces and smog nontoxic pollution -free, increase time and intelligent monitoring requirement that fire back fire control was sued and laboured for the personal safety ensures to some extent that loss of property reduces to some extent, and cable maintenance reduces with the expense of confirming the cable fault position to some extent.

Description

Middle pressure fire-resistant intellectual monitoring cable
Technical field
This utility model relates to midium voltage cable, particularly to pressing (6~35kV) fire-resistant intellectual monitoring cable in one.
Background technology
Along with the development of domestic city, economy increases rapidly, and many skyscrapers emerge in multitude.If using low pressure 0.6/1kV distribution, relatively common building thing cable consumption, lay difficulty and workload will be doubled and redoubled, and the space taken can be bigger.Employing is pressed (6~35kV) cable laying carry out distribution again in building, not only material-saving but also energy-conservation.
In skyscraper densely populated, fire once occurs, cable cannot provide electric energy to electrical equipment, certainly will make a big impact evacuating personnel, cause major casualties and property loss, therefore higher to the safety requirements rank of the midium voltage cable used in building.But existing middle pressure (the 6~35kV) fire resistance of cable, mechanical performance and intellectual monitoring performance need further to be improved, guarantee that cable can implement monitoring when overheating, and can normally use when temperature is the highest, personal injury and property loss are preferably minimized.
Utility model content
The purpose of this utility model is to provide in one presses fire-resistant intellectual monitoring cable, to solve the problems of the prior art.
To achieve these goals, the technical solution of the utility model is as follows:
Middle pressure fire-resistant intellectual monitoring cable, it is characterised in that it is characterized in that: include three insulated phase wires cores, fiber unit, flame resistant filler layer, fire-retardant band, sheath, armor and outer jacket;Described insulated phase wires core is followed successively by metallic conductor, conductor shielding, insulation, insulation shielding and metallic shield from inside to outside;Described insulation is that high dielectric crosslinked polyethylene extrudes;Described metallic shield is that high connductivity copper strips is wrapped to be formed.
In preferred embodiment of the present utility model, described fiber unit is resistant to elevated temperatures multimode temperature-measuring optical fiber, be distributed in three insulated phase wires cores stranded after gap in and symmetry be embedded in steel wire armor layer.
Further, described flame resistant filler layer is flame resistant filler rope, is filled between three insulated phase wires cores.
Further, described fire-retardant band is around the low-smoke non-halogen flame-retardant band wrapped in outside packed layer and outside armor.
Further, described sheath is that Ceramic silicon rubber fireproof oxygen-separation layer extrudes and forms.
Further, described armor is that zinc-coated wire spiral wound is outside sheath.
Further, described outer jacket is that resistant environmental low-smoke halogen-free flame polyolefin extrudes and forms.
Structure of the present utility model design and materials'use have the advantage that 1. when insulated phase wires core temperaturing lifting abnormality, then the temperature-measuring optical fiber being positioned at cable center passes temperature signal back control centre, it is possible to realize the real-time monitoring of cable internal temperature;The most when a fire, low-smoke and halogen-free flame retardant polyolefin jacket (oxygen index (OI) is 35) plays the effect of high-leveled and difficult combustion, when temperature passes to the inside, and temperature-measuring optical fiber plays a role, and passes on signal to fire fighter.And the inside is again Ceramic silicon rubber fireproof oxygen-separation layer, wins the quality time to fire-fighting and rescue again;3. use zinc-coated wire and Ceramic silicon rubber to add mechanical performance and the bending property of cable, save and lay space;4. the flame resistant filler rope of environment-friendly type instead of alkali-free glass wool and fills, it is to avoid in cable production process, alkali-free glass wool stabs skin.
Feature of the present utility model see graphic and the most preferably embodiment the detailed description of this case and obtains and be well understood to.
Accompanying drawing explanation
Fig. 1 is cross section structure schematic diagram of the present utility model.
Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be easy to understand with effect, this utility model is expanded on further below in conjunction with specific embodiment.
See Fig. 1, the one of the present embodiment is pressed (6~35kV) fire-resistant intellectual monitoring cable, including three insulated phase wires cores 1, fiber unit 2, flame resistant filler layer 3, fire-retardant band 4, sheath 5, armor 6 and outer jacket 7.Insulated phase wires core 1 is followed successively by metallic conductor 11, conductor shielding 12, insulation 13, insulation shielding 14 and metallic shield 15 from inside to outside;Insulation 13 extrudes for high dielectric crosslinked polyethylene;Metallic shield 15 forms for high connductivity copper strips is wrapped.
Concrete structure and material: metallic conductor 11 meets the regulation of GB/T 3956-2008, use Equations of The Second Kind circle to press structure;Conductor shielding 12 and insulation shielding 14 all use the semiconductive shieldin material of cross-linking type to extrude and form;The crosslinked polyethylene (XLPE) of the insulation 13 high dielectric of employing;Metallic shield 15 uses the copper strip shielding of high connductivity;Fiber unit 2 uses resistant to elevated temperatures multimode temperature-measuring optical fiber;Be distributed in three insulated phase wires cores stranded after gap in and symmetry be embedded in steel wire armor layer.Flame resistant filler layer 3 uses the flame resistant filler rope of environment-friendly type, is filled between three insulated phase wires cores 1.Fire-retardant band 4 uses the low-smoke non-halogen flame-retardant band of environment-friendly type, around wrapping in outside packed layer 3 and outside armor 6.Sheath 5 uses Ceramic silicon rubber fireproof oxygen-separation layer;Armor 6 uses zinc-coated wire;Outer jacket 7 uses resistant environmental low-smoke halogen-free flame polyolefin (oxygen index (OI) is 35) high nonflammable material.
Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.Skilled person will appreciate that of the industry; this utility model is not restricted to the described embodiments; simply principle of the present utility model described in above-described embodiment and description; on the premise of without departing from this utility model spirit and scope, this utility model also has various changes and modifications, and these changes and improvements both fall within the range of claimed this utility model.The protection domain that this utility model requires is defined by appending claims and equivalent thereof.
