Caused by barrier or cable traffic overload cause cable fire to spread.Traditional control cable insulation material selects polychlorostyrene second mostly
Alkene, although its flame retardant property is preferable, since the material combustion process generates the pernicious gases such as a large amount of cigarette and hydrogen chloride, thus
The life security of people is seriously threatened, therefore cable fire can generate a large amount of flue dust and toxicity that is irritating to human body and anaesthetizing
Gas, these flue dust and poisonous gas are first is that cause the reduction of scene of a fire visibility, so that influencing personnel flees from the scene of a fire, second is that causing people
Member room breath, poisoning are even dead.Therefore no matter from the angle of security against fire, or research and development one are required from the point of view of environmental protection
Kind environmental-protection flame-retardant shielding control cable.
Utility model content
A kind of environmental-protection flame-retardant shielding control electricity is provided the purpose of the utility model is to overcome the defect of the prior art
Cable, it has the excellent properties such as fire-retardant, low cigarette, low toxicity, moisture-proof, anti-corrosion and antisitic defect.
Purpose of the utility model is realized as follows: a kind of environmental-protection flame-retardant shielding controls cable, including more are placed in
The insulated wire cores of cable center, a plurality of insulated core are twisted into round cable core together with packing material, be followed successively by outside cable core band,
Inner sheath, armor and oversheath；Wherein,
The every insulated wire cores include single solid conductors and the insulating layer that is extruded in outside conductor, the thickness of the insulating layer
For 0.6~0.7mm and use crosslinked polyethylene insulation material；
The high fire-retardance glass cloth tape that the band uses with a thickness of 0.17mm, and by 15~20% Duplication around institute
It states outside cable core；
Shielded layer is also set up between the band and inner sheath, the shielded layer is two-way by the count of setting by soft copper silk
It is cross-woven, shielded layer system packet is outside the band；
The armor uses the double-deck galvanized steel strip and presses the clearance rate set in a manner of gap around the interior shield
Set is outer；
The oversheath is using halogen-free and low-smoke flame-retardant polyolefin material and is extruded in outside the armor.
Above-mentioned environmental-protection flame-retardant shielding control cable, wherein the diameter of the soft copper silk is 0.2mm；The braiding is close
Degree is greater than 80%.
Above-mentioned environmental-protection flame-retardant shielding control cable, wherein every layer of galvanized steel strip with a thickness of 0.2~0.5mm,
The clearance rate is 45~50%.
The environmental-protection flame-retardant shielding control cable of the utility model has the following characteristics that
1, insulating layer selects crosslinked polyethylene insulation material, will not generate poisonous gas in burning, and after stranding
Cable core external application high fire-retardance glass cloth tape is wrapped as band, and oversheath selects halogen-free and low-smoke flame-retardant polyolefin material, to make whole
Root cable can achieve the effect that burning velocity that is fire-retardant, and reducing cable, and the intensity of a fire is prevented further to spread；
2, the proof copper-wire braided that shielded layer is wrapped using system, this shielding construction can make electric field shielding in the inside of cable core, eliminate
To extraneous interference, and the mechanical force of a part can be born.In addition diameter can be played by steel-tape armouring layer being added between inner/outer sheath
To booster action, prevent cable from being influenced work by external mechanical damage.
Detailed description of the invention
Fig. 1 is the sectional view of the environmental-protection flame-retardant shielding control cable of the utility model.
Specific embodiment
Below in conjunction with attached drawing, the utility model is described in further detail.
Referring to Fig. 1, the environmental-protection flame-retardant shielding control cable of the utility model, is placed in the exhausted of cable center including more
Edge core, a plurality of insulated core and packing material 3, which rise, is twisted into round cable core, and band 4, shielded layer 5, interior shield are followed successively by outside cable core
Set 6, armor 7 and oversheath 8；Wherein,
Every insulated wire cores include single solid conductors 1 and the insulating layer 2 that is extruded in outside conductor 1, the thickness of the insulating layer 2
For 0.6~0.7mm and use crosslinked polyethylene insulation material；
Band 4 is using the high fire-retardance glass cloth tape with a thickness of 0.17mm and by 15~20% Duplication around cable core
Outside；
Shielded layer 5 is woven by the soft copper silk that diameter is 0.2mm by the count greater than 80% is bidirectional crossed, the screen
The system packet of layer 5 is covered outside band 4；
Armor 7 use bilayer thickness be the galvanized steel strip of 0.2~0.5mm and by clearance rate in the way of 45~50%
Gap is outside inner sheath 6；
Oversheath 8 is using halogen-free and low-smoke flame-retardant polyolefin material and is extruded in outside armor 7.
The environmental-protection flame-retardant shielding control cable of the utility model has the following characteristics that
1, the design of environmental-protection flame-retardant structure
The insulating layer of the utility model selects crosslinked polyethylene insulation material, but crosslinked polyethylene insulation material is not fire-retardant
Performance, so structure design must be adjusted, so that it is fire-retardant to enable whole cable to achieve the effect that.In order to reduce the burning speed of cable
Degree prevents the intensity of a fire from further spreading, and the cable core external application high fire-retardance glass cloth tape after stranding is wrapped as band.High fire-retardance glass
Strap can resolve into metal oxide after meeting fire and the crystallization water is precipitated.Metal oxide forms reticular structure after decomposing, to flue gas
There is certain suction-operated.And the crystallization water being precipitated not only plays apparent settlement action to soot, but also has preferable
Endothermic effect.Furthermore carbonized structure can be formed in combustion, and this carbonized structure is sent out at the low cigarette of cable, fire-retardant aspect
Huge effect has been waved, burning velocity when heat-absorbing action energy delay cable itself starts burning and the time steeply risen, by
In the formation of carbonized structure, to hinder the supply of oxygen and the flowing of fuel gas, therefore the burning of cable has been resisted.This
Outside, in order to ensure better flame retardant effect, oversheath select halogen-free and low-smoke flame-retardant polyolefin material, which can not only play resistance
Fuel efficiency fruit, while there is the performance of Halogen, low cigarette, it arranges in pairs or groups and uses with high fire-retardance glass cloth tape, the effect of environmental protection flame retardant can be played.
2, the design of anti-interference antisitic defect structure
Shielded layer is used as using system coppered wire braiding, this shielding construction can make electric field shielding in the inside of cable core, eliminate
To extraneous interference, and the mechanical force of a part can be born.In addition steel-tape armouring layer is added between inner/outer sheath, can play
Radial booster action prevents cable from being influenced work by external mechanical damage.
Above embodiments are only for illustration of the utility model, rather than limitations of the present invention, related technical field
Technical staff can also make various transformation or modification in the case where not departing from the spirit and scope of the utility model, because
This all equivalent technical solution also should belong to the scope of the utility model, should be limited by each claim.
