This cable includes an at least cable core, the low smoke and zero halogen inner liner, armor and low smoke zero halogen sheath layer, this cable core by the conductor and in proper order flame retardant coating and the insulating layer of parcel outside the conductor constitute, regional packing the in space between all cable cores has fire -retardant gasket for packing, all cable cores wrap up outward in proper order has the low smoke and zero halogen inner liner, armor and low smoke zero halogen sheath layer, this low -smoke halogen -free flame -retardant fireproof cable is still including all cable cores of parcel, be in the fire -retardant glass area of the inboard of low smoke and zero halogen inner liner, and this armor is metal lock armo layer. Preferably, the utility model provides a low -smoke halogen -free flame -retardant fireproof cable is provided with the paper tape around the covering between metal armor layer and the low smoke and zero halogen inner liner.
Description
Technical field
The utility model relates to field of cable technology, more specifically must say, relates to a kind of low-smoke zero-halogen fire-resistant armoured power cable.
Background technology
At present, along with the frequent generation of electrical fire accident, the fire-retardant problem of electric wire causes everybody attention gradually.Traditional flame retardant cable mainly adopts flame-proof polyvinyl chloride, neoprene, the halogen containing material such as chlorosulfonated polyethylene reach as the sheath of cable the object suppressing propagation of flame, when fire occurs, above-claimed cpd easily decomposes effusion after being heated has severe toxicity in a large number, be corrosive HCL (hydrogen chloride) gas, and produce a large amount of hypertoxic dense smoke, cause great Loss of Life and property, and bring very large difficulty (as Korea S's subway big fire) to rescue work, particularly at the environment of space relative closure, during as used in the environment such as raceway groove or tunnel, hidden danger can be brought to Environmental security.Existing low-smoke zero-halogen fire-resistant cable many employings cross-linking polyethylene materials is as flame retardant coating, and its refractory temperature grade is up to 750 DEG C.Therefore need to provide a kind of both can when having burnt, do not discharge Halogen gas, smokescope is low, gas attack is low, its flame-retardant performance can be strengthened again, improve its refractory temperature, thus at utmost prevent the low-smoke halogen-free inflaming-retarding cable that fire occurs.
Utility model content
In order to improve the refractory temperature of cable, strengthen its flame-retardant performance, even and if do not discharge Halogen gas when burning yet, the utility model provides a kind of 950 DEG C of low smoke halogen-free fire retardant fire resistant cables.This cable comprises at least one cable core, low smoke and zero halogen inner covering, armour and low smoke and zero halogen restrictive coating, this cable core is made up of conductor and the flame retardant coating be wrapped in successively outside conductor and insulating barrier, void area between all cable cores is filled with flame resistant filler rope, all cable cores are enclosed with low smoke and zero halogen inner covering, armour and low smoke and zero halogen restrictive coating outward successively, the fireproof glass band of inner side that this low smoke halogen-free fire retardant fire resistant cable also comprises all cable cores of parcel, that be in low smoke and zero halogen inner covering, and this armour is metal lock armo layer.
Preferably, low smoke halogen-free fire retardant fire resistant cable provided by the utility model, is provided with paper tape lapping layer between metal armor layers and low smoke and zero halogen inner covering.
Low smoke halogen-free fire retardant fire resistant cable provided by the utility model, flame resistant filler rope can select glass-fiber reinforced electrodeless paper string or the netted tearing film gasket for packing of polypropylene flame redardant.
Low smoke halogen-free fire retardant fire resistant cable provided by the utility model, the material of its low smoke and zero halogen inner covering and low smoke and zero halogen restrictive coating can select low-smoke halogen-free polyolefin.
Low smoke halogen-free fire retardant fire resistant cable provided by the utility model, the flame retardant coating forming its cable core can select mica material.
Low smoke halogen-free fire retardant fire resistant cable provided by the utility model, the insulating barrier forming its cable core can select cross-linking polyethylene materials.
Low smoke halogen-free fire retardant fire resistant cable provided by the utility model, its conductor can be aluminium alloy conductor, and metal lock armo layer can be aluminium alloy lock armo layer.
Low smoke halogen-free fire retardant fire resistant armature of cable layer provided by the utility model adopts lock armo, when fire spreading in the external world is to armature of cable layer, the domes opposite planar structure of armour more can play cushioning effect to the rising of temperature, and the fireproof glass band being in lock armo inside has very high refractory temperature, even if low smoke and zero halogen inner covering and low smoke and zero halogen outer jacket all select halogen and also can not produce the polyolefine material of a large amount of smog when burning, cable provided by the utility model can obtain excellent high temperature low-smoke non-halogen flame-retardant performance; Due to flame resistant filler rope, the air content that glass-fiber reinforced electrodeless paper string as having good flame retardant effect is filled with the void area between cable core and reduces in cable, and the flame retardant coating be provided with between the insulating barrier of every root cable core and conductor as mica and so on, cable provided by the utility model can obtain obvious fire resistant flame retardant performance; The setting of paper tape lapping layer, can increase metal armor layers and be placed in the frictional force between the layer structure inside it, prevent slip between layers; And the wrapped construction of cable that more can make of paper tape is more tight closely, reduces the air content in Integral cable structure, more ensures the fire-resistance property of armoured cable.Experiment proves, by above technical scheme, the refractory temperature of low smoke halogen-free fire retardant fire resistant cable provided by the utility model can reach 950 DEG C, and flame retardant effect is obvious, can not produce a large amount of Halogen smog.
Accompanying drawing explanation
Fig. 1 is the structural representation of the preferred embodiment of low smoke halogen-free fire retardant fire resistant cable provided by the utility model.
Embodiment
As shown in Figure 1, a kind of every root cable core of low smoke halogen-free fire retardant fire resistant cable 1 is made up of stranded conductor 2 and the flame retardant coating 3 be wrapped in successively outside stranded conductor 2 and insulating barrier 4, flame resistant filler rope 5 is filled in the white space between cable core, is surrounded with fireproof glass band 6, low smoke and zero halogen inner covering 7, paper tape lapping layer 8, lock armo layer 9 and low smoke and zero halogen outer jacket 10 successively outside all cable cores and flame resistant filler rope 5.The conductor 2 of this cable 1 can be copper or aluminium alloy conductor, flame retardant coating 3 is mica, insulating barrier 4 is crosslinked polyethylene, flame resistant filler rope 5 is glass-fiber reinforced inorganic paper string, low smoke and zero halogen inner covering 7 and low smoke and zero halogen outer jacket 10 are low-smoke halogen-free polyolefin, and lock armo layer 9 can be aluminium strip lock armo, copper belt interlocking armored or steel band lock armo.More preferably, the conductor 2 of this cable can select aluminium alloy conductor, and lock armo layer 9 can use aluminium alloy lock armo structure.
This low smoke halogen-free fire retardant fire resistant cable 1 has significant flame-retardant performance, even if also can not discharge a large amount of gas containing halogen when burning.Experiment proves, the refractory temperature of this cable can reach 950 DEG C.
Above better embodiment of the present utility model is illustrated, but the utility model is not limited thereto, the various variants obtained in the scope not departing from its aim, all belongs to the scope that the present invention protects.
