Brief description of the drawings
Fig. 1 is the structural representation of the single core of the utility model；
Fig. 2 is three structural representations of core of the utility model.
Specific embodiment
Flexible cable, including at least single line core and fireproof covering are pressed in a kind of low smoke halogen-free fire retardant fire resistant as shown in Figure 1, 2,
The core includes conductor 1, semi-conductive shield 2, insulating barrier 3, insulation screen 4, metal screen layer 5 successively from inside to outside.
Core can be set to one or more, and multilayer screen, insulating barrier are set outside core, can effectively reduce the security incident of electric leakage,
Reduce electric jamming.Wherein, semi-conductive shield 2 uses MP metallized paper or semiconducting paper, can so make insulating barrier 3 and conductor
1 has preferably contact, eliminates the increase of the rough surface field intensity of conductor 1 for causing of conductor 1.
In order to reach the effect of shielding electric field, metal screen layer 5, the metal are provided with the outside of insulation screen 4
Screen layer 5 is formed by copper wire is wrapped, and the periphery of the metal screen layer 5 is provided with epoxy anticorrosive coating.Corrosion-resistant epoxy paint
Wearability is good, and adhesive force is strong, also with good water resistance, can not only well protect cable core, and enhance cable
Water-proof function, cable also can be normally used in humid area.
When the core in cable is set to three, it is additionally provided between the metal screen layer 5 and fireproof covering of core
Packed layer 10, the packed layer 10 can make that the structure of cable is even closer, leave no gaps, and fireproof covering is closely wrapped up online
Core outside, strengthens the security reliability of cable.The filler of the packed layer 10 can be fire resistance fibre, and fire resistance fibre is in itself not
Flame can occur, and fire resistance fibre once leaves self-extinguish by naked light burning things which may cause a fire disaster, is to protect cable core to be destroyed from fire
Last line of defense.Or the filler of the packed layer 10 is EVA resin, EVA resin has good filler pardon
And cross linkable, its vinyl acetate content is controlled 12%~24%.
In order to reach more preferable flameproof effect, the fireproof covering includes refractory insulating layer 6, water-absorbing resin successively from inside to outside
Layer 7, flame retardant bed 8 and sheath 9.Described refractory insulating layer 6 is made up of fire-resistant isinglass belt and alkali-free glass fibre double-decker, institute
State alkali-free glass fibre and be wrapped in fire-resistant isinglass belt outside.Fire-resistant isinglass belt has excellent resistance to elevated temperatures and flame resistance
Can, the volatilization of harmful vapors is substantially not present when naked light burning is run into, the security of cable can be strengthened.And it is wrapped in fire resisting
Alkali-free glass fibre on the outside of mica tape has a pulling force extra-heavy, resistance to vulcanization, and pure oxygen is non-ignitable and smokeless halogen-free is nontoxic, insulating properties
It is good, heat-insulated, oxygen barrier effect can be played, improve the flame retardant rating of cable.The flame retardant bed 8 uses Ceramic silicon rubber, should
Material can cause ceramic when fire occurs because of high temperature, form ceramic-like housing, protect cable core not broken by flame combustion
It is bad, cable is adhered to after naked light is run into using a period of time more, it is that the rescue in fire is raced against time.
The resin 7 that absorbs between refractory insulating layer 6 and flame retardant bed 8 has high absorbent function, and water retention property is excellent
It is good, can in absorptance itself hundreds of Dao thousands of times water, can not only absorb the moisture of infiltration, prevent cable in wet environment
In be etched, refractory insulating layer can also be aided in carry out fire prevention and heat-insulated, strengthen security reliability of the present utility model.
First protective layer that the outermost sheath 9 of fireproof covering is cable is arranged on, can be using Halogen materials such as polyethylene
Material, or low smoke and zero halogen oxygen barrier material is used, when by flame calcination, itself does not prolong combustion to such cable, and smoke amount is very low,
Toxic gas will not be produced, it is to avoid the secondary injury of fire.
