Description
Technical field
The present invention relates to field of cable technology, more particularly to a kind of fire prevention armored cable.
Background technology
With increase of all trades and professions to electricity needs, the use of cable and the requirement of cable laying and environment also by
In gradually improving.The cable of common single type can not meet present various demands.In existing cable laying with using
During, the defects such as low construction efficiency, production cost are high, security performance is low be present.
Existing metal armouring generally has following several forms：Clad steel band laminated armor, wire armoring and wire
Net armouring, the bending property of cable is limited, resisted external force and mechanical protection scarce capacity.
The content of the invention
Prevent fires armored cable the invention provides one kind, have by the first armor and the second armor cable
Good bending, twisting property, it can adapt to foreign impacts destruction.
In order to reach the purpose, the present invention adopts the following technical scheme that：Including the insulation coated on cable core, the cable core
Layer, the insulating barrier outside are provided with screen layer, packed layer are provided between the insulating barrier and the screen layer, it is characterised in that：
The first armor, the second armor and fire-retardant oversheath, first armour are closely extruded with from inside to outside on the outside of the screen layer
Dress layer and second armor include the wire being uniformly arranged, and bearing of trend of the wire along the cable core is around described
The hand of spiral of cable core screw winding, first armor and the wire in second armor is on the contrary, described
Polyethylene and graphene conductive powder are filled with first armor, flame retardant of magnesium hydroxide is filled with second armor.
Thus, the first armor of reverse acting spiral spread configuration and the second armor ensure that cable torsional strength and
Outer drawing and interior tensile strength, the first armor is interior to be balanced efficiently to electricity filled with polyethylene and graphene conductive powder and wire
Cable is radiated, and improves the anti-flammability of cable in the second armor filled with flame retardant of magnesium hydroxide, reduces wire to armouring
The crimp of layer side wall.
As a preferred embodiment, the wire is high-carbon steel wire, a diameter of 0.3-0.5mm of the high-carbon steel wire is adjacent
Spacing distance between the high-carbon steel wire is less than the 1/4 of its diameter.The construction of cable is close, stable work in work.
As a preferred embodiment, the wire is flat steel wire, the arcuate side surface of the adjacent flat steel wire, which offsets, to be set
Put.
As a preferred embodiment, the helical angle of the wire is 20 ° -25 °.
As a preferred embodiment, first armor and the second armouring interlayer are provided with fireproof glass silk braiding layer.
As a preferred embodiment, the fire-retardant oversheath is by the semi-rigid polyvinyl chloride group containing preservative and antioxidant
Into.
Thus, cable can use in the presence of a harsh environment, be less prone to crackle.
To sum up, compared with prior art, the advantage of the invention is that：Anti-torsion performance greatly improves, and armor is along cable
Bearing of trend has certain elasticity, reduces its destruction probability under external load function；Polyethylene is filled with first armor
Efficiently cable is radiated with graphene conductive powder and wire balance, avoids heat aggregation from causing thermal breakdown of insulating；
The anti-flammability of cable is improved in second armor filled with flame retardant of magnesium hydroxide, reduces extruding of the wire to armor side wall
Deformation.
Brief description of the drawings
Fig. 1 is the cross section structure schematic diagram of the first embodiment of the invention；
Fig. 2 is the cross section structure schematic diagram of second of embodiment of the invention.
Label in figure is as follows：
1. cable core, 2. insulating barriers, 3. screen layers, 4. packed layers, 5. first armors, 6. second armors, 7. fire-retardant oversheaths,
8. braiding layer.
Embodiment
The invention will be further described for middle embodiment below in conjunction with the accompanying drawings.
As shown in figure 1, the cable includes cable core 1, the insulating barrier 2 coated on cable core 1.The outside of insulating barrier 2 is provided with screen layer
3, packed layer 4 is provided between insulating barrier 2 and screen layer 3.The outside of screen layer 3 is closely extruded with the first armor 5, the from inside to outside
Two armors 6 and fire-retardant oversheath 7, the first armor 5 and the second armor 6 include the wire being uniformly arranged, wire edge
The bearing of trend of cable core 1 is around the screw winding of cable core 1, the hand of spiral phase of the first armor 5 and the wire in the second armor 6
Instead.Polyethylene and graphene conductive powder are filled with first armor 5, flame retardant of magnesium hydroxide is filled with the second armor 6.
The first armor 5 and the second armor 6 of reverse acting spiral spread configuration ensure that the torsional strength of cable, in the first armor 5
Efficiently cable is radiated filled with polyethylene and graphene conductive powder and wire balance, filled out in the second armor 6
The anti-flammability of cable is improved filled with flame retardant of magnesium hydroxide, reduces crimp of the wire to armor side wall.
As shown in figure 1, wire is high-carbon steel wire, a diameter of 0.3-0.5mm of high-carbon steel wire, between adjacent high-carbon steel wire
Spacing distance is less than the 1/4 of its diameter.The construction of cable is close, stable work in work.
As shown in Fig. 2 wire elects flat steel wire as, the arcuate side surface of adjacent flat steel wire offsets setting.
