The utility model discloses because the insulating layer all adopts fluorine rubber materials with the outer jacket, has high fire behaviour, make variable frequency cable can be used for the high temperature occasion, through the foaming layer, strengthened variable frequency cable's resistance to compression tensile ability, prolonged life, adopting the shielding layer as the aluminium foil layer, can strengthening power supply system's equilibrium, messenger variable frequency cable has stronger resistant surge nature, has still strengthened the shielding effect, because aluminum alloy armor sheath intensity is high, peel off easily and the compliance good, be difficult for causing the damage in transportation, installation and use.
Description
Technical field
This utility model belongs to field of cable technology, especially relates to a kind of frequency-changing cable.
Background technology
Frequency-changing cable is generally used for the power transmission line of frequency conversion system, is widely used in work, agricultural, army
In the every profession and trade such as thing, scientific research, especially at papermaking, metallurgy, intermetallic composite coating, mine, railway and food
In the industries such as processing, it is more widely applied.
The fire resistance of traditional frequency conversion cable is poor, the most aging until cable report in high-temperature field credit union especially
Useless, it is impossible to such as melt the occasions such as iron furnace for high temperature applications；But the screen layer of existing frequency-changing cable is mainly used
The combination shielding of copper wire copper strips, proof copper-wire braided shielding, copper strip shielding and proof copper-wire braided copper strip shielding etc., use
This shielding layer structure, although have certain resistance to surge and shield effectiveness, but cost is the highest, so that
Itself is the heaviest, and the problem of higher hamonic wave easily occurs, makes supply voltage distort, and quality of voltage declines,
Line loss increases；And current frequency-changing cable bulk strength is more weak, under a few thing environment, often meets
To crimping, pull, move and hanging the situations such as wiring, it is in stress for a long time, reduces use
Life-span；And during transportation, installation and use, frequency-changing cable easily causes damage, is therefore changed
Enter.
Summary of the invention
The purpose of this utility model is the deficiency existed for above-mentioned prior art, it is provided that a kind of frequency-changing cable,
The high flame resistance that it has, the higher hamonic wave that can reduce in circuit, minimizing line loss, resistance to compression tension
Intensity easily causes greatly and not the feature of damage.
In order to realize above-mentioned purpose, this utility model be the technical scheme is that a kind of frequency-changing cable,
Including core；Described core includes master core and zero line core, described master core and zero line core include conductor and
Insulating barrier, described insulating barrier is wrapped in outside conductor, has additional foaming layer between described conductor and insulating barrier；
Described insulating barrier is fluorubber insulating barrier；Be provided with from inside to outside outside described core gasket for packing, lapping layer,
Screen layer, aluminium alloy armored sheath and outer jacket；Described screen layer is aluminium foil layer；Described outer jacket is fluorine
Rubber sheath.
Described master core and zero line core all around the center of circle of frequency-changing cable each other in 120 degree of distributions.
Described fluorubber insulating barrier uses oxygen index (OI) to reach the fluorubber plastics of 75.
Described gasket for packing is flame resistant filler rope.
The outer wall of described outer jacket is provided with corrosion-resistant coating.
After using said structure, compared to the prior art this utility model has the advantage, that this practicality is new
Type simple in construction, owing to insulating barrier and outer jacket all use fluorubber material, has high flame resistance, makes
Frequency-changing cable can be used in high temperature applications, can safely and steadily run in the environment such as hot blast, high-temperature particle；
By the setting of foaming layer, enhance the resistance to compression resistance to tension of frequency-changing cable, extend service life；Adopt
With screen layer as aluminium foil layer, it is possible not only to strengthen the balance of electric power system, makes frequency-changing cable have relatively
Strong resistance to surge, but also enhance shield effectiveness；Owing to aluminium alloy armored sheath intensity is high, stripping
From easy and flexibility good, during transportation, installation and use, do not easily cause damage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
The following stated is only preferred embodiment of the present utility model, the most therefore limits of the present utility model
Protection domain, further illustrates this utility model with embodiment below in conjunction with the accompanying drawings.
Embodiment, as shown in Figure 1, a kind of frequency-changing cable, including core, core include master core 10 and
Zero line core 11, master core 10 and zero line core 11 all around the center of circle of frequency-changing cable each other in 120 degree
Distribution, improves stability.Master core 10 and zero line core 11 include conductor 12 and insulating barrier 13, insulation
Layer 13 is wrapped in outside conductor 12, has additional foaming layer 14 between conductor 12 and insulating barrier 13, by sending out
The setting of alveolar layer 14, improves the protectiveness of frequency-changing cable, enhances the resistance to compression resistance to tension of frequency-changing cable,
Extend service life.Insulating barrier 13 is fluorubber insulating barrier, and fluorubber insulating barrier uses oxygen index (OI) to reach 75
Fluorubber plastics, there is high flame resistance, breakdown strength is high, can be steady in a long-term under 200 DEG C of high temperature
Run, and the oxygen index (OI) very effective prevention fire spreading of energy of up to 75, reach fire-retardant effect.Line
Gasket for packing 15, lapping layer 16, screen layer 17, aluminium alloy armored sheath 18 it is provided with from inside to outside outside core
And outer jacket 19；Gasket for packing 15 is flame resistant filler rope, further up to fire-retardant effect.Screen layer 17
For aluminium foil layer, use screen layer 17 as aluminium foil layer, be possible not only to strengthen the balance of electric power system, make
Frequency-changing cable has stronger resistance to surge, but also enhances shield effectiveness.Due to aluminium alloy armored
