Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
In figure：Main conductor core 1, insulating barrier 2, belting layer 3, sheath 4, ground wire 5, chain armor 6, outer jacket 7.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the utility model is described in further detail.
A kind of chain steel-tape armouring low-voltage variable frequency power cable, comprising main conductor core 1, insulating barrier 2, belting layer 3, interior
Sheath 4, ground wire 5, chain armor 6 and outer jacket 7, the main conductor core 1, ground wire 5 respectively have three, and insulating barrier 2 is extruded
The outside of main conductor core 1 is arranged on, ground wire 5 is uninsulated structure, is arranged between the side gap of main conductor core 1, main line
Conductor thread core 1, ground wire 5 are combined as into cable core, and belting layer 3, sheath 4, chain armor 6, outer jacket 7 are from the inside to the outside successively
It is coated on into the outside of cable core.
The main conductor core 1, the core of ground wire 5 are shaped as circle, and conductor is that height presses albronze conductor, conductor
Press coefficient not less than 90%.
The material of the insulating barrier 2 is weather-proof IXPE material, and the main body of insulating barrier 2 is black color structure,
Insulating, color separation part is crowded to be provided with vitta.
The material of the chain armor 6 is four sides galvanized steel strip.
The material of the outer jacket 7 is the low temperature resistant PVC sheath material of environmental-protection flame-retardant.
In actual applications, main conductor and gnd conductor are that height presses albronze conductor, conductor press coefficient >=
90%, conductor is effectively reduced conductor diameter in the case where meeting conductor resistance, reduce finished product manufacturing cost.
Ground wire core is uninsulated structure, is individually positioned in side gap between main line insulated wire cores.Gnd conductor is twisted and production is adopted
Realized with nanometer mould and press strand and make gnd conductor that there is the surface of smooth rounding, it is to avoid because of hair caused by compacting degree height
The generation of thorn, while also avoiding stabbing main line insulation is damaged because of burr causes core to puncture.
Main line core insulating barrier be weather-proof IXPE material, due to cable during wiring use insulated wire
Core has partial denudation in the sunlight, and the weather resistance of insulation ensures that exposed part insulated wire cores are used for a long time not open in the sunlight
Split, insulating properties do not change.Insulated wire cores insulating body color is black, and it is resistance to that black insulation can be such that insulated wire cores had both met
The performance of time has relatively low material production cost again.Insulation color separation is realized using vitta is extruded in black insulating surface.
Chain armor material uses four sides galvanized steel strip, and four sides galvanized steel strip is met：Immerse copper-bath 2 times, often
Secondary 60 seconds, steel strip surface was without any bright copper after testing every time.
Outer jacket is the low temperature resistant PVC sheath material of environment-friendly type environmental-protection flame-retardant, with excellent resistance to low temperature,
Also there is excellent fire resistance simultaneously, effectively prevent cable from being damaged from external mechanical, while also avoiding because of long-term work
And to the pollution of environment.
