Abstract
The invention discloses a low-inductance square power cable for direct current distribution. The low-inductance square power cable comprises an inner core and a cable outer layer outside the cable inner core and is characterized in that the cable inner core comprises two parallel rectangular conductor wire cores, and a magnesium oxide insulating layer sleeves each rectangular conductor wire core; the cable outer layer sequentially comprises a braided shielding layer and an inorganic mineral fiber yarn layer from inside to outside; the section of the integral structure formed by the cable inner core and the cable outer layer is square. The low-inductance square power cable has the advantages that the cable is applicable to special ports used during client wiring; the cable is high in flame retardance during fire, the cable is free of halogen and low in fuming rate, and the cable does not generate toxic gases harmful to human bodies.
Description
Technical field
The present invention relates to field of cables, relate in particular to a kind of direct current and divide the low inductance of adapted square power cable.
Background technology
Conductor thread core and the insulating barrier of existing transferring electric power cable are generally circular configuration.But, for the square interface that part is special, need to select specific square power cable.
Summary of the invention
The object of the invention is to provide a kind of direct current to divide the low inductance of adapted square power cable, there is the characteristics such as low cigarette, Halogen, high temperature resistant, fire-retardant and low inductance.
To achieve these goals, technical scheme of the present invention is as follows:
A kind of direct current divides the low inductance of adapted square power cable, comprise cable inner core and wrap in the cable outer layer outside cable inner core, it is characterized in that: described cable inner core comprises two rectangle conductor thread cores be arranged in parallel, and two rectangle conductor thread cores are arranged with magnesium oxide insulated layer outward respectively; Described cable outer layer is followed successively by woven shield and inorganic mineral fiber layer from inside to outside, and the integrally-built section shape of cable inner core and cable outer layer composition is square.
In one embodiment of the invention, the surface of described rectangle conductor thread core is provided with anti-oxidation coating.
Profile of the present invention is square, has low inductive function, is applicable to the particular port that client's wiring uses.
The present invention, when breaking out of fire, has high flame retardant, not halogen-containing, and rate of being fuming is low, can not produce harmful toxic gas.
Long-term work of the present invention, and can bearing great current at the higher environment of temperature, can ensure the fail safe of system cloud gray model.
The detailed description and obtaining that feature of the present invention can consult the graphic and following better execution mode of this case is well understood to.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present invention.
Embodiment
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, setting forth the present invention further below in conjunction with specific embodiment.
As shown in Figure 1, a kind of direct current divides the low inductance of adapted square power cable, comprise cable inner core and wrap in the cable outer layer outside cable inner core, cable inner core comprises two rectangle conductor thread cores 10 be arranged in parallel, and the surface of rectangle conductor thread core is provided with anti-oxidation coating.Two rectangle conductor thread cores are arranged with magnesium oxide insulated layer 20 outward respectively; Magnesium oxide insulated layer is nearly 1400 DEG C of fusing point, Long-term service temperature 1200-1300 DEG C, puncture voltage reaches 230V/mm, specific insulation>=10
14the synthetic mineral insulation fire proofing material of Ω ˙ cm, continuous radial direction about 45
0angle is coated, requires to keep stable tension force and uniform tension force to form.
Cable outer layer is followed successively by woven shield 30 and inorganic mineral fiber layer 40 from inside to outside, and the integrally-built section shape of cable inner core and cable outer layer composition is square.Inorganic mineral fiber layer is with high temperature resistant 1400 DEG C of inorganic mineral fiber yarn class materials, radial intertexture (requiring coverage rate >=98%), and at its appearance dip-coating one deck organic synthesis solution, through 500-600 DEG C of hot conditionss are cured and are formed.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; the just principle of the present invention described in above-described embodiment and specification; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these changes and improvements all fall in claimed scope of the present invention.The protection range of application claims is defined by appending claims and equivalent thereof.
