Abstract
The utility model discloses a strenghthened type three -sphase four -wire system power cable, it includes three cable conductor unit and a cable grounding unit, and during three cable conductor unit and a cable grounding unit were in the insulating layer, the insulating layer outer wall was equipped with the inoxidizing coating, and the outer wall of inoxidizing coating is equipped with the restrictive coating, it has shielding material to fill in the space between insulating layer and three cable conductor unit, the cable grounding unit. It is done all can under the unchangeable condition in the power supply, can reduce the sectional area of cable to reduce the volume of cable, reduce cost greatly.
Description
Technical field:
This utility model relates to field of cable technology, a kind of reinforced three-phase four-wire system power cable.
Background technology:
Existing power cable typically uses three cable conductor unit and a cable grounding unit composition, it is usually and is provided with a cable grounding unit middle, then three cable conductor unit are uniform centered by cable grounding unit forms, owing to needs are rounded by power cable section, so adopt the structure, space between three cable conductor unit and a cable grounding unit is increased, more shielding material implant is needed to fill space, increase cost of manufacture, and the volume of power cable is increased, the cross-section of cable is long-pending to be increased, affect it install and use.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of reinforced three-phase four-wire system power cable, and it, in the case of constant for electric power, can reduce the sectional area of cable, thus be substantially reduced the volume of cable, reduces cost.
This utility model solves the scheme of described technical problem:
A kind of reinforced three-phase four-wire system power cable, it includes three cable conductor unit and a cable grounding unit, three cable conductor unit and a cable grounding unit are in insulating barrier, and insulating barrier outer wall is provided with overcoat, and the outer wall of overcoat is provided with restrictive coating；
Space between described insulating barrier and three cable conductor unit, cable grounding unit is filled with shielding material.
The cross section of described three cable conductor unit is fan shape, the cylinder of three cable conductor unit compositions 3/4ths, and cable grounding unit is cylinder, three cable conductor unit and a cable grounding unit and shielding material composition cylinder.
Described three cable conductor unit and a cable grounding cellular construction are, and are provided with the copper stranded conductor stranded by many copper cash in exterior insulation body.
Described overcoat is steel bushing layer.
Described three cable conductor unit are the first live wire, the second live wire and the 3rd live wire, and cable grounding unit is zero line.
The outer wall of described restrictive coating is evenly equipped with multiple lobe, is fixed with reinforcement steel wire in lobe.
Prominent effect of the present utility model is:
Compared with prior art, it, in the case of constant for electric power, can reduce the sectional area of cable, thus be substantially reduced the volume of cable, reduces cost.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention:
The utility model is elaborated with concrete preferred embodiment below in conjunction with the accompanying drawings, so that advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, these embodiments are only the purpose illustrated, it is no intended to be defined scope of the present utility model.
Embodiment, see as shown in Figure 1, a kind of reinforced three-phase four-wire system power cable, it includes three cable conductor unit 1 and a cable grounding unit 2, three cable conductor unit 1 and a cable grounding unit 2 are in insulating barrier 3, insulating barrier 3 outer wall is provided with overcoat 4, and the outer wall of overcoat 4 is provided with restrictive coating 5；
Space between described insulating barrier 3 and 1, cable grounding unit 2 of three cable conductor unit is filled with shielding material 6.
Further, the cross section of described three cable conductor unit 1 is fan shape, three cable conductor unit 1 form the cylinder of 3/4ths, and cable grounding unit 2 is cylinder, and three cable conductor unit 1 and a cable grounding unit 2 and shielding material 6 form cylinder.
Further, described three cable conductor unit 1 and cable grounding unit 2 structure are, and are provided with the copper stranded conductor 12 stranded by many copper cash in exterior insulation body 11.
Further, described overcoat 4 is steel bushing layer.
Further, described three cable conductor unit 1 are the first live wire, the second live wire and the 3rd live wire, and cable grounding unit 2 is zero line.
Further, the outer wall of described restrictive coating 5 is evenly equipped with multiple lobe 51, is fixed with reinforcement steel wire 52 in lobe 51.
In the present embodiment, by the cross-sectional layers fan shape of three cable conductor unit 1, three cable conductor unit 1 form the cylinder of 3/4ths, cable grounding unit 2 is cylinder, three cable conductor unit 1 and a cable grounding unit 2 and shielding material 6 form cylinder, it makes in unit cross-sectional area, the area area occupied of three cable conductor unit 1 is big, improve the effect of power transmission, that is, in the case of constant for electric power, the sectional area of cable can be reduced, thus it is substantially reduced the volume of cable, reduce cost.
Meanwhile, its overcoat 4 added is steel bushing layer so that when outer sheath layer 5 damages, three the cable conductor unit 1 within cable and a cable grounding unit 2 can be protected the most impaired, improves service life.
And the outer wall of restrictive coating 5 is evenly equipped with multiple lobe 51, being fixed with reinforcement steel wire 52 in lobe 51, it strengthens the intensity of this cable further, improves service life.
Embodiment of above is merely to illustrate this utility model; and be not limitation of the utility model; those of ordinary skill about technical field; in the case of without departing from spirit and scope of the present utility model; can also make a variety of changes and modification; the technical scheme of the most all equivalents falls within category of the present utility model, and scope of patent protection of the present utility model should be defined by the claims.
