Abstract
The utility model relates to a beam-bearing aerial cable which comprises three cable core units, a bearing steel wire unit and a steel connecting line; the three cable core units are twisted into a cable; the bearing steel wire unit is parallel to the cable core unit and is arranged at the edge of a cable core; and the steel connecting line wraps up the bearing steel wire unit and the cable core unit together in a spiral way. The beam-bearing aerial cable is safe and reliable, and convenient for construction; and as current of a three-phase alternating current circuit is zero, inductance is not generated, circuit loss is low, energy-saving function can be realized, and the beam-bearing aerial cable is applicable to large-scale circuit remodeling of cities.
Description
Technical field
The utility model relates to a kind of cable, especially relates to a kind of bundle aerial cable that holds.
Background technology
Present aerial cable is that single core lays, and the distance between the single line is about 1.1 meters, though there is the standard of holding the bundle aerial cable not have structure.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model proposes hold the bundle aerial cable can not only carry big weight, also can concentrate and lay.
In order to realize the foregoing invention purpose, the utility model adopts following technical scheme:
A kind of bundle aerial cable that holds comprises three cable core unit, carrying steel wire unit, steel line; Three stranded strandings in cable core unit; Carrying steel wire unit parallels with the cable core unit, is placed on the cable core edge; The steel line will carry the steel wire unit and be in the same place with cable core unit coil wrapping.
The cable core unit comprises that conductor, conductor screen, XLPE insulation, insulation shielding, copper strips shielding, PVC sheath dispose from inside to outside.
Carrying steel wire unit comprises that steel strand wire, PVC sheath dispose from inside to outside.
Wherein 1 is carrying steel wire unit, the 2nd, and cable core unit, the 3rd, steel line.1-1 is steel strand wire, the 2nd, and the PVC sheath.2-1 is that conductor, 2-2 are that conductor screen, 2-3 are that XLPE insulation, 2-4 are that insulation shielding, 2-5 are that copper strips shielding, 2-6 are the PVC sheaths.
The beneficial effects of the utility model are to be applicable to that the city line corridor is smaller, the built on stilts occasion that power consumption is bigger, it improves more than the twice than normal single core aerial cable, safe and reliable, easy construction because the electric current of three-phase AC line is zero, does not produce inductance, line loss has power saving function for a short time, is applicable to the large-scale city track remodelling.

Embodiment
A kind of bundle aerial cable that holds comprises three cable core unit, carrying steel wire unit, steel line; Three stranded strandings in cable core unit; Carrying steel wire unit parallels with the cable core unit, is placed on the cable core edge; The steel line will carry the steel wire unit and be in the same place with cable core unit coil wrapping.
The cable core unit comprises that conductor, conductor screen, XLPE insulation, insulation shielding, copper strips shielding, PVC sheath dispose from inside to outside.
Carrying steel wire unit comprises that steel strand wire, PVC sheath dispose from inside to outside.
Wherein 1 is carrying steel wire unit, the 2nd, and cable core unit, the 3rd, steel line.1-1 is steel strand wire, the 2nd, and the PVC sheath.2-1 is that conductor, 2-2 are that conductor screen, 2-3 are that XLPE insulation, 2-4 are that insulation shielding, 2-5 are that copper strips shielding, 2-6 are the PVC sheaths.
With cross-linked cable insulating core color separation copper strips shielding-nonwoven fabrics wrapped-the PVC sheath after the stranded stranding of three-phase squeeze the weather-proof PE parallel placement of insulating with steel strand wire again, use 2mm
2Steel cord insulated wire becomes cable core to be held together in three cores by certain pitch, the steel cord plays a part to fix three cores and becomes cable core and steel strand wire, the steel strand wire load capacity, the transmission of power of the crosslinked core carrying of three cores circuit, the insulation thickness of crosslinked core will determine according to electric pressure, and the insulation thickness of 6//10kV, 8.7/10kV, 12/20kV, 21/35kV is respectively 3.4,4.5,5.5,9.3mm.
