Abstract
A kind of optical fiber power cable, comprise six roots of sensation conductive cores, be arranged on outside every root conductive cores is insulating barrier, be arranged on outside six roots of sensation conductive cores insulating barrier is coated copper strip shielding layer, be arranged on outside copper strip shielding layer is the second insulating barrier and outer jacket, the centre of six roots of sensation conductive cores is a plastic fiber, and plastic fiber skin is elastomer integument, and elastomer integument diameter is identical with the diameter of the conductive cores of every root tape insulation layer.Above-mentioned enterprise optical fiber power cable, can the power of nearly hundred KW of electric power transfer, data is transmitted with the light velocity simultaneously, do not affect the function of cable, do not affect the transfer function of optical fiber, and can strengthen the intensity of cable by plastic fiber.
Description
Technical field
The utility model relates to a kind of power cable, particularly relates to a kind of band optical fiber power cable.
Background technology
The electric pressure of common multi-core power cable is generally 35kV, the structure of existing 35kV Six-core power cable comprises: outer jacket and six cable cores be evenly arranged in outer jacket, inserts is provided with between six cable cores in outer jacket, the structure of described cable core comprises: conductor, be arranged on the conductor shield outside conductor, be arranged on the insulating barrier outside conductor shield, be arranged on the shielding layer of copper wires outside insulating barrier, be arranged on the copper strip shielding layer outside shielding layer of copper wires.Above-mentioned 35kV tri-core power cable transmission capacity is less, and transmission range is comparatively near, and the self transmission loss of power cable is comparatively large, and the quality percentage of cable is not high.
The applicant proposes a kind of single core and three core power cables at CN202003753 and CN202003754, makes the quality percentage of cable up to three core power cables of 45kV level.Described power cable, comprising: outer jacket and one or three cable cores being evenly arranged in outer jacket; Inserts is provided with between three cable cores in outer jacket, the structure of described cable core comprises: conductor, be arranged on the conductor shield outside conductor, be arranged on the insulating barrier outside conductor shield, be arranged on the shielding layer of copper wires outside insulating barrier, be arranged on the copper strip shielding layer outside shielding layer of copper wires, also insulation screen is provided with in the outside of described insulating barrier, insulation screen is made up of some spaced insulation shielding bars be evenly arranged on outside insulating barrier, and the copper wire of shielding layer of copper wires is dredged equably around on insulation shielding bar; Also equadag coating is provided with outside described outer jacket.
Prevent cable to be in operation the infringement of induced electromotive force to cable with equadag coating, can protect cable well, equadag coating is mixed by graphite and functional agent, and functional agent can be adhesive, colouring agent or pest repellant, improves the comprehensive function of cable.Existing equadag coating and outer jacket without positive impact, and have employed shielding layer of copper wires and the two-layer screen of copper strip shielding layer compares redundancy and waste to the life-span of cable.
Utility model content
The purpose of this utility model is, provides enterprise's optical fiber power cable that a kind of certain area distributes, does not affect the function of cable, do not affect the transfer function of optical fiber, and can strengthen the intensity of cable.
A kind of optical fiber power cable, it is characterized in that comprising six roots of sensation conductive cores, be arranged on outside every root conductive cores is insulating barrier, be arranged on outside six roots of sensation conductive cores insulating barrier is coated copper strip shielding layer, be arranged on outside copper strip shielding layer is the second insulating barrier and outer jacket, the centre of six roots of sensation conductive cores is a plastic fiber, and plastic fiber skin is elastomer integument, and elastomer integument diameter is identical with the diameter of the conductive cores of every root tape insulation layer.
The beneficial effects of the utility model: above-mentioned enterprise optical fiber power cable, can the power of nearly hundred KW of electric power transfer, by plastic fiber, data are transmitted with the light velocity simultaneously, do not affect the function of cable, do not affect the transfer function of optical fiber, and the intensity of cable can be strengthened, can transmit distribute control information and the picture control information of 1-2Km, the production process image in particular for certain power apparatus is monitored.Protecting to some extent plastic fiber, is also have buffering drawing-resistant function to the cable of six conductive cores.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model 45kV single-core power cables.
In figure: conductive cores 1, insulating barrier 2, copper strip shielding layer 3, inserts 4, second insulating barrier 5, outer jacket 6, plastic fiber 7, elastomer layer 8.
Embodiment
Particular content of the present utility model is described in detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, power cable, comprise: six roots of sensation conductive cores 1, be arranged on outside every root conductive cores 1 is insulating barrier 2, be arranged on outside six roots of sensation conductive cores insulating barrier is copper strip shielding layer and the outer jacket 6 be arranged on outside copper strip shielding layer 3, the centre of six roots of sensation conductive cores 1 is a plastic fiber, and plastic fiber skin is elastomer layer parcel, and the plastic fiber diameter of elastomer layer parcel is identical with the diameter of the conductive cores 1 of every root tape insulation layer 2.
With regard to Fig. 1 cross section; six roots of sensation conductive cores and insulating barrier 2 form hexagon; the plastic fiber of elastomer layer parcel is placed in center; plastic light delicate fingers has the plastic fiber of outer jacket; elastomer layer 8 is PE elastomer; having good intensity, not only protect to some extent plastic fiber, is also the effect cable of six conductive cores being had to buffering and tension.Electromagnetic interference can not affect transmission characteristic; Electrical isolation---without the need to potential balance, lightweight, there is minimum size simultaneously.The insulating inorganic dusty material of inserts 4 is filled between six roots of sensation conductive cores and optical fiber elastomer layer; Second insulating barrier 5 is the insulating material such as PE or PVC.
In the present embodiment, the vulcanized rubber that described insulating barrier is identical with outer jacket, the thickness of outer jacket is 1.5-3mm, see CN 101580606.During preparation, coupling agent treatment is carried out on surface, for the preparation of outside outer jacket after sulfuration.
Above-described embodiment is not to restriction of the present utility model; those of ordinary skill in the art; when not departing from the utility model spirit and protection range, can also make various change and modification, therefore all equivalent technical schemes do not exceed protection range of the present utility model yet.
