Abstract
The utility model belongs to the field of below-35kv cables and particularly relates to a 35kv and below-35kv cold-resistant and high-temperature-resistant power cable. The 35kv and below-35kv cold-resistant and high-temperature-resistant power cable comprises a plurality of cable cores which consist of a plurality of cores. Each core consists of a conductor and an insulating layer. A twisted lapping tape is arranged outside the cable core. High-temperature-resistant fillers are filled between the twisted lapping tape and the cores. A reticular shielding layer which is woven by using copper wires is arranged outside the twisted lapping tape. A polyester lapping tape layer is arranged outside the reticular shielding layer. An elastic main insulating layer is arranged outside the polyester lapping tape layer. A cold-resistant sheath layer is arranged outside the main insulating layer. The 35kv and below-35kv cold-resistant and high-temperature-resistant power cable has the advantages that the cable can be used under different extremely cold or high temperature conditions, the service life is long and the reliability is high.
Description
Technical field
The utility model belongs to the following field of cables of 35kv, specifically is a kind of 35kv and following winter protection heatproof power cable.
Background technology
The applicability of power cable and fail safe can both normally transmit electric energy for using at special occasions; Some is not the accurately transmission signals of power cable, severe cold frost region very importantly, and harsh climate changes; Often do not reach instructions for use because of the cable cold tolerance; Break and open circuit, and cause electric power and transmission signals disorderly, make equipment produce misoperation, badly damaged with property causes casualties.
The cable core of the insulated wire cores stranding that existing heatproof cable mainly is made up of conductor and conductor surface insulation layer, on the cable core wrapped polyester band lapping layer with extrude oversheath and constitute.All being insulating material with the polytetrafluoroethylene, is sheath material with polyvinyl chloride or polyolefin, whole cable do not have any shielding construction or shielding properties bad.Therefore existing cable interference free performance is poor.Common cable is used in electrical control, and heat resistance and interference free performance can not play guaranteeing role to signal transmission and electric equipment safety simultaneously.Along with the development of society, the high temperature occasion is to the improve of electric automatic control required precision in producing and using.It is more and more important that the heat resistance of cable and interference free performance seem thereupon, uses common cable in producing and using, in case high temperature occurs or the interference meeting of high intensity magnetic field constitutes a threat to personal safety, causes the very big loss of production.
Summary of the invention
The problem that the utility model will solve provides the power cable of a kind of winter protection, heatproof, and it can adapt to open-air abominable natural environment, long service life.
The utility model provides following technical scheme:
35kv and following winter protection heatproof power cable, it comprises the cable core that some cores are formed, core is made up of conductor and insulating barrier; Cable core is outside equipped with the pair twist twining package tape; Be filled with the heatproof filler between pair twist twining package tape and the core, the pair twist twining package tape is provided with the mesh shields layer of copper wire braiding outward, and the mesh shields layer is provided with the wrapped belt of polyester outward; The wrapped belt peripheral hardware of polyester has the total insulating barrier of rubber-like, and total insulating barrier is provided with the Cold-proof covering layer outward.
Described conductor is single copper free wire.
The cross section of described copper free wire is a hexagon.
The utility model has the advantages that and can under the different condition of extremely cold or high temperature, use, long service life, reliability is high.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Embodiment
As shown in Figure 1,35kv and following winter protection heatproof power cable, it comprises the cable core that some cores are formed; In this execution mode three cores; Core is made up of conductor 1 and insulating barrier 2, and cable core is outside equipped with pair twist twining package tape 4, is filled with heatproof filler 3 between pair twist twining package tape and the core; The pair twist twining package tape 4 outer mesh shields layers 5 that are provided with the copper wire braiding; The mesh shields layer 5 outer wrapped belt 6 of polyester that is provided with, the wrapped belt 6 outer total insulating barriers 7 of rubber-like that are provided with of polyester, total insulating barrier 7 outer Cold-proof covering layers 8 that are provided with.
Described conductor is single copper free wire.
The cross section of described copper free wire is a hexagon.
