Description
Technical field
The present invention relates to power equipment technical field, especially a kind of high voltage power cable.
Background technology
Along with the continuous expansion of the industry sizes such as China electric power industry, data communication industry, urban track traffic industry, car industry and shipbuilding, also will increase rapidly the demand of electric wire, following electric wire industry also has huge development potentiality, the application of power cable is more and more wider, power cable is the cable for transmitting and distribute electric energy, and power cable is usually used in Urban Underground electrical network, power station lead line, industrial and mining enterprises' in-line power and power transmission line under crossing river seawater.In power circuit, cable proportion increases just gradually, and power cable is the cable product in order to transmission and distribution high-power power in the basic routing line of electric power system, comprises 1-500KV and above various electric pressure, but, there is many weak points in power cable in the market, the power cable volume of various insulation is large, and cost is high, bending difficulty, produce and lay difficulty comparatively large, therefore, we have proposed a kind of high voltage power cable for the problems referred to above.
Prior art can not meet the needs of people; for making up prior art deficiency; the present invention aims to provide a kind of high voltage power cable; good blocking-up protective effect is made it have by arranging conductor screen; insulating barrier prevents power loss; protection transmission of electricity environment; ensure that current-carrying quality; further waterstop and aluminium cover part prevent the effects such as the interference of external environment; there are good economic benefit and social benefit; being applicable to series of advantages such as promoting the use of, by optimizing overall design, solving the problem in background technology.
For achieving the above object, the present invention by the following technical solutions: a kind of high voltage power cable, comprises conductor, insulating barrier, waterstop, aluminum plastic belt, conductor shield, insulation screen, shielding layer of copper wires and sheath; Described conductor arranged outside conductor shield, and fill insulating barrier outside conductor shield; Described insulating barrier axle center arranges conductor, and insulating barrier arranged outside insulation screen; Described insulation screen and insulating barrier close adhesion, and insulation screen arranged outside waterstop; Described waterstop outer felt is around shielding layer of copper wires, and shielding layer of copper wires arranged outside aluminum plastic belt; Fixed sheath outside described aluminum plastic belt and sheath and the conductor coaxial heart.
Further, the braiding of described aluminum plastic belt closely parcel shielding layer of copper wires and shielding layer of copper wires spiral wrap outside waterstop.
Further, described conductor is closely wound up as entirety by copper cash and conductor is cylindrical structural.
Further, described insulating barrier, shielding layer of copper wires are all arranged with conductor axle center.
The invention has the beneficial effects as follows: prevent cable in the useful life of running and reducing because moisture immerses crosslinked polyetylene insulated formation water tree in laid processes cable, adopt metallic sheath transposition connected mode in design simultaneously, the loss of cable metal sheath layer is little, also relatively improve transmission capacity, on the other hand, because voltage is high, insulating layer thickness, conductor screen has good blocking-up protective effect, insulating barrier prevents power loss, protection transmission of electricity environment, ensure that current-carrying quality, further waterstop and aluminium cover part prevent the effects such as the interference of external environment, there are good economic benefit and social benefit, be applicable to promoting the use of.
