Description
Technical field
This utility model relates to power cable field, and referring in particular to a kind of rated voltage is 8.7/10kV and following single high voltage power cable.
Background technology
Along with the development of society, city is increasing, and power load is more and more higher, and the safety requirements of power supply is more and more important.Urban electricity supply circuit is more and more closeer, become increasingly complex, and needs because of the city appearance of the city, it is desirable to the most attractive in appearance simultaneously, does not use overhead transmission line as far as possible, uses as much as possible and put cable underground.Based on above reason, present large-scale, megapolis use the high-voltage cross-linking polythene cable of 10kV in a large number, get off to complete the conveying of Large Copacity electric energy by ground, to meet the demand of densely populated metropolis power consumption.
High tension cable is the one of power cable, refers to the power cable for transmitting between 10KV-35KV, is applied to the major trunk roads of electric power transmission more.Some high tension cable needs to be embedded under earth's surface, is possible to prevent the damage of other external force, but thus needs to resist the compressing of high intensity on ground.
The structure composition of 10kV high voltage power cable mainly has conductor, crosslinked polyetylene insulated and external protection.10kV high tension cable, after energising, the electric field intensity in cable insulation is relatively big, and any structure designs improper, manufacturing defect or installation and operation is incorrect, all can cause cable breakdown, it is impossible to normally use；In cable making process, insulation to ensure not pollute, if there is impurity or bubble in Jue Yuan, then is easy to puncture after cable energising；If cable has moisture to enter the insulation of cable in running, then the life-span of cable can be substantially reduced；The structure (milliken conductor) being stitched together conductor polylith the to be used conductor of bigger specification cable, to reduce the kelvin effect of electric energy transmitting procedure, improves the transmission capacity of cable, can improve cable flexible simultaneously, it is simple to bending；Structure designs the water proofing property of cable to be taken into full account, it is ensured that during cable uses, moisture can not be to the possibility of cable internal penetration；Lay in running and do not limited by height fall, easy to maintenance；Owing to this cable is used for densely populated big city, fire resistance is also necessary, to reduce the generation of fire, there is also the problem that electric stress is concentrated, and prior art can not meet above demand.
Utility model content
Technical problem to be solved in the utility model there is provided the 8.7/10kV and following single high voltage power cable that a kind of manufacturing process is simple, reasonable price, length in service life, flexibility are good, water resistance is good, cooling performance is good, security performance is high.
A kind of 8.7/10kV described in the utility model and following single high voltage power cable, the center of described cable is provided with an insulated wire cores, conductor shield is extruded outside insulated wire cores, it is externally provided with stress control tube at conductor shield, outside stress control tube, extrudes elastic cord breaker, non-woven fabrics water blocking layer and armor successively；It is externally provided with cooling tube at armor, outside cooling tube, scribbles anticorrosive coat, outside anticorrosive coat, extrude outer protective polyethylene set；Described insulated wire cores is made up of conductor and the crosslinked polyetylene insulated layer that is extruded in outside conductor.
Improving further, described conductor is the milliken conductor of 5 pieces of fan-shaped aluminium conductor formation stitched together.
Improving further, described conductor shield is identical with conductor structure, is formed by 5 pieces of single fan-shaped shields are stitched together.
Improving further, described stress control tube is made up of non-linear resistance material, and it is put up no less than 20mm with insulation screen.
Improve further, described armor and anticorrosive coat to be shaped as irregular roundness ring-like.
The beneficial effects of the utility model are:
1, conductor of the present utility model is the milliken conductor of 5 pieces of fan-shaped aluminium conductor formation stitched together, cable is made to have more preferable flexibility, it is more conducive to bending, the most corresponding conductor shield is also adopted by same frame mode, 5 corresponding 5 fan-shaped aluminium conductors of single shield, it is achieved man-to-man form shields.
2, this utility model is provided with stress control tube, it is that a kind of specific insulation is moderate, the heat-shrinkable tube of the special electrical parameter that dielectric constant is bigger, electric parameter is utilized to force the stress evacuating of insulation shield incision position to become along the more uniform distribution of stress tube, process electric stress concentration problem in cable, and control to alleviate electric field stress and concentrate, light, install easily, performance good.
3, when high tension cable is by external impact force, elastic cord breaker can effectively buffer from extraneous pressure, and well protection core is without damage.
4, this utility model wrapped non-woven fabrics electricity waterstop, multilamellar semiconductor waterstop soft, and meet water and can expand rapidly, can the entrance of blocks moisture effectively, extend cable service life.
5, this utility model is provided with cooling tube, balance will be reached around the whole circumference of cooling tube by the heat transfer of the wall of cooling tube, and realize the cooling liquid that efficient heat is delivered to be disposed in cooling tube so that the heat minimizing that cable is overall, reduce kelvin effect；And outside cooling tube, scribble Colophonium anti-corrosion material, prevent cooling tube from being corroded and boring a hole.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, a kind of 8.7/10kV described in the utility model and following single high voltage power cable, the center of described cable is provided with an insulated wire cores, conductor shield 3 is extruded outside insulated wire cores, it is externally provided with stress control tube 4 at conductor shield, outside stress control tube, extrudes elastic cord breaker 5, non-woven fabrics water blocking layer 6 and armor 7 successively；It is externally provided with cooling tube 8 at armor, outside cooling tube, scribbles anticorrosive coat 9, outside anticorrosive coat, extrude outer protective polyethylene set 10；Described insulated wire cores is made up of conductor 1 and the crosslinked polyetylene insulated layer 2 that is extruded in outside conductor.
