Abstract
The utility model discloses a high-strength tensile water-resisting corrosion-resistance high-voltage cable. The cable is suitable for high-fall moist construction areas such as coal mining and long piled wharf construction areas. The cable comprises a conductor, a semi-conductive wrapping tape, a conductor shielding layer, a cross linked polyethylene (XLPE) insulating layer, an insulation shielding layer, a semi-conductive water-resisting tape, a copper wire shielding layer, a semi-conductive water-resisting tape, metal armoring layers and a high-density polyethylene (HEPE) outer sheath and an outer semi-conductive layer which are arranged from inside to outside sequentially, wherein the metal armoring layers are zinc-coated steel wire armors, and are of a zinc-coated steel tape reverse fastening structure, and zinc and steel form an original battery, and the zinc is adopted as the anode of the original battery. According to the high-strength tensile water-resisting corrosion-resistance high-voltage cable of the utility model, the zinc-coated steel wire armors and the steel tape reverse fastening structure are adopted, and therefore, it can be ensured that the cable can completely bear self weight and the effect of an external pull force when the cable is arranged in a high-fall site, as a result, the cable itself can be well protected; and the zinc and the steel form the original battery, and the zinc is adopted as the anode of the original battery, and therefore, the steel can be prevented from being corroded, and has excellent anti-corrosion performance, and can be an excellent waterproof and corrosion-resistance material.
Description
Technical field
The utility model relates to a kind of high-tension cable, specifically a kind of high-strength tensile corrosion-resistant high-tension cable that blocks water.
Background technology
Electric wire is in order to transferring electric power, a class electrician wire product of transmission information and the conversion of realization electromagnetic energy, and its medium and high voltage cable generally is mainly the cable of electric energy transmitting.
The structure of high-tension cable is generally: conductor, conductor screen, insulation, insulation shielding, metallic shield and oversheath etc.But this high-tension cable is owing to be subjected to strong mechanical constraints, is applicable to buried or pipeline, water in air is flat lays.
During high-drop installation, cable is because when being laid by the effects such as self gravitation, extraneous mechanical pulling force, and the intensity of cable, resistance to tension etc. are had relatively high expectations.Require cable when high-drop installation, not only can bear own wt and also want to bear certain external tensile force, thereby cable is played a protective role.
Block-water performance also is an important index considering high-tension cable, because very harmful to cable of moisture.Mechanical strength reduced after the metal armouring layer adopted ordinary metallic material to be subjected to cargo sweat, did not reach the effect of protection cable.Will cause the conductor oxidation if there is moisture to immerse, increase the energy loss of transmission line.Can produce the water tree after the crosslinked polyetylene insulated suction, so that operating cable occurs to puncture and damages.
But high-tension cable will use inevitably in high drop place, particularly when the relatively moist place of environment, makes for a long time the water infiltration unavoidable.
The utility model content
Technical problem to be solved in the utility model provides a kind of high-strength tensile corrosion-resistant high-tension cable that blocks water, and this high-tension cable has good anticorrosion, the characteristics such as high-strength tensile, and block-water effect is good.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of high-strength tensile corrosion-resistant high-tension cable that blocks water, be followed successively by from inside to outside conductor, semiconductive twining package tape, conductor shield, XLPE insulating barrier, insulation screen, semiconductive waterstop, shielding layer of copper wires, semiconductive waterstop, metal armouring layer and HDPE oversheath and outer semiconducting layer, described metal armouring layer is the zinc-coated wire armouring, and adopt galvanized steel strip oppositely to tighten structure, zinc and steel form primary cell, and zinc is as anode.
In order to obtain more high-intensity tensile characteristics, described metal armouring layer is three layers of zinc-coated wire armouring.
The utility model high-tension cable is suitable for the humidity construction area of coal mining, the contour drop of High-piled Wharf Construction, the zinc-coated wire armouring that this cable adopts, steel band is oppositely tightened structure, guaranteed that cable is when high-drop installation, fully can the load-bearing own wt and the effect of external tensile force, cable itself is played a very good protection; Zinc and iron and steel form primary cell, and zinc prevents steel corrosion as anode, has good anticorrosion, is outstanding waterproof, anticorrosive.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the applicable electric pressure of the utility model high-tension cable is 66～220kV, and it is followed successively by conductor 1, semiconductive twining package tape 2, conductor shield 3, XLPE insulating barrier 4, insulation screen 5, semiconductive waterstop 6, shielding layer of copper wires 7, semiconductive waterstop 8, metal armouring layer 9 and HDPE oversheath and outer semiconducting layer 10 from inside to outside.
Conductor 1 can adopt copper conductor or aluminium conductor, and copper wire or aluminium wire are filled material water-proof material and formed water-blocking conductor in stranded process.Vertical endosmosis for fear of water along cable adopts water-blocking conductor and the wrapped semiconductive of each layer wrapped.
This cable adopts the good PE material of Corrosion Protection as the first barrier, the core is metal armouring layer 9, and metal armouring layer 9 adopts galvanized steel material (zinc-coated wire armouring), utilizes the galvanized steel material to have good waterproof anti-corrosion, the characteristics such as high strength realize waterproof, anticorrosion; This respective outer side edges adopts the stranded rear steel band of steel wire oppositely to tighten technique, and implementation structure is stable not yielding, reaches the high-strength tensile effect.
In addition, zinc and iron and steel form primary cell, and zinc prevents steel corrosion as anode, has the characteristics such as good anticorrosion, high strength, is outstanding waterproof, anticorrosive.
Above-described embodiment limits the utility model never in any form, and every employing is equal to replaces or technical scheme that the mode of equivalent transformation obtains all drops in the protection range of the present utility model.
