Abstract
Disclosed is a 10-20 kV aerial insulated cable, mainly solving the problems that conventional aerial insulated cables are easy to cause electric leakage and short circuit, poor in safety performance, and short in service life. The aerial insulated cable comprises a core wire (1) and an insulating layer (2), and is characterized in that: the core wire (1) is formed by intertwisting a plurality of leads (3); the core wire (1) is externally and spirally wound by a shielding layer (4); and the shielding layer (4) is externally and tightly coated by the insulating layer (2). The cable is characterized by being good in insulating property, long in service life, and safe and reliable to use.
Description
Technical field
The utility model relates to a kind of insulated aerial cable, is specifically related to a kind of 10-20kV aerial insulated cable.
Background technology
At present, insulated aerial cable has insulation property and certain resistance to corrosion, can effectively avoid phase fault and ground fault, is widely used in power distribution network.Existing insulated aerial cable generally adopts the structure of heart yearn outside coated insulation layer, and it is aging to use for a long time insulating barrier easily to occur, and causes the insulation property of insulated aerial cable to reduce, and leaks electricity, the phenomenon such as short circuit poor safety performance, the weak point in useful life of cable.
The utility model content
In order to overcome the deficiency of background technology, the utility model provides a kind of 10-20kV aerial insulated cable, and this cable has good insulation preformance, long service life and safe and reliable characteristics.
The technical solution of the utility model is: this 10-20kV aerial insulated cable, comprise heart yearn and insulating barrier, and heart yearn forms by multiple conducting wires is stranded, and the heart yearn external spiral is wound with screen, the outer closely coated insulation layer of screen.
Described wire is 7 or 19.
Described insulating barrier is crosslinked polyethylene.
The beneficial effects of the utility model are: owing to take such scheme, increased screen, and the structure by spiral winding, adopt the screen of bar shaped to get final product, easy to process, the more important thing is the insulation property that improved cable, during long-time the use, can not occur after insulating barrier is aging leaking electricity or the phenomenon of short circuit yet, safe and reliable, long service life.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is A-A structure cutaway views among Fig. 1.
1-heart yearn among the figure, 2-insulating barrier, 3-wire, 4-screen.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Figure 1 and Figure 2, this 10-20kV aerial insulated cable comprises heart yearn 1 and insulating barrier 2, and heart yearn 1 is by multiple conducting wires 3 stranded forming, and heart yearn 1 external spiral is wound with screen 4, screen 4 outer tight coated insulation layers 2.Owing to take technique scheme, increased screen 4, and the structure by spiral winding, adopt the screen 4 of bar shaped to get final product, easy to process, the more important thing is the insulation property that improved cable, during long-time the use, can not occur after insulating barrier 2 is aging leaking electricity or the phenomenon of short circuit yet, safe and reliable, long service life.
Described wire 3 is 7 or 19.The quantity of wire 3 is determined according to conductive capability.
Described insulating barrier 2 is crosslinked polyethylene.Insulating barrier 2 adopts conventional insulating material, and cost is lower.
Claims (3)
1. 10-20kV aerial insulated cable, comprise heart yearn (1) and insulating barrier (2), it is characterized in that: heart yearn (1) is by stranded the forming of multiple conducting wires (3), heart yearn (1) external spiral is wound with screen (4), the outer closely coated insulation layer (2) of screen (4).
2. 10-20kV aerial insulated cable according to claim 1, it is characterized in that: wire (3) is 7 or 19.
