The insulation aerial cable of the utility model comprises a single insulation conduct wire or is twisted by multiple insulation conduct wires, and the single insulation conduct wire respectively comprises a strengthen core twist body, an anticorrosive lubricant grease layer, an aluminum twist wire layer and an insulating layer from inside to outside. Certain intervals are arranged between the aluminum twist wire layers, the aluminum twist wire layers and the strengthen core twist bodies smeared with the anticorrosive lubricant grease layer, a single aluminum wire in the aluminum twist wire layer is cuneate, the strengthen core twist bodies are made of multiple galvanized steel wires or aluminum alloy wires, and the number of layers of the aluminum twist wire layers can be ascertained by the transmission capacity of the line. When the utility model insulation aerial cable is twisted by multiple insulation conduct wires, the insulating layer of each insulation conduct wire is provided with salient ridges of different number for phase-sequence identification. The utility model can increase the assurance coefficient of output lines and avoid various accidents caused by strong vibration breaking or fatigue breaking of the aerial cable conductor in the circuit.
Description
Technical field:
The utility model relates to a kind of aerial cable, belongs to insulated aerial cable and makes the field.
Background technology:
Domestic insulated aerial cable is classified from the material of conductor at present, can be divided into copper core aerial cable, aluminium core aerial cable, aluminium alloy insulated aerial cable, steel core insulated aerial cable and the reinforced insulated aerial cable of high strength alumin ium alloy etc.The conductor of these aerial cables is tight stranded type structure, and insulating barrier or screen and the insulating barrier that extrudes arranged at conductive surface; These aerial cables are because all closely contacts mutually between from the conductor body to the insulating barrier, therefore, after aerial cable is laid, when external force such as being subjected to wind-force is done the time spent, aerial cable between tower bar and the tower bar can whole vibrate, even produce resonance with the external force effect, can cause cable conductor to take place to shake by force disconnected strand or tired disconnected strand, and a disconnected burst position will be as electric field and stress concentration point, thereby very fast meeting is destroyed and cause opening circuit power outage and even personal safety accident cause heavy economic losses.
Summary of the invention:
The utility model is the above-mentioned defective at prior art, provides a kind of from the vibration damping insulated aerial cable, avoids cable conductor to take place to shake by force disconnected strand or tired disconnected strand and produce various accidents.
The technical solution of the utility model: insulated aerial cable of the present utility model is by single insulated conductor or thoroughly do away with edge bundle conductor strand more and form.The structure of single insulated conductor from inside to outside is strengthening core intertwist body, cosmoline fat layer, aluminium stranded conductor layer, insulating barrier successively.Between aluminium stranded conductor layer and the aluminium stranded conductor layer, aluminium stranded conductor layer and be coated with between the strengthening core intertwist body of cosmoline fat layer certain interval is arranged.The single aluminum steel of aluminium stranded conductor layer is wedge shape.
The strengthening core intertwist body is by many galvanized steel wires or aluminium alloy wire is stranded forms.The number of plies of aluminium stranded conductor layer can be determined according to the transmission capacity of circuit.
When insulated aerial cable of the present utility model is formed by many eradications edge bundle conductor strand, the convex ridge that is used for the phase sequence sign of different numbers is arranged on the insulating barrier of every eradication edge lead.
The utlity model has following beneficial effect:
1, between the aluminium stranded conductor layer of the utility model insulated aerial cable, aluminium stranded conductor layer and be coated with between the strengthening core intertwist body of cosmoline fat layer certain interval is arranged, when aerial cable is being subjected to external force such as wind-force and is producing vibration, because gapped existence, the vibration frequency of each layer of cable has nothing in common with each other and the phase mutual interference, thereby the energy that can consume external force vibration automatically reaches the effect of damping, improve the coefficient of safety of transmission line, avoid causing economic loss;
2, outside the strengthening core intertwist body, apply cosmoline fat layer, can prevent impact wear and electrochemical corrosion between the strengthening core intertwist body that causes because of vibration and the aluminium stranded conductor layer effectively, when the strengthening core intertwist body is the zinc-coated wire intertwist body, zinc coat be had the certain protection effect simultaneously;
3, the aluminum steel of aluminium stranded conductor layer of the present utility model is wedge shape, and conductive surface rounding smoothness is higher, the even electric field of conductive surface;
4, in cable center the strengthening core intertwist body is set, has improved the whole tension cutting capacity of cable greatly, can increase the distance between erecting cable tower bar and the tower bar, thereby save laid down cost.

Embodiment:
Further specify execution mode below in conjunction with accompanying drawing.The structure of unit cable conductor of the present utility model as shown in Figure 1 from inside to outside is strengthening core intertwist body (1), cosmoline fat layer (2), aluminium stranded conductor layer (3), insulating barrier (4) successively.Strengthening core intertwist body (1) is by many galvanized steel wires or aluminium alloy wire is stranded forms.The number of plies of aluminium stranded conductor layer (3) can be determined according to the transmission capacity of circuit.Between aluminium stranded conductor layer (3) and the aluminium stranded conductor layer (3), aluminium stranded conductor layer (3) and be coated with between the strengthening core intertwist body (1) of cosmoline fat layer (2) certain interval (5) is arranged.The single aluminum steel of aluminium stranded conductor layer (3) is wedge shape.
As shown in Figure 2, the utility model can be single insulated conductor, also can be that the edge bundle conductor strands of thoroughly doing away with form more.Needs according to concrete circuit are selected.When insulated aerial cable of the present utility model is formed by many eradications edge bundle conductor strand, the convex ridge (6) that is used for the phase sequence sign of different numbers is arranged on the insulating barrier of every eradication edge lead.
Claims (2)
1, the utility model is a kind of from the vibration damping insulated aerial cable, it is by single or thoroughly do away with the edge conductor more and form, its single insulated electric conductor structure from inside to outside is strengthening core intertwist body, cosmoline fat layer, aluminium stranded conductor layer, insulating barrier successively, it is characterized in that: between aluminium stranded conductor layer and the aluminium stranded conductor layer, aluminium stranded conductor layer and be coated with between the strengthening core intertwist body of cosmoline fat layer certain interval is arranged; The single aluminum steel of aluminium stranded conductor layer is wedge shape.
