For achieving the above object, the technical scheme of this utility model solution technical problem is:
A kind of 10kV overhead line conductor fixed structure, including aluminum cald steel wire, it is at least to be made preformed wiring by two aluminum cald steel wires, this preformed wiring forms arc section and the gaiter wire section of holding with a firm grip at U-bend head section, pin insulator neck groove by fixing for wire, and described preformed wiring is fixed the U-bend head section at wire and compressed doubling after wire；The neck groove prolonging pin insulator is wound into doubling again after opposite side, reverses the preformed wiring of doubling；The last preformed wiring that tightens is the gaiter wire section of holding with a firm grip and forms tubular helical and extend form.
It is additionally provided with insulating lacquer layer outside described every aluminum cald steel wire of preformed wiring.
Described pin insulator is P15 or P20 type pin insulator.
The described gaiter wire section of holding with a firm grip is at least wound around 5 circles.
Described preformed wiring also can use fixes arc section and the form of the gaiter wire section of holding with a firm grip at formation U-bend head section, pin insulator neck groove in pin insulator both sides simultaneously by wire.
This utility model compared with prior art has a following advantageous effect:
A kind of 10kV overhead line conductor fixed structure of the present utility model, stress suffered by wire is evenly distributed on a region the biggest, without harmful stress concentration point, it can reduce dynamic stress, prevent from disconnected stock phenomenon because of fatigue of materials, itself there is certain anti-vibration functions, the resistance to ability of shaking of wire can be improved.This utility model not only solves tradition, and wiring long-play is aging causes degradation problem under intensity, it is thus also avoided that because constructing technology problem causes technology for binding not pass a test, and its simple in construction, it is easy to install, a people just can the most free-hand complete to install；Installation quality concordance is good, full installation process will not damage wires, decrease tradition wiring and easily cause wire wear problem, corrosion resistance is strong, stable performance, still can be properly functioning at the environment running into extreme, grip never discharges, and reduces heavily contaminated area distribution line failure and occurs, improve electric power netting safe running coefficient, drastically increase the ability of the resistance to harmful stress of overhead transmission line.
