Abstract
The utility model discloses an energy-saving expanded lead, comprising an expanded unit arranged in the lead and a conductor material twisted outside of the expanded unit, wherein the expanded unit comprises a hollow aluminium-alloy wire and the conductor material is an aluminium material. By adopting the hollow aluminium-alloy wire to be a structure of the expanded unit, weight is light, conductivity is good and a structure is stable and is easy to bend.
Description
Technical field
The utility model relates to a kind of aerial condutor, particularly a kind of energy-saving expanded conductor.
Background technology
Along with the national economy develop rapidly, Electricity Demand rapidly increases, and according to the strategic plan of " transferring electricity from the west to the east, north and south supplies mutually, national network ", construction remote, the large capacity transmission circuit is imperative.These all require to improve transmission voltage, thereby will greatly improve the specification requirements such as electric field, magnetic field, audible noise and radio interference level of transmission line.Expanded conductor has larger diameter, and electric property is better.Satisfying under the prerequisite of line project, using expanded conductor can save conductor material, and then reducing steel tower load and construction weight.
Mainly contain at present two kinds of hole enlargement modes: a kind of is to dredge the geometric pattern expanded conductor, be mainly to extract some single lines out to reach the hole enlargement purpose in original common lay configuration, but this hole enlargement mode structural stability is poor, easily jumps thigh at unwrapping wire; Another is to utilize the tubular support core to come hole enlargement, and the shortcoming of this hole enlargement mode is that supporting-core is not easy bending, easily distortion.
The utility model content
The purpose of this utility model is to solve the problem that prior art exists, and provides a kind of providing to conduct electricity very well, and the flexible energy-saving expanded conductor of Stability Analysis of Structures.
The technical scheme that realizes the utility model purpose is a kind of energy-saving expanded conductor, comprises being positioned at inner hole enlargement unit and stranded in the conductor material of outside, hole enlargement unit; Described hole enlargement unit comprises the hollow aluminium alloy line; Described conductor material is aluminum.
Described hole enlargement unit also comprises steel core; It is outside that described hollow aluminium alloy line is stranded in described steel core.
Described hole enlargement unit also comprises hollow metal tube; It is outside that described hollow aluminium alloy line is stranded in described steel core hollow metal tube.
Adopted technique scheme, the utlity model has following beneficial effect: the utility model adopts the hollow aluminium alloy line as the structure of hole enlargement unit, lightweight, good conductivity, and Stability Analysis of Structures is flexible.
