Embodiment Construction

[0016] Referring to accompanying drawings 1-3, the low-sag annealed aluminum wire is composed of a core and a conductor, and a conductor is arranged outside the core 3 that is loaded. The low-sag annealed aluminum conductor adopts a concentric twisted structure of round wire and molded wire.

[0017] Referring to accompanying drawing 1, the low-sag annealed aluminum wire is composed of a core and a conductor, and a conductor 2 and a conductor 1 are arranged on the outside of the loaded core 3 . Both the conductor 1 and the conductor 2 are wires composed of single wires with a circular cross section.

[0018] Referring to accompanying drawing 2, the low-sag annealed aluminum wire is composed of a core and a conductor. Both the conductor 4 and the conductor 5 are wires composed of monofilaments with special-shaped cross-sections.

[0019] Referring to accompanying drawing 3, the low-sag annealed aluminum wire is composed of two parts, a core and a conductor, and a conductor 6 ...

Abstract

The invention relates to a low-sag annealed aluminum wire, in particular to a special cable for overhead power transmission line, which is applicable to the construction and reforming of overhead transmission lines. The invention comprises two parts, namely, a core and a plurality of conductors; wherein, the conductors are arranged outside the load-bearing core, and the conductors adopt full annealed aluminum wire with a conductivity of 63% IACS; besides LB10 super high strength aluminum-clad wire or EST super high strength galvanized steel wire, the load-bearing core also adopts G3A super high strength galvanized steel wire or carbon fiber composite materials. The cable is in the composite structure with circular wire or shaped conductor, or with single circular wire and shaped conductor.

Description

technical field [0001] The low-sag annealed aluminum conductor of the invention relates to a special conductor for overhead power transmission lines, and is suitable for newly constructed overhead power transmission lines and transformation of overhead power transmission lines. Background technique [0002] With the rapid development of my country's national economy, the demand for electricity has increased significantly, and the original transmission lines that have been operating at full capacity can no longer meet the demand. Overhead transmission wires are the necessary carriers to transmit electric energy from the power generation end to the power reception end. While transmitting electric energy, it also consumes part of the energy. The original steel-cored aluminum stranded wire has a continuous use temperature of 70-80°C, and the transmission capacity is limited. Contents of the invention [0003] The object of the present invention is to provide a low-sag annealed...
