Abstract

An environmentally friendly light anti-corrosion steel-cored aluminum stranded wire, including a core wire and an outer conductive bare wire, the core wire is a multi-strand galvanized steel wire, and the conductive bare wire is several layers of aluminum wire twisted outside the core wire. There is a high-density polyethylene anti-corrosion layer between the core wire and the conductive bare wire. The utility model has strong anti-corrosion performance, no overflow of anti-corrosion grease during use, and good environmental protection performance. It is suitable for erection in coastal areas, areas with heavy industrial pollution or salt spray, is not easy to be corroded, and has a long service life. The outer diameter and unit weight of the utility model are almost the same as those of ordinary steel-reinforced aluminum stranded wires of the same specification. Therefore, the existing pole and tower resources can be fully utilized for laying and installation, and the cost of the pole and tower can be reduced.

Description

Environmentally friendly light anti-corrosion steel core aluminum stranded wire

technical field

The utility model relates to a wire, in particular to a steel-cored aluminum stranded wire for transmitting electric energy in power transmission and distribution lines.

Background technique

The steel-cored aluminum stranded wires used to transport electric energy in the existing transmission and distribution lines, especially the steel-cored aluminum stranded wires erected in coastal areas, areas with heavy industrial pollution or heavy salt spray, are easily corroded by various corrosive gases. In order to enhance the anti-corrosion performance, it is generally adopted to apply anti-corrosion grease to the steel core, and the anti-corrosion grade is mainly light anti-corrosion. Although the anti-corrosion grease has a certain anti-corrosion effect, the anti-corrosion effect is not ideal due to the influence of the unevenness, discontinuity and grease overflow of the grease coating.

Contents of the invention

In order to overcome the deficiencies of the existing steel-cored aluminum stranded wires for transmitting electric energy in the existing power transmission and distribution lines, the utility model provides an environmentally friendly light anti-corrosion steel-cored aluminum stranded wire, which has strong anti-corrosion performance, no overflow of anti-corrosion grease during use, and is environmentally friendly. Good performance.

The utility model provides an environment-friendly light anti-corrosion steel-cored aluminum stranded wire, which includes a core wire and an outsourced conductive bare wire. The core wire is a multi-strand galvanized steel wire. There is a high-density polyethylene anti-corrosion layer between the outer aluminum wire and the core wire and the conductive bare wire.

The beneficial effects of the utility model are: strong anti-corrosion performance, no overflow of anti-corrosion grease during use, good environmental protection performance, suitable for erection in coastal areas, areas with industrial pollution or heavy salt spray, not easily corroded, and long service life. The outer diameter and unit weight of the utility model are almost the same as those of ordinary steel-reinforced aluminum stranded wires of the same specification. Therefore, the existing pole and tower resources can be fully utilized for laying and installation, and the cost of the pole and tower can be reduced.
