Product Introduction

With the improvement of transmission technology and the development of transmission and transformation lines, the advantages of aluminum magnesium silicon high-strength aluminum alloy series stranded wires are becoming increasingly apparent.

Advantages:

High strength, light weight, and low sag can increase the distance or decrease the height of the iron tower, reducing land occupation and construction costs of the line.

Aluminum alloy has a hard surface, resistance to compression, easy wire connection, high construction efficiency, and is not easily worn or scratched during installation. It can reduce corona losses and minimize interference of transmission lines with radio waves

- Good creep resistance

Corrosion resistance and long service life

Product Introduction

Heat resistant aluminum alloy stranded wire and high-strength steel core heat resistant aluminum alloy stranded wire are wires made by twisting heat-resistant aluminum alloy round wire and high-strength galvanized steel stranded wire. With the rapid development of the national economy and the continuous improvement of people's level, the demand for electricity has increased sharply, and transmission lines are increasingly developing towards large capacity, which requires increasing the transmission capacity of wires. As a high-performance special conductor, heat-resistant aluminum alloy has good advantages in urban network renovation, substation construction, and general power lines in China.

characteristic:

1. The long-term working temperature is 150 ℃, and the short-term temperature can reach 180 ℃, which allows the continuous allowable current carrying capacity to be 1.5-1.6 times that of ordinary ones of the same specifications

At room temperature, it has the same strength as ordinary stranded wire, and the strength remains above 90% during high temperature operation.

3. Whether at room temperature or high temperature, it maintains the same degree of creep resistance as ordinary aluminum wire.

4. There is no significant difference between the laboratory smoke test and outdoor atmospheric exposure test.

Usage scenario:

1. It is particularly suitable for use as a busbar for high current transmission in substations, power plants, etc. Can save engineering investment.

In the expansion and renovation project of urban power lines, especially in areas with narrow corridors, it is only necessary to replace wires with similar cross-sectional specifications, and there is basically no need to replace iron towers, which can meet the requirements of strength and wire to ground relaxation.

3. In a dual circuit circuit, it can also temporarily carry the current carrying capacity of another circuit, facilitating emergency repair and maintenance in case of circuit accidents.

4. On the new line, the use of heat-resistant aluminum alloy wires simplifies the line structure and has great benefits for the safe operation of the line.

Execution standards:

1. Heat resistant aluminum alloy stranded wire and high-strength heat resistant aluminum alloy stranded wire shall comply with Q/ZJ3-2008 standard for heat resistant aluminum alloy round wire

2. High strength galvanized steel wire for heat-resistant aluminum alloy stranded wire shall comply with the GB/T3428-2012 standard (equivalent to IEC60888:1987 standard)

Heat resistant aluminum alloy wire products comply with Q/ZJ4-2008
