Manufacturer of overhead bare conductors

Description :

　　Steel cored aluminum stranded wire has the advantages of high conductivity, good thermal stability, low sag, and good self damping characteristics. With the continuous advancement of overhead transmission line technology, new types of wires with high strength, high conductivity, heat resistance, and low sag are constantly being developed.

　　1. The steel core bears all the mechanical loads of the wire, while the aluminum wire strand mainly contributes to carrying current but not mechanical loads. Therefore, the operating temperature of the wire is not limited by the softening characteristics of the aluminum wire strand. The operating temperature is completely determined by the softening characteristics of the steel core, and the recrystallization temperature of the steel core is higher, which allows it to maintain normal mechanical strength at higher temperatures.

　　2. ACSSTW has a smaller diameter, which can reduce wire icing and wind loads. The smaller diameter and smoother outer surface can reduce the aerodynamic coefficient and mitigate the hazards of light wind vibrations and dancing. Having a larger aluminum cross-sectional area can increase current carrying capacity and reduce wire loss. In addition, the smoother outer surface of the wire can also reduce the level of corona and radio interference.

　　3. It has good anti-corrosion performance and thermal stability, and there is no significant change in its ductility under high temperature working conditions. It also has sub damping characteristics, which are beneficial for reducing wind induced vibrations and minimizing line losses in transmission lines.

　　4. And it is a fully annealed aluminum with a conductivity of 63% IACS made of soft aluminum, and a low mechanical strength of only 59-76MPa, much lower than the mechanical strength of ordinary aluminum wire (160-200MPa).

　　Most of the performance advantages of ACSSTW steel core aluminum stranded wire are due to the use of fully annealed aluminum material in the wire strands. Such aluminum wire strands have low strength. When the wire is subjected to tension, the strain of fully annealed aluminum strands quickly enters the non elastic region of the stress-strain curve, causing irreversible deformation of the aluminum strands. The tension will be transferred entirely to the steel core.

　　Steel cored aluminum stranded wire is mainly used in medium and high voltage transmission lines. Due to the limited path of the line and the inability to install multiple lines on one road, people have come up with the idea of using one path, one iron tower, and hanging multiple steel cored aluminum stranded wires. That is, one line is equivalent to installing multiple lines; For 220KV, 500KV, 800KV, and 1000KV lines, China adopts the method of hanging four or six wires (four wire, six wire method), which is called the same tower and parallel installation.

　　Steel cored aluminum stranded wire with high conductivity JL price advantage: Steel cored aluminum stranded wire has characteristics such as tensile strength and expandable tower distance. Therefore, it is widely used in overhead transmission and distribution lines of various voltage levels, with simple structure, easy installation and maintenance, low line cost, large transmission capacity, and long distance, which is also conducive to the installation of crossing special geographical conditions such as rivers and valleys; Has good conductivity and sufficient mechanical strength to resist.
