Steel core aluminum stranded wire is a common conductor material, which is widely used in power transmission, overhead lines and other fields. It is mainly composed of steel core and aluminum stranded wire, which has excellent electrical conductivity and mechanical properties. The following are some technical parameters about ACSR:

1. conductor structure

The steel-core aluminum stranded wire usually adopts a multi-layer stranded structure, with a steel core inside and an aluminum stranded wire wrapped outside. This structure enables the wire to have both good compressive resistance and good electrical conductivity.

2. conductor material

1. Steel core: generally made of high-quality carbon steel or alloy steel, with high strength and good corrosion resistance.
2. Aluminum stranded wire: made of high purity aluminum, with good conductivity and light characteristics.

3. technical parameters

1. Rated current carrying capacity: According to the cross-sectional area and length of the conductor, the ACSR has a certain rated current carrying capacity. Its current carrying capacity depends on the resistance of the wire, temperature, length and other factors.
2. Resistivity: The resistivity of aluminum is low, so the resistance of ACSR is relatively low, which is beneficial to improve the efficiency of power transmission.
3. Tensile strength: The existence of the steel core makes the steel core aluminum strand have higher tensile strength and can withstand greater tension.
4. Bending performance: ACSR has good bending performance and can adapt to the needs of different bending angles.
5. Corrosion resistance: The steel core is made of corrosion-resistant materials, which makes the steel core aluminum stranded wire have good durability in harsh environments.
6. Insulation performance: The surface of ACSR is usually covered with an insulating layer to improve its insulation performance and ensure the safety of power transmission.
7. Length: Customized according to requirements, the common ones range from tens of meters to thousands of meters.

4. other parameters

In addition, the steel core aluminum strand has parameters such as outer diameter, number of roots, and stranding direction, which also affect the performance and use of the wire.

In short, the steel core aluminum stranded wire has excellent electrical conductivity and mechanical properties, and is widely used in power transmission, overhead lines and other fields. Its technical parameters include rated current carrying capacity, resistivity, tensile strength, bending performance, corrosion resistance, insulation performance and other aspects. Users need to consider according to actual needs when selecting and using. The above information is for reference only, if necessary, it is recommended to consult the relevant industry standards or consulting professionals.
