The use of steel core aluminum stranded wire need to pay attention ...

Steel core aluminum stranded wire is mainly composed of steel wire and aluminum wire, mainly used for overhead line transmission power. In the meantime, the primary role of aluminum wire is to transmit electricity, and the primary role of steel wire is to strengthen the stability and strength of the line.

Ziyu are exported all over the world and different industries with quality first. Our belief is to provide our customers with more and better high value-added products. Let's create a better future together.

What are the precautions in the use of steel core aluminum stranded wire?

First of all, we should pay attention to the problem that it can reach or accept the maximum voltage. Before purchasing or equipment, fully understand the voltage and current that need to be transmitted, and then choose the model that matches it.

Secondly, the safety of the equipment process is also very important, because it is usually applied to the transmission project of overhead lines, so it is necessary to have professional equipment personnel to carry out the equipment according to the time, which can not only ensure the safety of the personnel in the equipment process, but also reasonable equipment, pre-designed safe distance from buildings or trees, etc.

When the equipment uses the steel core aluminum stranded wire, as long as all the details are fully considered, the power can be transmitted normally to ensure its future safety.

Steel core aluminum stranded wire is a kind of common wire and cable. A wide range of applications, especially for cables. Choosing the right wire and cable is the condition to ensure safe use of electricity. In the choice, to consider can withstand the use, laying conditions and safety planning. To consider heat, voltage loss, economic current density, mechanical strength and other conditions.

According to experience, low-voltage power lines due to the large load current, the general selection of cross-section according to the heating situation, and then check its voltage loss and mechanical strength; low-voltage lighting lines on the voltage level requirements are higher, according to the allowable voltage drop to select the cross-section of the line, and then check its heating and allowable voltage drop. The mechanical strength of high voltage overhead lines should also be checked.

However, in general, ACSR is suitable for various line requirements. Copper conductor has a strong conductive function, the wire will not be simple heat, the joint will not be simple loose, will not simply cause a fire.

Steel core aluminum stranded wire has been widely used and is also very common in our life. Therefore, it is natural to know more about it in order to give more benefits and convenience. What good is it?

One of the advantages of the steel core aluminum stranded wire is that the structure is simple, so it is easier to use and does not require too many tedious processes. Secondly, the advantage is that the quotation is relatively low, and the cost of all projects will be reduced during application, so it is naturally widely used, and maintenance is also easy, and there will not be too much trouble in the local area.

A third advantage of ACSR is the relatively large transmission capacity. Compared with other strands, this feature is very obvious, so this feature also lays a solid foundation for its development. These are the benefits of this kind of stranding. At the time of use, you can make reasonable choices based on these benefits, which in turn brings more benefits.

First, the material is different

The company is the world’s best Steel Core Aluminum Stranded Wire supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Aluminium clad steel is steel as the core material, outsourced with aluminium or aluminium alloy, belongs to a kind of outsourced aluminium products. Steel core aluminium stranded wire is made of multi-stranded aluminium and steel core stranded into an alloy cable.

Second, the structure is different

Aluminium clad steel by the aluminium layer and the steel core of two layers, steel core aluminium stranded wire is composed of steel core and aluminium core strands. Among them, each core strand by many twisted strands of steel wire and aluminium wire stranded into.

Third, the use of different

Aluminium clad steel is mainly used for transmission lines, traction power boosting equipment, as well as ground and power communication lines. And steel core aluminium stranded wire is mainly used in high-rise buildings, underground, light rail and power engineering.

Four, performance comparison

Aluminium clad steel is characterized by the same size and weight, its transmission performance is better than pure aluminium wire, and has a certain strength and corrosion resistance. The steel core aluminium stranded wire is characterized by high strength and good electrical conductivity, and relatively light, can reduce the cost of power engineering.

Fifth, the installation is different

Aluminium clad steel installation is relatively simple, the installation can be used to hang, bare copper grounding or insulator pole and other ways. The installation of steel-core aluminium stranded wire is more complex, need to use special connectors and joints to connect multiple core strands.

Conclusion

Although aluminium-clad steel and steel-core aluminium stranded wire are easy to be confused externally, in fact, there are obvious differences in their materials, structure, use, performance and installation methods. It is necessary to choose the appropriate material according to the actual needs in order to achieve the best power transmission effect.
