Aluminum core reinforcement is a product twisted by single-layer or multi-layer aluminum wires. In the process of use, its structure is very simple to ensure that its installation time can be greatly reduced, which provides convenience for our life.
As for transmission, its transmission capacity is very large. Both the rivers and lakes across the sea can constantly change according to the special terrain, and the availability of space has been greatly appreciated by people.
On the other hand, steel cored aluminum strand is very good under the above technical conditions, so its economic benefit is very large. Such a high price is due to the fact that users can get more products. It is the most suitable product for use both technically and economically.
Aluminum conductor steel reinforced (ACSR) conductor brings together the best elements of two materials – aluminum and steel.
The combination of the two makes use of the excellent conductivity of aluminum and the strength of steel. ACSR has aluminum fibers surrounding a stainless steel core. The composition of the cable and the percentage of each metal can be modified to meet the requirements of different applications.
ACSR cable is simple in structure. The lightness of aluminum facilitates easy installation and system maintenance.
The cost of setting aluminum core steel reinforcing wire is low. At the same time, the transmission capacity is large.
These cables have excellent tensile strength (which means that they can be used over a larger span without a lot of support), sufficient mechanical strength, applicability of cross voltage level, and suitability for overhead transmission and distribution lines (versatility). Most importantly, ACSR conductor has an absolute advantage in use, so the price must be your focus.
Almost every performance aspect of aluminum conductor steel reinforced cable is excellent. The rebound of this cable is very small. They have a high degree of flexibility, and the bending properties of this conductor are very satisfactory.
ACSR cables are popular because they greatly improve the performance of aluminum conductors. Although aluminum is light and has excellent conductivity, it is not particularly suitable for applications requiring strength. The steel bar with steel core solves this problem.
Even if the steel cored aluminum strand is overloaded and overheated for a long time, it will produce high-strength creep resistance. The stability of the connection is guaranteed, indicating the reliability of the conductor.
ACSR cable also has a long service life. Aluminum fiber has high corrosion resistance. There is sufficient evidence that aluminum can withstand some of the worst environments, so it has been widely used in industrial and marine facilities.
Flexibility and personalization options
ACSR conductors provide a lot of versatility. There are different aluminum / steel combinations and different designs.
For example, the trapezoidal line is different from the standard variety because it takes up less space. This shape appeared in the 1980s and was originally called compact ACSR conductor.
The twisted pair (TP) ACSR conductor has two sub conductors wound around each other. The functional advantage comes from its shape and its ability to prevent ice or wind – a typical problem with circular cables.
In addition to this flexibility, ACSR cables can have a series of coatings that will again be used for functional purposes. Some conductor coatings are characterized by high thermal radiation emissivity and relatively low absorption of ultraviolet light. By applying such coatings, the rating of aluminum core steel reinforced cables can be improved. This occurs because the ACSR cable temperature decreases at the same amperage because the heat dissipation effect of the special coating is much better.
