The term ACSR stands for “steel cored aluminum conductor”. It is a stranded conductor, including many aluminum conductor layers on the simulated steel wire core. The steel wire core here is a single steel wire depending on the size. These can be used for different zinc coatings, such as grade A, B and C, to protect against corrosion. In this conductor, the number of aluminum and steel can be selected according to the current carrying capacity and mechanical strength of the application. These conductors can be identified according to the characteristics of reliability, economy, economy, weight ratio and positive strength. This paper summarizes what is steel cored aluminum strand, its type and working principle.
What is steel cored aluminum strand?
Definition: ACSR is a kind of large capacity stranded conductor, which is mainly used for overhead power lines. The design of steel cored aluminum strand can be done in this way. The outside of the conductor can be made of pure aluminum material, while the inside of the conductor is made of steel material, so as to provide additional strength to support the weight of the conductor. Compared with aluminum, steel material has higher strength, so mechanical force can be applied to the conductor. The service life of steel materials used in conductors can be extended by galvanizing or coating other materials. This prevents corrosion on the material. The diameters of steel and aluminum can be changed according to the type of ACSR conductor.
The size of steel cored aluminum strand is limited, and there are many sizes to choose from, including single core or multi-core steel wire. Generally speaking, a large number of aluminum strands. Nevertheless, some types of conductors have a large number of steel strands compared to aluminum strands. The part of ACSR can be identified by its stranding.
Steel cored aluminum strand type
In energy transmission, copper wires have been used many years ago, but at present, AI wires have replaced these copper wires because of their low price and large diameter compared with copper.
Steel cored aluminum strand (ACSR)
The steel cored aluminum strand is filled with steel. High strength ACSR conductor is suitable for overhead ground wire, devices related to ultra long span and river crossing. These materials have different tensile strength. Due to the large diameter, a higher radiation limit can be obtained.
Where to use ACSR cable: aluminum core steel cable (ACSR) is a high-capacity, high-strength stranded conductor, which is usually used in overhead power lines. The outer strand is high-purity aluminum, which is selected because of its good conductivity, light weight and low cost. The steel cored aluminum strand is filled with steel. High strength ACSR conductor is suitable for overhead ground wire, devices related to ultra long span and river crossing. These materials have different tensile strength. Due to the large diameter, a higher radiation limit can be obtained. This provides additional power to the conductor to support the weight of the conductor. Compared with aluminum, steel has higher strength. Therefore, it can be applied to mechanical force carrier. In order to prolong the service life of the conductor, it can be coated with zinc or other materials. This prevents corrosion.
