Aluminum stranded wire with steel core
Aluminum stranded wire with steel core (ACSR) is an electric power transmission conductor, which is a reinforced wire with single or multiple layers of aluminum strands stranded outside a galvanized steel core. It is mainly used in the electric power and transmission line industry. It consists of an aluminum strand and a steel core. The aluminum stranded part is used to transmit electrical energy, while the steel core is used to increase the mechanical strength and tension resistance of the wire to enable it to withstand stresses in complex environments such as long spans and strong wind loads.
The main features of ACSR conductors are good electrical conductivity, mechanical strength and tension resistance. The excellent electrical conductivity of the aluminum strand can ensure the efficiency and quality of the wire’s power transmission, while the excellent mechanical strength and tension resistance of the steel core can ensure the safe and reliable operation of the wire in complex environments such as strong wind loads.
Steel-core aluminum stranded wire has a simple structure, easy to set up and maintain, low line cost, large transmission capacity, and facilitate the laying of special geographic conditions such as across rivers and valleys, with good electrical conductivity and sufficient mechanical strength, tensile strength, tower distance can be enlarged and other characteristics. Therefore, it is widely used in various voltage levels of overhead transmission and distribution lines.
ACSR conductors are widely used in transmission lines, substations, power towers and other fields. In actual application, it is necessary to select the appropriate type, specification and brand of conductor according to different use occasions and requirements, and pay attention to the installation and maintenance of the conductor to ensure its stable and reliable operation.
