ACSR
Aluminum conductors reinforced with galvanized steel core
Structure
Aluminum conductors reinforced with steel are a combination of 1350-H19 aluminum wires that are woven in one or more layers around a steel core in the center with a round cross-section. The direction of the texture of the outermost layer is right-handed and the lower layers respectively have the direction of the opposite texture.
Alumtek
Steel core is made of high carbon and high strength steel wires and galvanized coating is used to protect against corrosion.
A steel core can contain one or more threads (7, 19, 37 threads).
Alumtek
Galvanized coating is classified into different classes A, B, C according to the thickness of the coating, so that the lowest thickness corresponds to class A and the highest thickness corresponds to class C, increasing the thickness of galvanized coating leads to an increase in corrosion resistance in wires. The greater the coating thickness, the lower the mechanical strength, so class A has the highest mechanical strength and class C has the lowest strength. Therefore, if it is necessary to use ACSR conductors in highly corrosive environments, class B or C galvanized wires or steel with aluminum coating are used.

In ACSR conductors, it is possible to design a wide variety of layers and aluminum and steel wires. These conductors are mainly designed as structures of 1/6, 1/7, 12/7, 1/36, 24/7, 26/7, 30/7, 30/19, 54/7 and 19/54.
