ACSR (Aluminium Conductor Steel Reinforced)
Aluminum Conductor Steel Reinforced ACSR overhead cable
ACSR conductor consists of a solid or stranded steel core surrounded by strands of aluminium
Applications
ACSR conductors have been widely used in power transmission lines with various voltage levels, because they have such good characteristics as simple structure, convenient installation and maintenance, low cost large transmission capacity. And they are also suitable for laying across rivers valleys and the places where special geographical features exist.
Standard
IEC61089, ASTM B 232, DIN48204, BS 215 Part 2
Construction
The structure of ACSR is simple, it consists of a solid or stranded steel core surrounded by strands of aluminium.Aluminum 1350-H-19 wires, concentrically stranded about a steel core. Core wire for ACSR is available with class A, B, or C galvanizing; ""aluminized"" aluminum coated (AZ); Or aluminum-clad (AW). Additional corrosion protection is available through the application of grease to the corer or infusion of the complete cable with grease.
Specification
ACSR bare conductor meets or exceeds the following ASTM specifications:
B-230 Aluminum Wire, 1350-H19 for Electrical Purposes;
B-231 Aluminum Conductors, Concentric-Lay-Stranded;
B-232 Aluminum Conductors, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR);
B-341 Aluminum-clad Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AW);
B-498 Zinc-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ);
B-500 Zinc Coated and Aluminum Coated Stranded Steel Core for Aluminum Conductors, Steel Reinforced (ACSR);
