Specifications
ASCR/TW is Aluminum Conductor Steel Reinforced Trapezoidal Shaped Aluminum Strands
ACSR/TW
 
APPLICATIONS
 
Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductor, Steel-Reinforced(ACSR/TW) is designed for use as a bare overhead conductor. There are two designs of ACSR/TW. One design gives an equal area of aluminum when compared to the standard ACSR conductor sizes. The other design gives an overall outside diameter equal to standard ACSR conductor sizes. Use of this conductor in the equal area design allows equal ampacity in a smaller diameter conductor when compared with standard ACSR conductor. Use of this conductor in the equal diameter design allows more ampacity in an equal diameter conductor when compared with standard ACSR conductor.
 
SPECIFICATIONS
 
Tong-Da ACSR/TW conductor meets or exceeds ASTM specification:
 
•  B-779  Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Steel-Reinforced (ACSR/TW).
 
CONSTRUCTION
 
Aluminum alloy 1350-H19 trapezoidal shaped wires, concentrically stranded about a steel core. Core wire for ACSR/TW is available with class A, B, or C galvanizing; "aluminized" aluminum coated (AZ); or aluminum-clad (AW1).  Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
 
NOTES
+ Ampacity calculated assuming: ambient 250C, conductor 75 ºC, wind 2 ft./ sec., sun.
