Construction:
Aluminum alloy 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.
Application:
Used as bare overhead transmission cable and as primary and secondary
distribution cable. ACSR offers optimal strength for line design. Variable
steel core stranding enables desired strength to be achieved without
sacrificing ampacity.
Specifications:
ACSR bare conductor meets or exceeds the following ASTM specifications:
ASTM B-230 (Aluminum wire, 1350-H19 for electrical purposes).
ASTM B-231 (Aluminum conductors, Concentric-lay-stranded).
ASTM B-232 (Aluminum conductors, Concentric-lay-stranded, Coated steel
reinforced [ACSR]).
ASTM B-341 (Aluminum-coated steel core wire for aluminum conductors, Steel
reinforced [ACSR/AZ]).
ASTM B-498 (Zinc-coated steel core wire for aluminum conductors, steel
reinforced [ACSR/AZ]).
ASTM B-500 (Zinc-coated and aluminum coated stranded steel core for aluminum
conductors, steel reinforced [ACSR]).
Notes:
Resistance is calculated using ASTM standard increments of stranding and metal
conductivity of 61.2% IACS for EC (1350) and 8% IACS for steel. AC (60Hz)
resistance includes current dependent hysteresis loss factor for 1 and 3 layer
constructions.
Current ratings are based on 75oC conductor temperature, 25oC ambient, 2ft/s
wind, 96/watts/sq.ft
