680/85 Bare ACSR Conductor
- 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
- Additional corrosion protection is available through the
application of grease to the corer or infusion of the complete
cable with grease.
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.
ACSR bare conductor meets or exceeds the following ASTM
- 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]).
- 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
