Aluminium Conductor Steel Reinforced (ACSR)

详情

Applications
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.

Construction
Aluminum alloy ****-H**9 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) - please see our ACSR/AW spec for more information. Additional corrosion protection is available through the application of grease to the corer or infusion of the complete cable with grease.

Specifications
ACSR bare conductor meets or exceeds the following ASTM specifications:

B***0 Aluminum Wire, ****-H*9 for Electrical Purposes
B***1 Aluminum Conductors, Concentric-Lay-Stranded
B***2 Aluminum Conductors, Concentric-Lay-Stranded, Coated Steel Reinforced (ACSR)
B***1 Aluminum-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ)
B***2 Aluminum-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AW)
B***8 Zinc-Coated Steel Core Wire for Aluminum Conductors, Steel Reinforced (ACSR/AZ)
B***0 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 *1.2% IACS for EC (***0) and 8% IACS for steel. AC (*0Hz) resistance includes current dependent hysteresis loss factor for 1 and 3 layer constructions.
Current ratings are based on *5oC conductor temperature, *5oC ambient, 2ft/s wind, *6/watts/sq.ft sun, 0.5 coefficients of emissivity and absorption.
