AAC(All aluminum conductor) are suited for overhead power line.

We can supply this conductor according to different recognized standards, such as IEC61089, BS215, BS EN 50182: 2001, ASTM B231, CSA C49, DIN480201, JIS C3109, customer special specification also can be satisfied.

ACSR or ACSR cable or ACSR conductor used for Overhead electrical distribution and transmission lines for distributing power.

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 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 corrosion or infusion of the complete cable with grease.

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 sun, 0.5 coefficients of emissivity and absorption.
