AAC Conductor, All Aluminium Conductor (ASTM B 231)
AAC conductor is widely used in power transmission lines with various voltage levels.
Since they have such good characteristics as simple structure, convenient installation and maintenance, low cost for the line, large transmission capacity and are also suitable for laying across rivers and valleys where special geographical teatures exist.

1. Specification:
All aluminium conductor (AAC)

2. Relative manufacturing standards:
ASTM B 231: Stranded Specification for Concentric-Lay-Stranded Aluminium 1350 Conductors

3. Construction:
Aluminum alloy 1350-H-19 wires. 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 75℃ conductor temperature, 25 ℃ ambient, 2ft/s wind, 96/watts/sq. Ft sun, 0.5 coefficients of emissivity and absorption.
