AAC 630mm² (All Aluminum Conductor) is a concentric-lay stranded conductor made from electrically refined 1350-grade aluminum with a minimum purity of 99.7%. This type of conductor is widely used for overhead power transmission and distribution in urban areas, where high conductivity and corrosion resistance are required and span lengths are relatively short.
Thanks to its lightweight construction and excellent corrosion resistance, AAC 630mm² is particularly suitable for coastal regions and locations where copper alternatives may be less practical. It is also compatible with aluminum service connection systems, reducing the need for aluminum-to-copper transitions.
Applications
Overhead transmission and distribution lines (low, medium, and high voltage)
Ideal for urban installations with short spans
Common in coastal and corrosive environments
Service connections using aluminum-compatible terminations
Suitable for areas where high electrical conductivity is essential
AAC Conductor 630mm2 Construction
AAC 630mm² is composed of multiple strands of hard-drawn 1350 aluminum wire, helically stranded in a concentric-lay construction. The number and diameter of strands are designed according to international standards to achieve the required cross-sectional area and mechanical strength.
