AAC (All-Aluminum Conductor) is a type of electrical conductor made entirely of aluminum wires. It is mainly used in urban areas with short distances and close supports, used in overhead electric power transmission and distribution lines with various grade voltages. It mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.Its characteristics are good corrosion resistance, and it can also be used near the coast.

It mainly used as bare overhead transmission cable and as primary and secondary distribution cable. It is also suitable for laying across basins, rivers and valleys where special geographical teatures exist.Its characteristics are good corrosion resistance, and it can also be used near the coast. Some common applications of AAC conductors include:
Although less commonly used in high-voltage transmission lines compared to other conductors like ACSR, AAC conductors are still used in some applications where high conductivity and low weight are important considerations.
AAC are frequently used in medium-voltage distribution lines to transmit electricity from substations to homes and businesses.
All aluminum conductors are a popular choice for power transmission and distribution systems in rural and remote areas due to their lightweight and ease of installation.
The corrosion resistance of aluminum makes all aluminum conductors suitable for use in coastal areas where there is a risk of corrosion from saltwater and high humidity.
All aluminum conductors are also used in urban areas where the lightweight construction allows for easier installation on poles and towers in areas where space is limited.
The structure of an AAC (All-Aluminum Conductor) hard drawn aluminum conductor as per EN 60889 Type AL1 according to BS 215. And consists of multiple concentric layers of aluminum strands. The outermost layer comprises the largest diameter strands, and the innermost layer consists of the smallest diameter strands.
The wires in each layer are helically twisted together in a direction opposite to the direction of twist of the adjacent layer. This counter-twisting helps to prevent the conductor from unraveling and provides the conductor with strength and flexibility.
The overall structure of an AAC conductor can vary depending on the application and the desired properties of the conductor. For example, some AAC conductors are designed with a central wire for added strength, while others are designed with a compact stranding pattern for increased conductivity and reduced wind resistance.
All aluminum conductors meets or exceeds the following standards: IEC61089, BS215 part1, DIN48201 part5, ASTM B231, BS EN50182, Chinese Standard GB/T1179-2008, We can also manufacture AAC according to customer's special requirements.
All Aluminum Conductor is in Accordance with BS215-1-70
