AAAC AL7 Conductor – All Aluminium Alloy Conductor

Product Overview

AAAC AL7 (All Aluminium Alloy Conductor) is an alloyed aluminium conductor manufactured in accordance with EN 50182. It is designed to provide a favorable strength-to-weight ratio while maintaining good electrical performance.

Compared with conventional FeAl conductors, AAAC AL7 offers excellent corrosion resistance and favorable tensioning characteristics, making it suitable for overhead power networks exposed to demanding environmental conditions.

With its combination of mechanical strength, electrical performance, and corrosion resistance, AAAC AL7 is widely used in power distribution and medium- to high-voltage transmission networks. Optional grease filling during the stranding process can provide additional protection against corrosion and help extend the conductor’s service life.

Conductor Construction

AAAC AL7 consists of stranded aluminium alloy wires concentrically laid to form an overhead conductor.

• Conductor Material: Aluminium alloy (AL7)
• Construction: Concentric-lay stranded wires
• Conductor Type: All Aluminium Alloy Conductor (AAAC)
• Surface Treatment: Optional grease filling during stranding

The conductor configuration, number of wires, and nominal cross-sectional area can be customized according to applicable standards and project requirements.

Applications

AAAC AL7 conductors are suitable for overhead power networks requiring a combination of mechanical strength, electrical performance, and corrosion resistance.

Typical applications include:

• Power Distribution Networks: Overhead distribution lines in utility networks.
• Medium-Voltage Transmission: Overhead conductors for medium-voltage power systems.
• High-Voltage Transmission: Applications requiring favorable strength-to-weight characteristics.
• Corrosive Environments: Power networks exposed to demanding environmental conditions.
• Utility Infrastructure: Overhead line construction and network expansion projects.

Key Features & Benefits

• High Strength-to-Weight Ratio: Provides favorable mechanical performance relative to conductor weight.
• Good Electrical Performance: Maintains suitable electrical characteristics for overhead power networks.
• Excellent Corrosion Resistance: Offers improved corrosion resistance compared with conventional FeAl conductors.
• Favorable Tensioning Characteristics: Suitable for overhead line installations requiring mechanical tension.
