AACSR — Aluminum Alloy Conductor Steel Reinforced

AACSR / AACSR-AW Conductor

Aluminium Alloy Conductor Steel Reinforced

Product Overview

AACSR conductor manufacturer in China. AACSR (Aluminium Alloy Conductor Steel Reinforced) is a high-strength bare overhead conductor designed for power transmission and distribution lines requiring excellent mechanical strength and reliable electrical performance.

It consists of concentric layers of high-strength aluminum alloy wires stranded around a reinforced steel core. The aluminum alloy strands, typically made from 6201-T81, provide electrical conductivity and mechanical strength, while the steel core delivers additional tensile strength for demanding overhead line conditions.

Compared with conventional ACSR conductors, AACSR uses high-strength aluminum alloy wires instead of standard electrical-grade aluminum wires. This construction provides a favorable strength-to-weight ratio and makes AACSR suitable for long-span transmission lines, river crossings, mountainous terrain and other applications requiring increased mechanical strength.

QZ Cable manufactures AACSR conductors in different sizes, stranding configurations and steel core options to meet international standards and project specifications.

Construction of AACSR Conductor

AACSR is a concentric-lay stranded conductor consisting of one or more layers of aluminum alloy wires stranded around a high-strength coated steel core.

Aluminum Alloy Strands

The conductive and reinforcing layers are typically manufactured from high-strength Aluminum Alloy 6201-T81 wires. Alloy 1120 may also be considered for specific designs where supported by the applicable material and conductor specifications.

Steel Reinforcing Core

The central core consists of one or more high-strength coated steel wires. The steel core provides the mechanical reinforcement required for high tensile loads and long-span overhead applications.

Flexible Conductor Design

The proportions of aluminum alloy and steel can be adjusted to achieve the required balance between electrical capacity and mechanical strength.

The core can be supplied with different protective coatings, including:

• Class A galvanized steel.
• Class B galvanized steel.
• Class C galvanized steel.
• Aluminum-coated steel (AZ).
• Aluminum-clad steel (AW).

AACSR and AACSR/AW Conductor Types

1. AACSR – Aluminium Alloy Conductor Steel Reinforced

AACSR uses high-strength aluminum alloy strands surrounding a coated steel reinforcing core.

Key characteristics:

• High mechanical strength.
• Favorable strength-to-weight ratio.
• Reliable electrical conductivity.
• Different steel core coating options.
• Suitable for long-span overhead transmission and distribution lines.

2. AACSR/AW – Aluminium Alloy Conductor Aluminum-Clad Steel Reinforced

AACSR/AW is a special AACSR construction using aluminum-clad steel wires as the reinforcing core instead of conventional galvanized steel wires.

The aluminum cladding provides improved corrosion resistance and a compatible aluminum surface in contact with aluminum alloy strands.

Key characteristics:

• Improved corrosion resistance compared with conventional galvanized steel core constructions.
• High mechanical strength.
• Aluminum-clad steel core construction.
• Suitable for coastal, industrial and other corrosive environments.
• Compatible with specific overhead conductor and OPGW designs.

Key Features and Advantages

High Mechanical Strength

The combination of high-strength aluminum alloy strands and a steel reinforcing core provides excellent tensile performance for overhead lines with demanding mechanical requirements.

Excellent Strength-to-Weight Ratio

AACSR combines lightweight aluminum alloy strands with a high-strength steel core, providing a favorable balance between conductor weight and mechanical strength.

Reliable Electrical Performance

The aluminum alloy strands provide electrical conductivity while contributing to the conductor’s overall mechanical strength. The conductor design can be customized according to the required current-carrying capacity.

Long-Span Capability

AACSR is suitable for long-span applications, including river crossings, valley crossings and mountainous transmission routes, where high tensile strength is important.

Flexible Corrosion Protection

Different steel core coatings can be selected according to environmental conditions. Additional grease protection can also be considered where required by the conductor specification.

Applications of AACSR Conductors

AACSR and AACSR/AW conductors are commonly used in:

• Overhead power transmission lines.
• Primary and secondary distribution networks.
• Long-span river and valley crossings.
• Mountainous and difficult-terrain transmission routes.
• High-wind regions requiring high mechanical strength.
• Coastal and industrial environments.
• Utility grid expansion and reinforcement.
• Overhead messenger and support applications where specified.
