APPLICATION

AAC (All Aluminum Conductor) is a stranded overhead conductor made entirely of hard-drawn aluminum wires without any steel core. It features high electrical conductivity, light weight, simple structure and excellent corrosion resistance. Due to its lower mechanical strength and larger thermal sag compared with ACSR, AAC has fixed and targeted application scenarios in power distribution and transmission systems.AAC conductor cables are mainly used in urban areas where the spacing is short and the support points are close together.

All aluminum conductors consist of one or more aluminum wires, depending on the end use. AAC is also widely used in coastal areas because it is highly resistant to corrosion. Concentric stranded aluminum conductor (AAC) is made of hard drawn aluminum wire (HDA conductor).

Construction

AAC is a concentric-lay-stranded conductor consisting of hard drawn aluminum wires. All aluminum conductors (AAC) are made up of one or more strands of aluminium wire depending on the end usage.

CHARACTERISTICS

Characteristics of All-Aluminum Stranded Conductors

1 Structural Characteristics

1.1 The conductor is concentrically stranded entirely with 1350-H19 hard-drawn aluminum wires, without any steel core, featuring a simple and single structure composed of multi-layer spiraled aluminum strands.

1.2 Light weight: It has a lower self-weight than ACSR with the same cross-sectional area, which reduces the load on supporting transmission towers.

1.3 Good flexibility: It is easy to bend, reel, transport and string during field installation with smaller delivery reels.

1.4 No contact between aluminum and dissimilar steel metals, eliminating the risk of bimetallic galvanic corrosion inside the cable.

2 Electrical Characteristics

2.1 Excellent conductivity with a conductivity of approximately 61% IACS. The whole conductor participates in power transmission without non-conductive steel core occupying conductive space.

2.2 Optimized utilization of skin effect with no extra power loss induced by steel core, delivering slightly higher ampacity than ACSR of equal cross-section.

2.3 Stable DC resistance and uniform temperature coefficient due to homogeneous aluminum material, simplifying resistance calculation for engineering design.

2.4 Larger outer diameter reduces corona loss and radio interference, making it suitable for medium and low voltage overhead lines.

2.5 Continuous allowable operating temperature ranges from 70℃ to 90℃. Hard-drawn aluminum will anneal and soften under long-term high temperature, so it is not applicable for sustained heavy-load high-temperature working conditions.

3 Mechanical Characteristics

3.1 Low tensile strength without steel reinforcement; its rated breaking force is much lower than ACSR with identical cross-section.

3.2 High linear thermal expansion coefficient (23×10⁻⁶/℃). The sag increases sharply when the conductor heats up under load, restricting its use for long span transmission sections.

3.3 Poor resistance to heavy ice coating and strong wind vibration; it is prone to excessive sag and strand breakage under harsh meteorological loads.

3.4 Limited span length: Only suitable for short tower distances in flat and mild-climate areas.

4 Environmental & Economic Characteristics

4.1 Superior corrosion resistance for corrosive environments such as coastal salt fog and industrial acid-alkali gas zones, as there is no steel core susceptible to rust.

4.2 Low raw material and construction cost, with simple production process and convenient maintenance.

4.3 Fully recyclable aluminum material, eco-friendly for power grid construction projects.

ACSR-Aluminum Conductor Steel Reinforced

Aluminium Conductor Steel Reinforced (ACSR) consists of a solid or stranded steel core in the centre, and concentrically stranded aluminum wires in external layers. Additional corrosion protection is available through the application of grease to the core or infusion of the complete cable with grease.
