Product Description

ACAR (Aluminum Conductor Alloy Reinforced) - Application Standards & Construction

ACAR is an overhead power transmission conductor consisting of a high-strength aluminum alloy core surrounded by aluminum strands, combining high mechanical strength with good electrical conductivity. Below are its application standards and construction details.

 

1. Application Standards for ACAR

ACAR conductors must comply with the following international and industry standards:

(1) International Standards (IEC / ISO)

• IEC 61089 (Round wire concentric lay overhead electrical stranded conductors)

  • Defines material, construction, mechanical & electrical properties.

  • ACAR falls under "Case 2" (composite reinforced conductors).

• IEC 62004 (Thermal-resistant aluminum alloy wire for overhead line conductors)

  • Specifies requirements for heat-resistant aluminum alloy wires.

(2) American Standards (ASTM / IEEE)

• ASTM B399 (*Standard Specification for Aluminum-Alloy 6201 Wire for Electrical Purposes*)

  • Covers high-strength aluminum alloy wire (e.g., 6201-T81).

• ASTM B232 (Standard Specification for Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR))

  • Similar to ACSR, but ACAR uses an aluminum alloy core instead of steel.

• IEEE 738 (Standard for Calculating the Current-Temperature Relationship of Bare Overhead Conductors)

  • Used to determine ampacity and thermal behavior of ACAR.

(3) Chinese Standards (GB / DL)

• GB/T 1179-2017 (Concentric-lay-stranded overhead conductors)

  • Chinese equivalent of IEC 61089, covering ACAR specifications.

• DL/T 5092 (Technical code for designing overhead transmission lines)

  • Specifies ACAR application in power line design (span, sag, etc.).

 

2. Construction of ACAR

ACAR consists of a high-strength aluminum alloy core (AA-6201) and outer aluminum strands (1350-H19).

(1) Core Strands

• Material: AA-6201-T81 (high-strength Al alloy, tensile strength ≥305 MPa).

• Function: Provides mechanical support, reduces sag, and improves tensile strength.

• Structure: Single or multi-layer stranding (e.g., 7-wire, 19-wire).

(2) Outer Aluminum Strands

• Material: 1350-H19 (soft aluminum, conductivity ≥61% IACS).

• Function: Ensures electrical conductivity and reduces resistance losses.

• Stranding: Concentric lay (typically 1-2 layers).

3. Key Applications of ACAR

• HV/EHV Transmission Lines: Suitable for long spans and high mechanical load requirements.

• Coastal/Corrosive Environments: Aluminum alloy core offers better corrosion resistance than steel.

• High-Temperature Areas: Better heat resistance compared to standard ACSR.

 

4. ACAR vs. ACSR - Comparison

Feature	ACAR	ACSR
Core Material	Aluminum alloy (AA-6201)	Galvanized steel
Corrosion Resistance	Better (no steel rust)	Lower (steel vulnerable)
Weight	Lighter than ACSR	Heavier (steel core)
Conductivity	Slightly higher	Slightly lower
Mechanical Strength	High, but lower than ACSR	Very high (steel core)
