AAC (All Aluminum Conductor) to CSA C49 is a bare overhead conductor widely used in Canadian power transmission lines. It's a popular choice due to its simple construction, ease of installation, and low cost. The conductor is suitable for a wide range of applications, including installations across rivers and valleys.
Key Specifications
- Standard: CSA C49, which covers stranded aluminum conductors for Canadian sizes.
- Conductor Material: Consists of concentric-lay-stranded hard-drawn 1350-H19 aluminum wires with a minimum purity of 99.55%.
- Construction: The wires are helically wrapped around a central core, with each successive layer having six more wires than the one beneath it.
- Insulation: None; this is a bare conductor.
- Nominal Area: The conductor is available in a wide range of sizes, from 6 AWG to 3500 MCM.
- Temperature Rating: Designed for continuous use at temperatures up to C.
Application Classes
The conductor's flexibility is defined by its class:
- Class AA: Used for bare overhead lines, this is the least flexible class.
- Class A: Used for conductors with weather-resistant coverings or where greater flexibility is needed.
- Compact Strand: An option for bare overhead applications or with weather-resistant coverings, offering increased flexibility.
