The 477 MCM Cosmos AAC conductor is a concentric-lay-stranded cable made of 19 aluminum alloy 1350 wires. It's built to ASTM B231 standards for bare overhead electrical conductors.
Key Features and Applications 💡
The 477 MCM Cosmos AAC conductor is ideal for low and medium voltage overhead lines, especially in urban and coastal areas. Its corrosion-resistant aluminum construction makes it a durable choice for harsh environments like marine settings, shipyards, and offshore sites. Its light weight also makes it an economical option, simplifying installation and reducing the need for heavy-duty fittings. This conductor can be used for most overhead transmission duties where conductor strength is not the main factor, as well as for primary and secondary distribution networks.
