Alcan Cable manufactures a full line of ACSS cables which are used in overhead distribution and transmission lines. Alcan offers various conductor designs and steel core coatings to address your application requirements.
HiTemp EC™, Alcan's Aluminum Conductor Steel Supported cable, is a composite concentric lay-stranded conductor consisting of a stranded steel central core with one or more layers of 1350-0 aluminum wires. Steel core wires are protected from corrosion by aluminum-clad or zinc - 5% aluminum mischmetal alloy coating. Standard, High, Extra High and Ultra High strength steel are also available. All ACSS and ACSS/TW products are available in a non-specular finish.
Although similar to conventional ACSR cable, HITemp EC conductors provide distinct advantages for certain transmission line applications including:
Operates continuously at high temperatures up to 250° C with appropriate
steel core coating vs. 100° C for standard ACSR
Carries substantially more current than standard ACSR
Reduced sag allows for lower transmission tower height
