Application

HS285 is the most popular high temperature low sag (HTLS) conductor in use today because of its versatility and strength. The multipurpose conductor is up to 21 percent stronger than standard ACSS, reducing sag while allowing for additional line capacity. Developed at Southwire’s D.B. Cofer Technology Center, HS285 has been proven in the field for capacity up to 95 percent higher than ACSR, lowering reconductoring costs. HS285 can be strung tighter to operate with more clearance at higher temperatures. It also allows for easy installation using existing rights of way, structures and methods.

Construction

ACSS is a composite concentric-lay-stranded conductor. Steel strands form the central core of the conductor with one or more layers of 63% minimum average conductivity aluminum 1350-0 wire stranded around it. The steel core carries most or all of the mechanical load of the conductor due to the “0” (fully annealed or soft) temper aluminum. Ultra high-strength steel core wires are protected from corrosion by Galfan® , zinc-5% aluminum-mischmetal alloy coating.
