HS285 overhead conductors are ultra-high strength ACSS conductors with a steel core that is up to 36% stronger than a standard ACSR core while being able to withstand up to 285 ksi. HS285 overhead conductors are able to be strung tighter with less sag, allowing for a 60-95% increase in available capacity over standard ACSR.
The manual was designed to better assist transmission line engineers and system planners in the selection of overhead conductors and to provide general guidance in transmission line design and/or uprating. The intent of the book is to consolidate the engineering reference data most used by line design engineers into a single source with guidance to finding additional, more in-depth information in related reference material. While the manual is not a substitute for good engineering practices, it does provide engineers with a comprehensive overview of the most up-to-date-technologies and best use cases.
