Carrollton, GA, United States, 2007/12/07 - Southwire has released the 2nd Edition of the Overhead Conductor Manual, a design reference that consolidates basic information needed to evaluate the design, construction, uprating, and upgrading of overhead transmission and distribution systems.
Southwire Company has revised and released the Second Edition of their well-known Overhead Conductor Manual. "The Overhead Conductor Manual is a design reference that consolidates basic information needed to evaluate the design, construction, uprating, and upgrading of overhead transmission and distribution systems," says Ridley Thrash, Southwire chief engineer for overhead conductors.
Initially conceived as a reference for clients and a repository of Southwire engineering expertise, the Overhead Conductor Manual represents Southwire’s commitment of thousands of engineering hours and has grown into a valuable industry resource. First released in 1994, the new edition consolidates the most useful Overhead Conductor data and reflects latest industry practices and changes in the 2002 and 2007 National Electrical Safety Code.
Relevant new information & a bonus software tool
The Second Edition features new material on steel-supported conductors including High-Temperature, Low-Sag (HTLS) designs and updated information on ice and wind loading consistent with the National Electrical Safety Code. A special bonus, not available with the original Overhead Conductor Manual, is SWRATE™ Conductor Thermal Rating software, a program that calculates ampacity in accordance with current IEEE standards.
A useful educational tool for new engineers
"Our Manual is not a substitute for good engineering practices but can serve as an excellent educational resource for new engineers,” says Thrash. "It has proven to be a useful tool when used in conjunction with local, state and federal codes and design standards—some of which may supersede recommendations in the manual."
Fundamentals included in this addition that are familiar to those who use the Manual as a reference and educational tool include:
1) Basic overhead conductor concepts, including overviews of electrical and mechanical characteristics, and basic installation considerations
2) Design of new transmission lines, including in-depth sag and tension concepts and calculations
3) Thermal ratings of overhead conductors in steady-state and transient conditions, including the latest IEEE calculation methods
4) Mechanical effects of operating temperatures
5) Environmental effects, including radio noise, audible noise, and electrical and magnetic fields
6) Voltage upgrading and Thermal uprating of existing lines, including ACSS examples
Engineers and designers can purchase a copy of the Overhead Conductor Manual by visiting Southwire online. Single copies of the manual are available free of charge to select members of the Engineering trade press by contacting Kayla Smith at 770-832-4279.
