Printing and plotting of the Galloping Ellipses and Sag Curves is now done from within SAG10 or by switching
between applications to another graphics program of choice, rather than exiting to SagPlot. This is supplemented
by the DXF file option.
For individual data entry boxes, the TAB key is used to move from entry box to entry box, rather than the ENTER
key used previously. Each box is entered in the type over mode as a highlighted cell. If an ARROW, HOME or
END key are pressed, the entry box switches to the edit mode.
For data tables, standard spreadsheet table commands are used. The TAB, ENTER, or ARROW keys are used to
move from cell to cell. Each cell is entered in the type over mode. The F2 key will highlight the cell and initiate
editing of the cell. A row is inserted with Insert, a row is deleted with Delete. The Table is cleared with Clear.
Selecting a conductor is now an interactive process, where a conductor may be selected and reviewed as many
times as the user wishes prior to leaving the conductor selection area. After picking the Conductor Selection
(Main Menu) command, enter the conductor type, and codeword or other required data such as size and
stranding. Pressing the Lookup Wire Data command will search the database for the required data and display it
on the form. The Lookup Wire Data command will then become disabled until a modification is made in the
conductor request. If Main Menu or OK is picked and the requested entry data has been modified, the program
will lookup the new request prior to exiting the form.
The data output is displayed in a sizable window with scrolling capabilities. If Run - Pause between Spans (Main
Menu) is checked, the spans will display one at a time, to allow for reviewing Galloping, Sag Curves, Stringing Sag
Tables, and/or Clipping Offsets. If Run - Pause between Spans (Main Menu) is unchecked, all of the requested
spans will calculate and display in the sizable window at one time.

Chapter 1 Introduction
1.6 History
The Alcoa Graphic Method of sag-tension calculations was developed in 1926 by H. H. Rodee. Analysis of the
stress-strain behavior of the complete conductor and its component parts form the basis for the method. It is
applicable for composite conductors (ACSR's, OPGW's) or those consisting of one metal - aluminum, copper, or
steel. SAG10 is an enhancement of the mainframe Alcoa SAGTEN program available since 1963. The
enhancements include conductor data bases, for accurate and up-to-date data retrieval of most cataloged
conductors and overhead ground wires; elevated temperature creep, an important consideration today when
electrical demand taxes old designs; inclined span calculations, at times a perplexing mathematical problem;
offset clipping, a solution to a stringing problem; and use of screen editing and keyboard functions inherent to the
IBM-PC. In 1992, SAG10 Version 5 and SAGPLOT Version 1 were released. In 1994, SAG10 for Windows was
released. In 1997, Windows was updated with Version 1.1. In 1998, Windows was updated with Version 2.0. In
2001, Windows was updated with Version 3.0. The new features are listed on page 1 of this manual.

10. Continue on to "Getting Started with SAG10" below.
1.8.3 Installing and Using SAG10 On a Network
On a network, many users can share the SAG10 program and data files. Once SAG10 is set up on the network,
the program can be run from the network server, or it can be installed onto the hard disks of individual
workstations. This document assumes that you know how to use network software to connect to network drives
and how to find files stored on network computers.
Note: Every SAG10 user must either have a SAG10 Single User License, or the user's company must have a
LAN/Client Server license or a Site License.
Before you set up SAG10
The network must be operational, and you must have read-write access to the network directory in which you want
to install SAG10. For more information, see your network software documentation.
Setting up SAG10 on a network is a two-step process. You first install SAG10 on the network server. Then you set
up the workstations, either by setting up the workstations to run SAG10 from the server or by installing SAG10 on
each workstation's hard disk. Note: Each workstation should have at least 16 MB of RAM in order to run the
SAG10 program.
1.8.4 Installation of SAG10 on a Network Server
1. Follow steps 1 thru 5 for 1.8.2 Installation - Single User, with the exception that the drive is likely to some letter
higher than C:, such as R:\Sag10Net3\.
Although the SAG10 program directory on the server (the directory containing Sag10w3.EXE) can be either read-
write or read-only, you should make it read-only after installing SAG10 to prevent users from unintentionally
overwriting files. For more information, see your operating system documentation.
