Sag Calculation
The primtech sag calculation tool calculates the temperature dependent forces – sag table for flexible conductor and conductor bundles. It also outputs an installation table.
The sag calculation supports the comparison of several scenarios and gives you the results in a report.
Additional Loads
Additional points of interest, e.g. above streets, can be set freely (as table columns). Strings and connected conductors are detected as additional loads and only need to be specified. Additional loads e.g. weights or pantograph contacts can be set freely along the bundles.
Weather Conditions
Mass dependent, temperature dependent forces and additional loads – caused by the weather e.g. wind, ice as well as wind on ice – can be taken into consideration in the sag calculation. The weather conditions can be set quickly and easily for both the whole substation and parts of the substation. Since all available values are read directly from the primtech information model and the conductor connections are grouped automatically, the need for you to input parameters is reduced to a minimum.
Sag Table
This table contains the calculated temperature dependent sag values for the desired points on the wire and loads as well as the respective occurring conductor tensile forces. The table further displays horizontal and vertical forces on the anchor points.
Installation Table
The installation table, which is needed for the installation of the conductor, is also created by primtech. In the installation table, additional loads are not taken into consideration so that the installer can read the respective sag or tensile forces depending on the temperature.
Excel Output
The results and tables are displayed quickly and clearly after each calculation. You can then output the results to an Excel table.
Scenario Calculations
primtech supports the comparison of several scenarios, e.g. for different conductor specifications, in order to optimize the design of the substation. This can be done by just copying an already defined scenario and adjusting the relevant values so as to compare the calculation results.
30+ years of industry experience
What does the primtech sag calculation calculate?
It calculates the temperature dependent forces and sag tables for flexible conductors and conductor bundles, and it also outputs an installation table.
Which weather conditions can be considered?
Mass dependent and temperature dependent forces as well as additional loads caused by the weather – e.g. wind, ice and wind on ice – can be taken into consideration, for the whole substation or for parts of it.
Do I have to enter all parameters manually?
No. All available values are read directly from the primtech information model and the conductor connections are grouped automatically, so the need to input parameters is reduced to a minimum.
What is the difference between the sag table and the installation table?
The sag table contains the temperature dependent sag values and conductor tensile forces including additional loads. The installation table does not take additional loads into consideration, so the installer can read the respective sag or tensile forces depending on the temperature.
Can I compare different design variants?
Yes. primtech supports the comparison of several scenarios, e.g. for different conductor specifications. Simply copy an already defined scenario and adjust the relevant values. The results can be output to an Excel table.
