READING A SAG TENSION TEMPERATURE CHART

ExampleConductor MOON (7/4.75 AAC)Stringing Tension: Table 220Span Length: 74mMES of Strain Section: 108m

Temperature: 50°C

(a) Determine the sag and the tension in the conductorunder the above (no wind) condiitions.

(b) Determine the conductor tension at 15°C under windconditions.

Answer

Solution

1. Select the Sag-Tension-Temperature chart for AAC conductorat stringing table T220, as shown below.

2. Plot the MES length of 108m on the horizontal axis – Point A.Always ‘enter’ the chart from the MES.

3. Trace upwards vertically to the 50°C curve – Point B.

4. Now we have established the tension in the line, which we canread by tracing a horizontal line across to the tension scale forMOON at the left – Point C. Reading from the chart, thetension in the conductor is 1.53kN.

5. To determine the sag, we now plot the actual span length of74m on the horizontal axis – Point D.

6. Trace upward to the horizontal line showing tension, at PointE. Looking at the sag contours on the chart, we note that thesag is slightly less than 1.5m – 1.49m say.

7. For wind conditions, consult the Sag-Tension Chart for AACT440 – T110 under wind conditions, as shown below. This is asimpler type of graph to read.

8. Plot the actual span length of 74m on the horizontal axis.

9. Trace upward to the curve for MOON at T220.

10. Trace across to the y-axis, and read the tension from thescale, viz. 3.8kN.
