Note:
1. The outermost layer is twisted to the right (Z).
2. The elastic coefficients and expansion coefficients listed in this table are applicable to Germany. The calculation of other conductor structure parameters shall refer to IEC61597.
3. The flow rate values listed in this table are applicable under the conditions of a frequency of 60HZ, a wind speed of 0.6m/S, sunlight exposure in Germany, an ambient temperature of 35℃, and a conductor temperature of 80℃. In case of special laying conditions, the flow rate values should be reduced if there is no convection Less than 30%.
Frequently Asked Questions (FAQ)
What is the standard lay direction for the outermost layer of these AAAC conductors?
The outermost layer of the Aluminum Alloy Conductor (AAAC) is twisted to the right, which is designated as (Z) lay direction.
Which standard should be used to calculate other structural parameters for AAAC?
For calculating conductor structure parameters other than those listed in the table, reference should be made to the IEC61597 standard.
Under what environmental conditions is the listed current-carrying capacity calculated?
The current-carrying capacity (flow rate) is calculated based on a 60Hz frequency, 0.6m/s wind speed, sunlight exposure conditions in Germany, an ambient temperature of 35℃, and a maximum conductor temperature of 80℃.
How does the lack of convection affect the current-carrying capacity?
If there is no convection under special laying conditions, the flow rate (current-carrying capacity) values should be reduced by less than 30%.
Are the elastic and expansion coefficients in the table applicable globally?
No, the elastic coefficients and linear expansion coefficients listed in this specification table are specifically applicable to Germany.
