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 twisting direction for the outermost layer of AAAC?
The outermost layer of the Aluminum Alloy Conductor (AAAC) is twisted to the right (Z-lay).
Which standard should be used for other AAAC conductor structure calculations?
For calculating other conductor structure parameters not specified in this table, you should refer to the IEC61597 standard.
Under what conditions are the listed current-carrying capacities valid?
The current-carrying capacities (flow rate values) are calculated based on 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℃.
How should the flow rate values be adjusted if there is no convection?
If there are special laying conditions without convection, the current-carrying capacity (flow rate) values should be reduced by at least 30%.
Where do the listed elastic and linear expansion coefficients apply?
The elastic coefficients and linear expansion coefficients listed in this specification table are specifically applicable to Germany.
What is the range of sectional areas covered in this specification table?
The nominal sectional areas for the listed AAAC conductors range from 15.9 mm² (for code 16-AL3) up to 999.7 mm² (for code 1000-AL3).
