Important Notes:
- The elastic coefficients and expansion coefficients listed in this table are applicable to France. The calculation of other conductor structure parameters shall refer to IEC61597.
- 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 France, 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 standard is used to calculate the ACSR conductor structure parameters?
Except for the elastic and expansion coefficients specific to France, the calculations for other conductor structure parameters of these ACSR conductors refer to the international standard IEC61597.
Under what conditions are the listed ACSR flow rate values applicable?
The flow rate values apply under specific standard conditions: a frequency of 60Hz, a wind speed of 0.6m/s, direct sunlight exposure in France, an ambient temperature of 35℃, and a maximum conductor temperature of 80℃.
How does a lack of wind convection affect the flow rate of ACSR conductors?
If there is no wind convection under actual laying conditions, the current carrying capacity (flow rate) of the ACSR conductor should be reduced by at least 30% to prevent overheating.
What do the "S" and "Z" symbols stand for in the direction of the outside layer?
"S" and "Z" represent the lay direction of the outermost layer of aluminum wires. "S" stands for left-hand lay direction, and "Z" stands for right-hand lay direction, which is critical for proper mechanical locking and performance.
What is the composition of the product structure in the ACSR specification?
The structure comprises two parts: the outer Aluminium Wire (with specified wire diameter in mm and number of strands) and the inner reinforcing Galvanized Steel Wire (also with specified wire diameter and number of strands).
