Technical 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
Q1
What standard should be referenced for calculating other ACSR conductor structure parameters?
Except for the specific elastic and expansion coefficients applicable to France listed in the table, the calculation of all other ACSR conductor structure parameters should refer to the IEC61597 standard.
Q2
Under what environmental conditions are the table's flow rate values valid?
The flow rate values are applicable under a frequency of 60Hz, a wind speed of 0.6m/s, standard sunlight exposure in France, an ambient temperature of 35℃, and a maximum conductor temperature of 80℃.
Q3
How should flow rate values be adjusted if there is no air convection?
If the ACSR conductors are laid in special conditions where there is no convection, the flow rate values should be reduced by less than 30% to ensure safe operation.
Q4
What does the "direction of outside layer" (S or Z) mean?
The direction of the outside layer indicates the helical winding direction of the outermost aluminum wires. "S" stands for left-hand lay, and "Z" stands for right-hand lay, which is critical for choosing matching installation fittings.
Q5
Why does the table specify separate sectional areas for Aluminum and Steel?
ACSR combines the high conductivity of aluminum with the high tensile strength of galvanized steel. Listing individual sectional areas helps engineers calculate both the electrical resistance and mechanical load capacity of the composite conductor.
