Note:
1. 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.
2. 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 is ACSR (Aluminum Conductor Steel Reinforced)?
ACSR is a high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminum, providing excellent conductivity, while the center core is galvanized steel for additional mechanical strength to support the cable over long spans.
What standards are used to calculate ACSR conductor parameters?
The parameters and calculations of the ACSR conductor structure generally refer to the international standard IEC61597, though specific elastic and expansion coefficients may vary based on regional requirements (such as those applicable to France).
Why is the direction of the outside layer (S or Z lay) important?
The direction of the outside layer (indicated as 'S' or 'Z') determines the winding direction of the outer strands. This direction is critical for structural stability, ensuring the conductor does not unravel during installation and matches standard jointing accessories.
How does ambient temperature affect the flow rate values of ACSR?
The standard flow rate values are calculated under specific benchmark conditions (e.g., 60Hz frequency, 0.6m/s wind speed, 35℃ ambient temperature, and 80℃ conductor temperature). Under special laying conditions without natural convection, the flow rate capacity should be reduced by up to 30%.
What is the purpose of the galvanized steel core in ACSR?
The galvanized steel core provides the necessary tensile strength to support long spans between transmission towers. Because aluminum has relatively low mechanical strength, the steel core carries most of the physical load, reducing sagging over time.
