Frequently Asked Questions (FAQ)
Q
What is ACSR (Aluminum Conductor Steel Reinforced)?
ACSR is a high-capacity, high-strength stranded conductor typically used for overhead power transmission and distribution lines. It consists of a solid or stranded steel core surrounded by outer layers of high-purity aluminum strands, combining the lightweight and high conductivity of aluminum with the mechanical strength of steel.
Q
What do the fruit code names (like Almond, Cherry, Walnut) mean?
These code names are standard industry identifiers (often defined by British Standards or other regional bodies) used to simplify ordering and referencing. Each code name corresponds to a unique combination of sectional area, wire stranding, diameter, and mechanical properties.
Q
Why is the outermost layer of the ACSR conductor twisted to the right (Z)?
A right-hand lay (Z-lay) is the standard outermost layer configuration for ACSR conductors. This specific twisting direction ensures compatibility with standard installation tensioning equipment, line fittings, and accessories, while providing structural integrity under environmental loads.
Q
How does the steel core affect the performance of ACSR?
The galvanized steel core significantly increases the nominal breaking load (tensile strength) of the conductor. This allows for longer spans between transmission towers with reduced sag, making it ideal for crossing rivers, valleys, and challenging terrains.
Q
What is the relationship between ACSR conductor size and electrical resistance?
As the total sectional area of the aluminum increases (e.g., from 29.5 mm² for Almond to 519.5 mm² for Olive), the maximum electrical resistance at 20℃ decreases (from 0.975 Ω/km down to 0.0557 Ω/km). Lower resistance reduces transmission power losses and increases the overall current-carrying capacity.
