What does the designation "AL 3/ST1A" mean in the specifications?
The code designates the materials used in the conductor. "AL 3" refers to the high-strength aluminum alloy wires (Type AL3) which provide electrical conductivity, while "ST1A" refers to the galvanized steel core (Type ST1A, Class A coating) which provides the primary mechanical tensile strength.
Why are aluminum alloy steel reinforced conductors preferred for overhead power lines?
They combine the lightweight and excellent electrical conductivity of aluminum alloy with the high tensile strength of steel. This combination allows for longer span lengths, reduced sag, and high resistance to environmental loads like wind and ice.
How does the "Max. D.C. Resistance at 20℃" affect the power transmission?
D.C. resistance measures the conductor's opposition to electrical current. A lower resistance value (measured in Ohms/km) reduces electrical power losses (I²R losses) along the transmission line, thereby improving overall system efficiency.
What is the relationship between the linear mass and rated strength?
Linear mass (kg/km) represents the weight of the conductor per kilometer, while rated strength (kN) is the maximum tensile load it can withstand. Engineers use these values to calculate tower spacing, sag limits, and overall mechanical tension requirements for safe line installation.
Are these parameters compliant with international manufacturing standards?
Yes. The structure, material classes (AL3 and ST1A), and dimensional tolerances defined in this table are designed to comply with standard IEC, BS, or equivalent national standards for overhead electrical conductors.
