What is an ACSR Conductor?
Aluminum conductor steel-reinforced cable is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines.
The outer strands are high-purity aluminum, chosen for its good conductivity, low weight, low cost, resistance to corrosion, and decent mechanical stress resistance.
ACSR Conductor Suppliers In South Africa
ACSR. Unity Cables is a leading supplier of aluminum conductor electrical cables in Johannesburg, South Africa. Aluminum conductors have achieved wide acceptance all over the world for use in overhead transmission and distribution lines.
Why are ACSR conductors widely used?
ACSR (aluminum conductor steel reinforced) has a long service record because of its economy, dependability, and strength-to-weight ratio.
The combined light weight and high conductivity of aluminum with the strength of the steel core enables higher tensions, less sag, and longer spans than any alternative.
What are the advantages of an ACSR conductor over a copper conductor?
Advantages of ACSR conductors over copper conductors:
The conductivity of the ACSR is higher than the copper conductor. ACSR conductor can be used for medium and long spans and needs less support. The mechanical performance and Tensile strength of the ACSR conductor are High.
How do I choose an ACSR conductor?
- Short circuit withstand capacity of the conductor – This should be equal to or greater than the fault level of the transmission line.
- Nominal current rating of the conductor – This should be equal to or greater than the continuous current requirement of the transmission line.
- The voltage level of the transmission line.
What is the maximum operating temperature of ACSR?
The upper-temperature limit used in an ACSR conductor is at present 90 °C (continuous) to 120 °C. Even if the range of the current increase is 50%, the increase in the conductor temperature is limited to roughly 50% (140 to 180 °C) of the above figures.
What is the range of ACSR conductors?
ACSR conductor is available in a range of steel strengths varying from 6% up to 40%. The higher-strength ACSR conductors are used for river crossings, overhead earth wires, and installations involving extra-long spans.
