ACSR Conductors

Short note about ACSR Conductor.

• Its Full form is Aluminium conductor steel reinforced.
• It has central core of  Galvanized steel core with one or more layers of aluminum wires stranded outside.
• Reinforcement is done to increase the tensile strength of aluminum conductor.
• Steel wire is galvanized to prevent rusting and electrolytic corrosion.
• The ultimate tensile strength of such conductor is considerably larger than that of equivalent copper conductors and its weight is still about 25% lesser.
• Conductor gives less sag because of its less weight and high tensile strength.
• ACSR conductor has larger diameter than any other conductor of same resistance which helps to reduce corona.
• It is used for transmission lines where the span is more than 100 meters.

Advantages of ACSR Conductors

• High mechanical strength due to central steel wire.
• Long spans are possible.
• Reduces the number poles and other equipment’s.
• No corona effect.
• Longer life is possible.
• Cost is less.
• Used for overhead transmission lines.
