What is the minimum permissible size of ACSR conductor?
As per Indian Electricity (IE) rules, The minimum permissible size of wire for the lighting circuit is 1 sq. mm for copper cable. The minimum permissible size of wire for the lighting circuit is 1.5 sq.
Why ACSR conductor is preferred for transmission?
The favorable strength/weight ratio, achieved by the lightweight, strong conductivity of aluminium coupled with the high tensile strength of steel, makes ACSR conductors a preferred choice for overhead power transmission and distribution projects.
How do you find the ampacity of a conductor?
Ampacity can be calculated by dividing the Wattage by the rated voltage. The quotient is the expected Amperage of the circuit. In many instances, a circuit’s unique application correction factors (as described above) will warrant the need for ampacity adjustments.
How do you calculate the current carrying capacity of an ACSR conductor?
- At 132 kv. Power in MW = Ö 3 132 x I x 0.8 / 1000. = 0.1828992 x I. = 0.183 x I.
- At 220 kv. Power in MW = Ö 3 220 x I x 0.8 / 1000. = 0.305 x I.
- At 400 kv. Power in MW = Ö 3 400 x I x 0.8 / 1000. = 0.554 x I.
What do you mean by ACSR conductor?
ACSR conductor or aluminum conductor steel reinforced is used as bare overhead transmission and as primary and secondary disribution cable. ACSR is suitable for use in all practical spans on wood poles, transmission towers, and other structures because of its dependability and strength to weight ratio.
What is meant by ACSR?
Aluminium conductor steel-reinforced cable (ACSR) is a type of high-capacity, high-strength stranded conductor typically used in overhead power lines. The outer strands are high-purity aluminium, chosen for its good conductivity, low weight, low cost, resistance to corrosion and decent mechanical stress resistance.
