TRANSMISSION AND DISTRIBUTION - Practice Mode
1) What is the name of conductor used on overhead lines?
Correct Answer: ACSR
Explanation:
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.
2) What is the main purpose of crossarm used in electric poles?
Correct Answer: Holding the insulators on overhead line
3) Which type of line insulator is used at the dead ends of the H.T overhead lines?
Correct Answer: Disc insulator
4) What is the advantage of AC power transmission?
Correct Answer: Voltages can be stepped up and stepped down easily
5) What is ACSR stands for?
