Textbook Question
Chapter 4, Problem 4.1MCQ
ACSR stands for
- Aluminum-clad steel conductor
- Aluminum conductor steel supported
- Aluminum conductor steel reinforced
Expert Solution & Answer
To determine
The full-form of ACSR.
Answer to Problem 4.1MCQ
The correct option is (c), aluminium conductor steel reinforced.
Explanation of Solution
The ACSR stands for aluminium conductor steel-reinforced. It is one of the most common conductor types which consists of aluminium strands layer that surrounds a central core of steel strand. Steel strands used in ACSR conductors gives a high strength-to-weight ratio. The outer aluminium strands have good conductivity, low weight and low cost. ACSR is mainly used in overhead power lines because of its high-capacity and high strength.
So, the correct option is (c).
