Q1. Are the statements True or false? correct the wrong statement! 1. The overhead Transmission line is rarely used for power transmission due to the installation costs compared with the underground cables. 2. The aluminum conductor has almost one-half the weight of the equivalent copper conductor because aluminum's specific gravity is more than for the copper. 3. Creosote oil is the most commonly used material for insulators of the overhead line. 4. The discharge occurs between the insulator and the bin through the conductor's body, called a puncture. 5. The low cost of Pin insulators enables it to be a good alternative for the suspension insulators when the line voltage exceeds 33kV.
