Detailed Solution
Download Solution PDFOverhead conductor of a transmission line
- Stranded conductors are used in overhead transmission lines rather than Solid Conductors.
- The reason is that stranded conductors offer more flexibility than solid conductors.
- The flexibility of stranded conductors is a good property that makes them easier to install and have a longer life as compared to solid conductors. Also, the stranded conductors are capable to withstand more vibration and bending before breaking.
- The most common conductor in use for transmission today is aluminum conductor steel reinforced (ACSR).
Properties of overhead conductor of a transmission line
An ideal conductor must have the following features:
- High electrical conductivity
- High tensile strength to withstand mechanical stresses
- Relatively lower cost without compromising much of other properties
- It should possess low specific gravity so that the weight per unit volume is small.
