Overhead Lines

An overhead power line is intended for transmission of electric power through a bare or covered overhead conductor supported through insulators, commonly mounted on cross-arms near the top of poles. The overhead line may be 66, 33, 11 kV or LT line. The basic equipment used for the line remains the similar. The major equipment required for an overhead line is as follows:

1. supports,
2. cross-arms,
3. insulators,
4. earthing knob,
5. earthing coil,
6. strain hardware set,
7. conductors,
8. line accessories,
9. guard wires, and
10. LT line spacers.
