Insulators prevent electrical current from flowing to the ground through the supporting structures.

Conductor material should efficiently carry electricity and withstand mechanical stress.

Cross arms provide a structure to hold insulators away from the pole, ensuring proper clearance.

Phase plates indicate which phase each conductor belongs to.

Insulators in overhead lines are used to support and separate the conductors, preventing electrical shock and short circuits.

The conductor material used for transmission and distribution of electric power should have high conductivity and low resistance to minimize energy loss.
The conductor material used for transmission and distribution of electric power should NOT have high reactivity or corrode easily to ensure long-term reliability.

Cross arms in overhead lines are used to support and maintain the spacing of the conductors, providing mechanical strength and stability to the transmission line.
Phase plates in overhead lines are used to identify the phase of the conductor, ensuring correct connections and avoiding phase mismatches.
