Ja, the ground wires and rod ensure electrical safety and avoid electrical overloads, short circuits, lightning, usw. If the street lamp does not have a grounding electrode, when the street lamp equipment fails, the current will not find a flow path. They may flow through the human body, which will lead to accidental electric shocks.

The current can flow back to the earth through the ground electrode, thereby ensuring electrical safety.
