Not always. Some times the neutral wire will be isolated from ground by small insulators that will flash over in the event of a lightning strike, but typically it's been my experience that the neutral wire will be bare conductor, and grounded multiple times through structure grounds on high voltage transmission lines.

Can you run insulated wires in a conduit pipe?
Except for the ground wire they must be insulated.
What's the different between white and green wires?
white wires are neutral. green wires are ground wires.
Is a copper wire a ground wire?
Yes, if it is not an insulated wire. If it is bare copper it is always ground. But the hot and neutral wire are also copper, they are just insulated.
My light fixture has writing on one wire but not the other?
If both wires are black then the one with the writing is the neutral wire. If the two wires are black and white then the white one is the neutral.
How many wires in a single phase motor?
There should be 2 or 3 wires. A hot, a neutral and sometimes a ground.
Why aluminium wires are not insulated?
Aluminum wires are insulated.
Why are conducters used in domestic wiring insulated?
Wires are insulated to stop a short circuiting between the common neutral wire and the wire that supplies the potential voltage to the load of the circuit.
What will happen if wires are not insulated?
what may happen if wires are not insulated
Can a insulated ground wire be used in lieu of a tinned bare ground wire?
Yes, as long as it is the same size wire or larger as the hot and neutral wires.
Are wires insulated to keep then warm?
Most are insulated to keep them from grounding out or interference.
Why is an insulated ground wire used in a 3 phase 4 wire system?
A three-phase 4-wire system has three live wires and a neutral, which is earthed at at least one point at the transformer. All current-carrying wires are insulated in this system, for safety. The voltage on the neutral might be zero or only a volt or two, but under fault conditions its voltage could be much higher.
What are insulated wires made out of?
An insulated wire is made of a conductor surrounded by an insulating 'jacket'.
Can you run insulated wires in a conduit pipe?
Except for the ground wire they must be insulated.
What cases eletricity?
Insulated wires and such and batteries.
Why are most electrical wires surrounded by non-metallic materials?
Wires have to be insulated from each other to confine the current inside the wire. Most wires are insulated with a pvc sheath surrounding the copper wire.
What does neutral do?
Neutral wires are actually ground wires. They enable the circuit to be completed.
Which does not state a principle related to why ground wires are in effective safety device?
Electronic devices are protected from power surges by having insulated wires
