It just means that the bare wire is insulated by a non-conducting coating. In home wiring the typical circuit has a black wire (Hot), a white wire (Neutral) and a bare wire which is ground.

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.
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.
Why are some acr tubing lines insulated?
if not insulated, condensation will accumulate.
What is a Black wire in a household circuit?
Answer for USA, Canada and countries using similar 60Hz household electrical servicesBlack insulated wire is used for a "Hot" (or "Live") wire. Answer for European and other countries using similar 50Hz household electrical services In old wiring, as was used for household electrical circuits installed in the UK prior to 2006, the "Neutral" would have been a black insulated wire. Black insulated wiring is not used for that purpose today. For more information see the answers to the Related Questions shown below.
What is the color of the earth wire live wire and neutral wire?
In the US older 2-conductor house wire has a white-insulated and a black-insulated wire. The white wire is the neutral and the black is the hot wire. Newer house wire has a third bare copper wire to serve as the ground wire. Insulated ground wire has a green jacketing on it. Red wires are for switch legs. You want to be sure that whomever did the wiring didn't flip the colors around. You can do this by checking the fuse or breaker box - the white or neutral wires should all run to the multi-neutral ground bus bar and the black or hot wires should each go to their respective circuit breakers or fuse sockets. On your switches and recepticals, the gold screw is for the black, or hot wire, and the silver screw is for the neutral. The green screw would be for the ground wire. Mostly, use a qualified electrician to do any work unless you are quite handy, have all necessary tools and fully aware of all safety precautions and code requirements that may exist where you live.
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.
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.
Why marine electrical generation and distribution employs an insulated neutral?
because insulated neutral is to avoid the shock The aystem will allow essential critical equipment to continue to run even though there may be a loss of insulation, however if two phases become dgraded to warth the advantage is lost
Can a type SE cable with an insulated neutral be used to feed an electric range through a sub-panel?
check your local codes for this

Do powerline neutral wires have to be insulated?
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.
A sentence with the word insulated?
I can give you several sentences.The house is insulated against lightning strikes.Wear your insulated boots out in the snow.She is insulated by layers of clothing.
Why aluminium wires are not insulated?
Aluminum wires are insulated.
Can you applied the voltage to neutral of the transformer?
The neutral of a transformer is usually grounded. Under this situation, this question is the same as asking whether you can apply a voltage to ground; the answer is yes, but I don't know why you'd want to. Sometimes transformer neutrals are insulated away from ground. If this is done, then you could inject "backwards" from the neutral up into the transformer. Again, I don't know why you would want to do this, though.
What is the Difference between air insulated substation and gas insulated substation?
Air insulated substation means air acts as the dielectric medium but in case of gas insulated substation SF6 is the dielectric medium. Gas insulated substations are having more advantages than air insulated substations.
