There are a number of ways copper wire can be insulated - or has been insulated in the past - but today, the most common insulating material for copper wire (by no means the only one, though), is vinyl/plastic.

∙ 8y agoThe conductor used in electro magnetic coils is called magnet wire. It has a varnish coating that is used as an insulation to keep the coils of wire from shorting out against each other. This same type of wire is used in motor windings. Without the insulation on the conductor the coil would not work. It would short circuit at the point where the voltage was applied to the coil. As the current takes the path of least resistance it would short circuit at the two connection points of the coil and trip the circuit breaker or fuse disconnecting the circuit from the voltage supply.

Is the silver speaker wire copper?
Yes; it is tinned copper.
Is the gold or copper wire or the silver wire positive?
It doesn't really matter, as long as you connect them to the same polarity at both ends. Most people use the gold or reddish-copper wire as the positive, as it is the red terminal and the silver, or non-colored lead to the negative as it is black.
Can you replace Ni-chrome wire with silver or copper wire?
No. Ni-Chrome wire is resistance wire used in pottery and as a heating element for pyrotechnics. There is no application for Home Theater for this wire.
If speaker wire is silver and copper which one is positive?
Whichever one you connect to the positive terminal. The colors are there so you can find the same wire at the other end.
What cable consists of a single copper wire surrounded by layers of plastec and is used to connect cable TV?
coaxial cable is what most (all) cable providers use
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.
Copper wire weight?
Weight of copper wire is measured by the American Wire Gauge. Determining factors are whether or not it is solid wire, insulated and the area.
How big around is copper wire mcm 750?
The diameter of an insulated 750 MCM copper wire is 1.25 inches. The insulated 750 MCM copper wiring has 61 strands and has a weight of 2.7 pounds per foot.
Why does copper wire have to be insulated?
To stop the conductor from touching adjacent grounded structures.
What happens if the insulation is removed from the copper insulated magnet wire?
No it does not attract to magnets
What is in an electric wire?
An Electrical wire is used to flow the electrons from one point another point . Copper or aluminum is insulated with polythine is called wire
Is it safe to breathe in the fumes from heated copper wire?
Hot copper wire gives off no fumes.However if you are talking about insulated copper wire, the insulation will give off fumes. Depending on the type of insulation it can be anywhere from totally safe to deadly!
What wire channel consists of an insulated copper wire wrapped in a solid or braided shield placed in an external cover?
coaxial cable
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.
Is copper wire a insulating wire?
yes Polyvinyl Chloride (PVC), and rubber are both good insulator's
What is primary wire?
Primary wire is a type of insulated copper wire used mainly for the electronic connections in automobiles and other low voltage electrical equipment.
Why is the three-layer insulated coil less prone to short-circuit failure?
Coiled around copper core wire, no flow blocking element. Why is this insulated wire coil not prone to short-circuit failure?
