There are a number of reasons:
If the wire is electrical then it is covered in plastic as plastic provides insulation, this means that if adjoining wires come into contact the electrical current would not cause a short circuit. Normally electrical wire is cooper as it is a good conductor of electricity and does not oxidize/ rust easily.
Secondly wire hangers are covered in plastic to prevent the metal (normally mild steel) from rusting. If they were to rust, it would cause orange/ red stains on your clothes.
What else can I help you with?
What metal is used in household electric wiring?
Yes, because to conduct electricity you need a metal wire, (usually copper). However they have a plastic outer coating (sheath) which protects them and insulates them.
What factor can change the amount of resistance in a wire?
Rubba Bubba Rubber coating, around the wire
Why is a plastic coating around a wire?
A plastic coating around a wire is used to provide insulation and protection. It helps to prevent electrical shocks, short circuits, and corrosion. It also helps to keep the wire stable and maintain its shape.
Is wire metal non metal?
The wires themselves are usually made of a metal such as copper.
Is wire metal or non metal?
The wires themselves are usually made of a metal such as copper.
Why is it important that the material around wire be made of a substance other than a metal?
The coating on a wire is there to insulate it from contact with people, and other wires. The material will always be conducting. Good materials are rubber, plastics, glass. Metal would be the worst type of outer materials because it would conduct the electricity.

Is wire coating an example of thermosetting plastics?
yes wire coating is an example of thermosetting plastics!!!!
What metal is usually used to make a electric wire?
Copper
What is the best insulator for metal wire?
A wire is a conductor. It is usually coated with an insulator to isolate the current flowing in the conductor portion of the wire from other things around the wire, like your hand.
What is characteristics of wire?
A wire has to be made of a conducting metal such as copper or aluminium, and it has to be thick enough to carry the required amount of electric current. Wire is often given an enamel coating to insulate it Wires are often stranded which gives flexibility.
Why one does removes the plastic coating of connecting wires before making circuits?
Because they'll be joined with a connector of some sort (I work in automotive, so it's usually butt connectors). Inside that connector will be metal which will help transfer electrical energy from one wire end to the wire end of the one it's being connected to... plastic is an insulator, and if it's left there, it'll inhibit the flow of electricity.
