so it could prevent shocking you .They use that because if u get shocked the electric can travel through your body and it could harm u if u get shocked a lot. Also if u get shocked and you can hurt other people and shock them to so that is why they use plastic coating on the electric cords.

Which plastic is used for making wire insulation?

Electrical insulation on a wire or cable composed of plastic. Most wires and cables use plastic insulation. Some other types of insulation used on wires and cables are: enamel, cloth, natural rubber, gutta percha, ceramic, etc.


What are four good electrical insulators?

Four good electrical insulators are rubber, glass, plastic, and ceramic. These materials have high resistivity, which prevents the flow of electric current, making them ideal for protecting wires and components in electrical applications. Their insulating properties help to ensure safety and efficiency in electrical systems. Additionally, they are often used in various consumer products and industrial applications to prevent electrical shock and short circuits.


Why are electrical cables and wires always covered with rubber or plastic?

AnswerThe rubber or plastic serves as electrical insulation (because they are poor conductors). Without insulation, the electricity running in a bare cable would leap over into any other electrically conducting material it touched. With enough voltage, a human could be electrocuted.Electrical signals would disappear and get lost, causing equipment to fail.AnswerSo the conductor is insulated against possible metal contact & prevent a short if it's grounded.AnswerAll household electric wires are covered with plastic and rubber. This is called insulation. It keeps the potential of the wire from returning to ground (short circuit) before being used by the load. The higher the potential (voltage) the greater the insulation factor has to be. Bare wires in transmission towers also use insulation in the form of air. To use this method, engineered clearances have to be maintained between the conductors.AnswerAll electrical power wires are covered with an insulating material. This is to prevent the potential on the wire from going anywhere except to the load.Electrical connecting wires are covered with plastic to prevent the wire under the covering from shorting out against each other or shorting out to ground. The electrical terminology for this covering is the wire's "insulation".These days most electrical wires are covered with a flexible plastic (rubber starts with the sap from a rubber tree; plastic usually starts with a petroleum base).AnswerThe main purpose of the "cover" (insulation) is to keep the wire from shorting to other objects.The plastics used generally have a good mix of the following properties:It is flexible so the wire can be flexed and bent.It is inexpensive and easy to apply to the wire during manufacturing.It has resistance to chemicals and UV light.Sometimes it's also important for it to resist abrasion or temperature extremes, or submersion in water.You can get wire with different types of insulation depending on what you need it to withstand.


Why are the handles of screw drivers often made of plastic or rubber?

What does a insulator and a conductor mean?

An insulator is a material that prevents the passage of electricity. An example is the plastic insulating cover on electrical wires, A conductor is a material that allows electricity to flow. An example is the copper wire used inside electrical cables.

Is plastic a insulator or condocter?

Plastic is an insulator. It does not easily conduct electricity because its molecular structure does not allow for the flow of electrons. This property is why plastic is used to cover and insulate electrical wires.

Are bad conductors of electricity used to cover electrical wires?

No, materials with a high insulation value factor are used to cover electrical wire to provide a barrier from the wire shorting out to ground. By using the term "bad conductors" states that there is conductivity to a degree.


What are some ways rubber and plastic are used as electrical and thermal insulators?

Plastic and rubber are used to cover electrical cords on most commonly used household electrical devices. You can also find rubber covers under the hood of your car that are used as thermal insulators.

What is material that is often used to insulate wires that conduct electricity called?

The material that is often used to insulate wires that conduct electricity is called electrical insulation. This material helps prevent the flow of electricity between the wires and protects them from damage or short circuits. Common materials used for electrical insulation include rubber, plastic, and fiberglass.
