Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air .
What are 3 types of insulators?
- Suspension insulators.
- Pin insulators.
- Strain Insulators.
- Stay Insulators.
- Shackle Insulators.
What are 4 good insulators?
Insulators oppose electrical current and make poor conductors. Some common conductors are copper, aluminum, gold, and silver. Some common insulators are glass, air, plastic, rubber, and wood .
What is a conductor give 3 examples?
Conductor – A conductor is a material which electricity, heat or sound can flow through. ... These metals are used to make wires to carry electric current. Example – Some common conductors are copper, aluminum, gold, and silver . Some common insulators are glass, air, plastic, rubber, and wood.
What are 5 insulators?

What are 2 insulators?
Plastic, wood, glass and rubber are good electrical insulators. That is why they are used to cover materials that carry electricity.
Which type of insulator is used?
| Insulator Voltage capacity Use | Pin insulator < 33 kV Distribution system | Post insulator 11 kV to 765 kV Substation system | Suspension insulator > 11 kV (High) Transmission system | Shackle insulator < 33 kV Distribution system |

Is water an insulator?
Well actually, pure water is an excellent insulator and does not conduct electricity. The thing is, you won’t find any pure water in nature, so don’t mix electricity and water.
What is a stay insulator?
A Stay insulator is a form of low voltage insulators made to counterweight and fasten the dead-end pole by combining stay wire or guy grip . It is also introduced as an egg insulator or stay part. ... Professional stay insulators have the structure to prevent the electric conduction on the main wire by accident.
What is the best insulator?
The best insulator in the world right now is most probably aerogel , with silica aerogels having thermal conductivities of less than 0.03 W/m*K in atmosphere. of aerogel preventing ice from melting on a hot plate at 80 degrees Celsius! Aerogel has its amazing properties because it’s mostly made out of air.
What is a bad insulator?
Metals, especially silver, are good electrical conductors. ... Materials like glass and plastic are poor electrical conductors, and are called insulators. They are used to stop electricity from flowing where it is not needed or where it can be dangerous, such as through our bodies.
What household items are insulators?
Plastic, rubber, wood, and ceramics are good insulators. These are often used to make kitchen utensils, such as saucepan handles, to stop heat from flowing up to burn the cook’s hand. Plastic coating is also used to cover most electrical wires in appliances. Air is also a good insulator of heat.
What are 3 types of conductors?
Many materials are used to transmit electrical energy, but those most frequently specified for types of conductors are copper, copper-covered steel, high strength copper alloys, and aluminum .
What’s the best conductor of electricity?
The best conductor of electricity is pure silver , but to no surprise, it is not one of the most commonly used metals to conduct electricity.
Is a dog a conductor or insulator?
The loose electrons make it easy for electricity to flow through these materials, so they’re known as electrical conductors. ... Dogs that lived inside or within a fenced-in area, thereby keeping those pesky fleas contained, would be the equivalent of an electrical insulator .
