So, the main purpose of an insulator is to isolate the current from being ground anywhere before the circuit completion. These insulators are essential for safety and they prevent direct contact from live wires.

Materials that don't allow electrons to flow freely are called?
They are called "insulators" and include such materials as glass, rubber, plastic, nylon, dry wood, ceramic, air, etc.
What is the purpose of insulator in overhead transmission line?
Overhead lines are uninsulated, as they depend upon the air to provide insulation. However, they must still be insulated from the towers or poles from which they are suspended. This insulation is provided using glass or ceramic insulators. The greater the line voltage, the longer the ceramic insulator, or the greater the number of glass insulator 'dishes'.
Creepage distance in insulators?
It is the shortest distance between the conductors measured along with the surface of insulators.
What is the name of two insulators?
Insulators in electricity can be glass or ceramic.Insulators in heating can be polystyrene or fibre panels.
Are overhead power lines insulated?
Overhead power lines are insulated from ground, typically using strings of glass or ceramic insulators. The wire itself is bare, though - it does not have insulation on it. There are many different types of overhead power line, but I'm not aware of any that actually have insulation.
Materials such as glass or ceramic that resist the flow of electricity?
"Insulators"
What do you call those ceramic things on the top of phone lines?
Insulators.
Which part of a spark plug is make of corn?
The insulators which are made of ceramic uses corn in the production of said ceramic. Amazing
What are 5 examples of insulators?
Wood plastic mica rubber ceramic and slate
What are ceramic insulators used for?
Ceramic and porcelain insulators are used in conjunction with wires that may generate a large amount of heat. Ceramics have a very high heat tolerance, especially higher than plastic and some metals.
Should the ceramic tiles on a shuttle be good thermal conductors?
No. They should be good thermal insulators.
What insulation can be used around a fireplace?
Asbestos sheet, ceramic or marble may be used as insulators.
What insulators are used for spark plugs?
Mostly spark plug insulators are made from a substance known as sintered alumina,which is a very hard ceramic material with a high dielectric strength.
Why must pylons have ceramic discs?
Pylons must have ceramic or glass insulators to support overheard lines; this prevents the pylons from becoming "live."
Materials that don't allow electrons to flow freely are called?
They are called "insulators" and include such materials as glass, rubber, plastic, nylon, dry wood, ceramic, air, etc.
What is ceramic good for?
Ceramics are very effective as insulators. In fact, they're used on the underside of the space shuttle's body.
Why doesn't ceramic conduct electricity?
Ceramic, like all insulators, doesn't conduct electricity because its outter most shell of electrons is full. Without free electrons, there is no conduction and thus, no current.
