Which insulator is used in overhead transmission line?
The commonly used material for manufacturing the insulators of overhead transmission line is porcelain. Although, glass, polymer and steatite and many other special composition materials are also used for manufacturing the overhead line insulators.
Which conductors are used in overhead and transmission lines?
Types of Conductors :
In the early days conductor used on transmission lines were usually Copper, but Aluminium Conductors have Completely replaced Copper because of the much lower cost and lighter weight of Aluminium conductor compared with a Copper conductor of the same resistance.
What are 10 types of insulators?
10 Electrical Insulators
- Rubber.
- Glass.
- Pure water.
- Oil.
- Air.
- Diamond.
- Dry wood.
- Dry cotton.
Which material is used for line insulators?
Glass and porcelain are the most widely used materials for making insulators.
What are 3 types of insulators?
Among these insulators, strain, suspension and pin insulators are used in medium to high voltage systems, while stay and shackle are mainly used in low voltage applications.
What type of insulators are used?
Post Insulator
| SL | Pin Insulator |
|---|---|
| 1 | It is generally used up to 33KV system |
| 2 | It is single stag |
| 3 | Conductor is fixed on the top of the insulator by binding |
| 4 | Two insulators cannot be fixed together for higher voltage application |
What are 4 types of conductors?
There are four types of conductors, namely, good conductors, semiconductors, resistors and non-conductors. Non-conductors are also termed as insulators.
What are conductors and insulators?
A conductor allows current to flow easily through it. Insulators don’t allow current to flow through it. Electric charge exists on the surface of conductors. Electric charges are absent in insulator. Conductors don’t store energy when kept in a magnetic field.
What are 3 types of conductors?
There are four types of conductors, namely, good conductors, semiconductors, resistors and non-conductors.
Which is an example of conductor?
Examples of conductors include metals, aqueous solutions of salts (i.e., ionic compounds dissolved in water), graphite, and the human body. Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.
What are types of insulator?
The five types of insulators are:
- Suspension insulators.
- Pin insulators.
- Strain Insulators.
- Stay Insulators.
- Shackle Insulators.
What is the name of line insulator?
The shackle insulator (also known as a spool insulator) is usually used in low voltage distribution network. It can be used in both the horizontal or vertical positions. The use of such insulator has decreased recently after increasing the using of underground cable for distribution purpose.
What are 5 types of insulators?

Is water a conductor or insulator?
Water and electricity don’t mix, right? Well actually, pure water is an excellent insulator and does not conduct electricity.
Which is example of insulator?
What is insulator used?
Insulators are used in electrical equipment to support and separate electrical conductors without allowing current through themselves. An insulating material used in bulk to wrap electrical cables or other equipment is called insulation.
What is insulator function?
Electrical insulators are used to hold conductors in position, separating them from one another and from surrounding structures. They form a barrier between energized parts of an electric circuit and confine the flow of current to wires or other conducting paths as desired.
What are the five insulators?
What are 4 types of insulator?
What is example of conductor?
Is oil an insulator?
Oil is an insulator and is a bad conductor of electricity. Complete step by step answer: The oil by nature does not conduct electricity. It does not allow electric current to pass through.
Is salt a conductor?
For example, solid sodium chloride (NaCl, or table salt) does not conduct electricity; it is an insulator. If NaCl is placed into water, the mutual attraction both sodium (Na) and chlorine (Cl) have for water molecules cause their bonds to break (dissolving) and form ions (charged atoms or molecules) within the water.
