What is a power line insulator?
Power insulators 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 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 is line insulation?
The insulation of pipeline is done to preserve the temperature inside the line. The insulated pipes can be vertical or horizontal stretched all over the plant carrying various liquids. Proper temperature can be maintained with minimum heat loss through proper insulation. …
What is the purpose of line insulator?
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….Suspension insulators.

What is the purpose of an insulator?
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.
How do power line insulators work?
An electrical insulator is a material in which electric current does not flow freely. In addition, all insulators become electrically conductive when a sufficiently large voltage is applied that the electric field tears electrons away from the atoms. This is known as the breakdown voltage of an insulator.
What are the different types of insulators in power system?
Insulator Types
- Pin-type insulators. These insulators are used for the transmission and distribution of electric power at voltages up to 33 kV.
- Line post insulators.
- Suspension insulators.
- Strain insulators.
- Shackle insulators.
- Post insulators.
- Cap and pin insulators.
- Stay insulators.
What is line insulator What are the useful factors for the design of line insulator?
Overhead line insulators should have the following properties: high mechanical strength in order to withstand the conductor load, wind load etc. high electrical resistance in order to minimize the leakage currents. high relative permittivity of insulating material so that the dielectric strength is high.
What is insulator and types of insulator?
Insulators consist of different types of insulator materials like plastic, rubber, mica, wood, glass, etc. In the electrical system, specific insulating materials are used like porcelain, glass, steatite, polymer, ceramic, PVC.
