What are the advantages of suspension insulators over string insulators?
What are the advantages of suspension insulators over string insulators?
Advantages of Suspension Type Insulator The string is free to swing in any direction and, therefore, great flexibility is provided to the transmission line. The conductors are placed below the suspension insulators and hence it partly protects the conductor from lightning.
Where suspension insulator is mainly used?
The suspension type insulators are generally used with the steel towers.
What are the disadvantages of insulators?
CONS
- Not waterproof and prone to moisture.
- Vulnerable to rot and mold when it gets wet.
- Not an air barrier, so it must be paired with air sealing to meet ENERGY STAR standards.
- Low R-value of up to R-3.7 per inch when compared to spray foam insulation.
What are the main advantages of pin insulators?

- It is not expensive.
- It has a good creepage distance.
- It is applicable to a high voltage transmission line.
- The designing of this insulator is simple.
- Easy maintenance.
- It is used vertically & horizontally.
What are the advantages and disadvantages of insulation?
Advantages & Disadvantages of Wall Insulation
- Advantage—Energy Efficiency.
- Advantage—Friendly to the Environment.
- Advantage—Noise Reduction.

Why are suspension insulators used on high voltage cables?
This arrangement provides partial protection from lightning. The suspension arrangement provides greater flexibility to the line. Suspension insulators are allowed to swing so that they can take up the position where mechanical stresses are minimum.
Where is the suspension type of insulators mainly used Mcq?

What are the advantages and disadvantages of insulator?
Advantage: Most common, non-flammable, resistant to moisture damage, and effectively blocks heat flow. Disadvantage: It can be highly irritating to your skin and lungs if you come in direct contact with it. Installation: Fairly simple, and you can do it yourself.
What is suspension insulator?
Suspension insulators support transmission lines on steel towers, isolating the lines from the tower. They play a key role in the safe supply of electricity. Based on the transmission voltage and usage environment, suspension insulators are used in configurations of two or more.
What are the benefits of insulation other than heat loss heat gain?
Insulation is used in buildings and in manufacturing processes to prevent heat loss or heat gain. Although its primary purpose is an economic one, it also provides more accurate control of process temperatures and protection of personnel. It prevents condensation on cold surfaces and the resulting corrosion.
What are the advantages and disadvantages of cavity wall insulation?
They can reduce the risk of moisture, condensation build up and penetrative damp problems. The cavity wall can reduce the heating cost of a building. As the air in the cavity works as an insulator. They offer good sound insulation compared to a property with a solid brick wall, reducing the effect of external sound.
What are the advantages of transmitting electrical power at high voltages?
The primary reason that power is transmitted at high voltages is to increase efficiency. As electricity is transmitted over long distances, there are inherent energy losses along the way. High voltage transmission minimizes the amount of power lost as electricity flows from one location to the next.
