Longer life
All of the above
Answer is Wrong!
Answer is Right!
The correct answer is D. All of the above.
Line supports for transmission lines should possess the following characteristics:
- Low cost: The cost of line supports should be as low as possible, while still meeting the other requirements.
- High mechanical strength: Line supports must be able to withstand the forces exerted on them by the weight of the conductors, the wind, and other loads.
- Longer life: Line supports should be designed to last for many years without needing to be replaced.
In addition to these three main characteristics, line supports should also be:
- Easy to install and maintain: Line supports should be easy to install and maintain, so that they can be kept in good condition and continue to operate reliably.
- Safe: Line supports should be designed to be safe for workers and the public.
- Environmentally friendly: Line supports should be designed to have a minimal impact on the environment.
The specific design of line supports will vary depending on the type of transmission line, the location of the line, and the environmental conditions. However, all line supports should meet the basic requirements of low cost, high mechanical strength, longer life, ease of installation and maintenance, safety, and environmental friendliness.
