RCC poles usually have a span of
RCC poles usually have a span of
- 250 to 500 m
- 100 to 150 m
- 50 to 100 m
- 5 to 50 m
Correct answer: 2. 100 to 150 m
Cross arms used in transmission lines are made of
Cross arms used in transmission lines are made of
- Steel
- Aluminum
- Copper
- RCC
Correct answer: 1. Steel
Practical application of guy wire is to
Practical application of guy wire is to
- Support the pole
- Provide protection against surges
- Provide emergency earth route
- All of these
Correct answer: 1. Support the pole
Galloping in transmission line conductor ascends because of
Galloping in transmission line conductor ascends because of
- Asymmetrical layers of ice formation
- Acceptance of horizontal current configuration
- Vortex phenomenon in light winds
- Heavy weight of the line conductors
Correct answer: 1. Asymmetrical layers of ice formation
