Detailed Solution
Download Solution PDFThe Correct answer is option 3):((a), (b) and (c))
Concept:
- Wooden poles, steel poles, RCC and PCC poles are used for distribution purposes and steel towers are used for transmission purposes.
- Line support plays a major role in power transmission.
- It kept the proper spacing between the conductors and maintained the conductor at the prescribed distance from its ground parts.
- It also maintained the specified ground clearance.
- These clearances are decided by electrical and mechanical considerations.
- The line supports should have high mechanical strength so that they can withstand the weight of conductors and wind loads, etc. It should be light in weight without loss of its mechanical strength. It should have a longer life. It should be cheap in cost and economical to maintain
- It should be light in weight without the loss of mechanical strength.
