Answer Posted / Aarti Martolia
Merits:
1. Ease of installation as there is no need for a concrete trench bed.
2. Lower cost compared to installing cables in an RCC trench.nnDemerits:
1. Submerged cables may lead to increased risk of corrosion and electrical faults due to water exposure, which can cause system failure.
2. Difficulty in inspecting or maintaining the cables due to their submerged state.
3. Reduced lifespan of cables due to constant moisture and potential chemical contamination.
