Initial installation of underground lines is substantially more expensive, often costing several times more than overhead lines. This is because it involves extensive civil work like digging trenches and backfilling. Maintenance costs for both systems can be similar, but repairs on underground lines are generally more complex, time-consuming, and thus more costly. Our company provides equipment for both types of projects, including tension stringing equipment for overhead lines and specialized tools for underground cable laying, to support these critical infrastructure needs.
