The choice between overhead and underground equipment depends on several project-specific factors:

• Project Location & Environment:

  • Urban/Dense Areas: Undergrounding is often preferred for aesthetics, space constraints, and reduced vulnerability to weather, using trenchers, directional drills, and cable pullers.

  • Rural/Open Terrain: Overhead lines are typically more cost-effective and faster to install using OHTL stringing equipment.

  • Environmentally Sensitive Areas: Tension stringing for OHTL or careful undergrounding methods (like Horizontal Directional Drilling) are chosen to minimize disturbance.

• Cost: Initial installation costs for underground cables are generally significantly higher than for overhead lines due to excavation, specialized equipment, and repair complexity.

• Maintenance & Repair: Fault location and repair are more challenging and time-consuming for underground cables. Overhead lines are generally easier to inspect and repair.

• Reliability & Resilience: Underground cables offer higher resilience against weather-related outages (storms, ice), while overhead lines are more susceptible but easier to diagnose and fix.

• Voltage Level & Capacity: Both methods can handle various voltage levels, but specific equipment types are optimized for each.

• Public Safety & Aesthetics: Undergrounding enhances public safety by eliminating visible wires and poles, improving visual appeal.

• Regulatory Requirements: Local regulations, zoning laws, and environmental policies often dictate the preferred method.

Our company provides comprehensive solutions for both, allowing clients to select the optimal equipment based on their specific project needs and priorities.
