The increasing frequency and intensity of extreme weather globally necessitate significant adaptations to power lines to enhance grid resilience:

• overhead line Hardening:

  • Stronger Structures: Replacing older poles with more robust materials like steel, concrete, or composite poles that can withstand higher wind loads and seismic activity.

  • Advanced Conductors: Installing high-strength, high-temperature low-sag (HTLS) conductors that are less prone to breaking under heavy ice loads or extreme heat.

  • Enhanced Vegetation Management: Implementing more rigorous, data-driven tree trimming programs (often using LiDAR for precise mapping) to create wider clearances and prevent tree-related outages.

  • Automated Reclosers and Sectionalizers: Smart devices that automatically detect a fault, temporarily interrupt power, and if the fault is momentary (e.g., a tree branch hitting a line), restore power quickly. If the fault is permanent, they isolate the damaged section, minimizing the affected area.

• undergrounding:

  • Strategic Burial: Selectively moving overhead distribution lines underground in high-risk areas (e.g., urban centers, wildfire-prone zones, hurricane-prone coastlines) provides maximum protection from weather-related damage, although it is significantly more costly and complex to repair. Our specialized underground cable laying equipment facilitates such projects.

• Smart Grid Technologies:

  • Real-time Monitoring: Sensors deployed along both overhead and underground lines provide real-time data on performance and conditions, allowing for proactive intervention.

  • Self-Healing Grids (FLISR): Automated systems that can rapidly detect, isolate, and reroute power around a damaged section, restoring service to unaffected areas within minutes.

• Microgrids: Developing localized power systems that can disconnect from the main grid during an outage and operate independently, providing essential power to critical facilities or communities.

Our comprehensive range of equipment, from robust tension stringing machines for overhead lines to advanced trenching and pulling equipment for underground cables, directly supports these critical resilience-building initiatives worldwide.
