Regular inspection and maintenance are vital for OHTL longevity and reliability:

• Visual and Aerial Inspections: Routine checks from the ground, by helicopter, or using drones equipped with cameras and thermal imaging to identify damage, sag issues, or vegetation encroachment.

• Infrared Thermography: Detecting hot spots at connections or clamps, indicating potential overheating or faulty connections.

• LiDAR and Photogrammetry: For accurate mapping of line geometry, sag, and clearance distances.

• Vegetation Management: Proactive trimming and removal of trees within the right-of-way.

• Insulator Cleaning and Replacement: Removing contaminants and replacing damaged units.

• Conductor Repair and Splicing: Addressing localized damage or joining conductor sections.

• Hardware Tightening and Replacement: Ensuring all fittings are secure and replacing worn components. We offer tools and equipment that support all aspects of OHTL inspection and maintenance, helping utilities ensure grid stability.
