Answer: Modern overhead transmission lines, particularly aging infrastructure, face several common maintenance challenges. These include conductor degradation, such as corrosion and fatigue from wind-induced vibrations, which can lead to breakage. Insulator failure from contamination or environmental degradation is another frequent issue, as is conductor sagging due to thermal expansion or mechanical stress. Other challenges involve vegetation encroachment, which can cause short circuits, and damage from lightning strikes or severe weather. Addressing these issues requires a combination of regular inspections, often using advanced technologies like drones with high-resolution and thermal cameras, and a well-planned maintenance strategy. Our company provides the specialized tools and equipment, such as tension stringing equipment, that are essential for safe and efficient maintenance and repair operations.
