Maintaining OHTLs presents several challenges, particularly as infrastructure ages and weather events become more severe. The main issues include:

• Environmental Damage: Harsh weather conditions like high winds, ice, and lightning can cause significant physical damage to towers and conductors.

• Corrosion and Deterioration: Over time, components like conductors and hardware can corrode, particularly in coastal or polluted environments, reducing their structural integrity.

• Vegetation Management: Keeping trees and other vegetation clear of the lines is an ongoing task to prevent outages and maintain safety clearances.

• Aging Infrastructure: Many older transmission lines require frequent inspection and potential replacement to ensure they meet modern safety and reliability standards.

These challenges are typically addressed through regular, proactive maintenance programs, including visual inspections, aerial patrols (often using drones), and modern condition monitoring technologies that can detect faults and deterioration early. At Ningbo Changshi, we design our equipment with durability and ease of maintenance in mind to help our clients overcome these challenges.
