Global Overhead Line Product Market- Restraints

• High costs and long project timelines: The overhead line product market is constrained by substantial capital requirements and lengthy project execution timelines. Building new overhead transmission infrastructure necessitates significant investments in towers, conductors, and cables, amounting to millions of dollars per kilometer of line length. The long planning and regulatory approvals also delay project execution affecting market growth.
• Concerns regarding grid stability and power quality: The stability and reliability challenges associated with overhead lines could restrain market growth. Overhead networks are exposed to environmental factors like storms, birds and vegetation affecting grid stability. Technical issues like voltage fluctuations and frequency disturbances due to VAR flows also affect power quality. Underground cables provide a more stable power supply.
• Permits and public opposition to new projects: Acquiring permits for new overhead transmission projects often involves extensive negotiations and environmental impact assessments causing delays. Also, public opposition due to right-of-way issues for overhead lines running through neighborhoods poses a barrier. These factors are discouraging investment in new overhead line infrastructure in developed regions.
