Answer: The construction of a 220kV overhead transmission line requires a comprehensive suite of specialized tools and equipment to ensure safety, efficiency, and reliability. Key components include robust transmission towers (lattice or steel poles), high-performance conductors (such as ACSR), and various types of insulators (glass, porcelain, or polymer). The construction process, particularly the conductor installation, relies heavily on advanced tension stringing equipment, including hydraulic pullers, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners, and anti-twist ropes.
