Answer: OPGW live line installation is a highly specialized task that requires meticulous planning and adherence to strict safety protocols. The primary concerns are electrical hazards from the energized phase conductors and induced voltage, which can pose a significant risk to workers and equipment. Key safety measures include:

• Proper Grounding: The use of specialized grounding rollers and insulated equipment to ensure all metallic components are safely grounded to the tower.

• Insulation: Employing insulated pulling ropes and anti-twist devices to prevent accidental contact with energized lines.

• Specialized Equipment: Using tools like mobile traction machines that can safely run along the existing earth wire, keeping workers at a safe distance from the energized conductors.

• Proximity and Clearance: Strict adherence to minimum approach distances (MAD) to the live conductors at all times.
