Tension stringing is the preferred and often mandatory method for installing power line conductors due to its significant advantages over traditional "slack" or "drag" methods:

• Conductor Protection:

  • Slack Stringing: The conductor is allowed to drag on the ground or over obstructions, leading to nicks, scratches, and damage to its surface. This can compromise the conductor's structural integrity, increase corona losses, and lead to premature failure.

  • Tension Stringing: The conductor is kept elevated off the ground and under continuous tension from the reel throughout the entire stringing process. This prevents physical damage, preserving the conductor's integrity and extending its lifespan. Our hydraulic pullers and tensioners are specifically designed to maintain this precise, continuous tension.

• Safety:

  • Slack Stringing: Poses significant safety risks as the conductor can whip unexpectedly, come into contact with energized lines, or create tripping hazards on the ground.

  • Tension Stringing: Provides controlled conductor movement, greatly reducing the risk of accidental contact with energized lines, existing structures, or ground personnel. It is mandatory when stringing conductors over or adjacent to energized power lines, communication lines, roads, railways, or other critical infrastructure to prevent accidental contact.

• Efficiency & Speed: Tension stringing, while requiring specialized equipment, can often be faster and more efficient for long spans and challenging terrains, as it reduces the need for extensive ground preparation and continuous manual handling.

• Precise Sag & Tension Control: Critical for achieving the exact design sag and tension, which impacts line performance, clearances, and longevity. Tension stringing allows for much finer control over these parameters.

• Environmental Impact: By keeping conductors off the ground, tension stringing significantly minimizes ground disturbance, soil erosion, and damage to vegetation along the right-of-way, making it a more environmentally friendly method.
