What are the critical considerations for tension stringing over existing energized lines or sensitive infrastructure (e.g., roads, railways, communication lines)?
2025-07-19Stringing over energized lines or sensitive infrastructure is one of the most hazardous and technically demanding aspects of tension stringing. Critical considerations include:
-
Absolute Minimum Approach Distances (MAD): Strict adherence to statutory and company-specific Minimum Approach Distances from energized conductors is paramount. Tension stringing is the only safe method as it keeps the conductor continuously off the ground and under control.
-
Comprehensive Risk Assessment & Method Statement (RAMS): A detailed, site-specific RAMS must be developed, reviewed, and approved by all stakeholders. This includes detailed stringing charts, emergency procedures, and contingency plans.
-
Robust Grounding & Bonding: All stringing equipment, pulling ropes, pilot lines, and relevant structures must be properly grounded and bonded to mitigate hazards from induced voltages or accidental energization.
-
Specialized Overhead Protection: The use of protective measures like "rider poles," "guard structures," or "rope baskets" over existing lines or infrastructure is crucial to prevent accidental contact if a conductor should fall or sag unexpectedly.
-
Dedicated Spotters and Communication: Trained spotters with clear visibility of the entire operation are essential. Flawless communication (e.g., two-way radio, hand signals) between the puller operator, OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner operator, spotters, and all ground personnel is non-negotiable.
-
Controlled Speed and Tension: Maintaining strict control over stringing speed and tension is vital to prevent sudden movements, whipping, or uncontrolled sag that could lead to contact.
-
Environmental Monitoring: Closely monitoring weather conditions (wind, lightning, precipitation) and ceasing operations if conditions become unsafe.
Our tension stringing equipment is engineered to facilitate these stringent safety protocols, providing the precise control and reliability needed for high-risk stringing operations. We emphasize that proper training and adherence to safety guidelines are as crucial as the equipment itself.
