Anti-Rotation Device Ensures Safe OPGW Installation on High-Voltage Transmission Line
The Challenge
Root Cause Analysis
- Rotational Stress: Pulling tension can cause the OPGW to rotate, leading to fiber damage.
- Installation Sensitivity: OPGW’s dual role as both conductor and communication medium means any damage during installation can have system-wide effects.
- Line Complexity: Long spans and tension variances increase the risk of torsional strain during overhead installations.
The Solution
Deployment of Anti-Rotation Device
To prevent cable twist during installation, the contractor deployed a specialized anti-rotation device. This equipment ensured the OPGW was pulled evenly and smoothly, eliminating rotational stress that could damage the fibers.Proactive Construction Oversight
Think Power Solutions provided field oversight to verify proper setup, safety protocols, and equipment use throughout the operation. Oversight included real-time observation of the pulling process and confirmation of line tension stability.Experience-Based Execution
The contractor’s familiarity with similar high-voltage installations, combined with early preparation, allowed the team to anticipate challenges and maintain a controlled work environment.Key Benefits
- Fiber Integrity Preserved: No reported damage to the internal fibers of the OPGW.
- On-Time Milestone Completion: Project proceeded without incident or installation delays.
- Safety Assurance: Field teams maintained full safety compliance for both personnel and equipment.
- Technology-Led Risk Mitigation: The anti-rotation device proved to be a simple yet critical tool for high-voltage OPGW installation.
