How do your stringing machines ensure minimal damage to sensitive conductors like OPGW or bundled conductors?
2025-07-20Protecting conductors from damage is a core design principle for our stringing machines:
-
Multi-Grooved Bullwheels: Our pullers and tensioners feature precisely machined, multi-grooved bullwheels, often lined with high-quality, non-abrasive materials (like specific rubber compounds or polyurethane) to provide a firm grip without crushing or scratching the conductor's surface.
-
Large Bullwheel Diameter: Larger diameter bullwheels reduce the bending stress on the conductor, which is particularly critical for large conductors or those with sensitive internal components like OPGW.
-
Synchronized Control: Our machines are designed for synchronized operation between pullers and tensioners, ensuring consistent tension and preventing slack or excessive stress points along the line.
-
Anti-Twist Technology: When handling OPGW or bundled conductors, our systems are optimized to work with anti-twist swivels and appropriate pulling techniques to prevent torsional stress.
-
Pre-set Tension Limits: Operators can pre-set maximum pulling force or tension limits, and the machines will automatically adjust speed or stop if these limits are exceeded, preventing conductor overstress.
