Anti-Twist Swivels are crucial safety and conductor protection accessories, serving the vital role of preventing torsional forces from transferring to the conductor during stringing operations. Without them, the pulling rope's natural tendency to twist under load could cause conductors (especially bundled ones or OPGW) to rotate, leading to damage, unraveling, or compromised optical fibers.

The latest features ensuring their reliability include:

• High-Capacity, Sealed Bearing Systems: Modern Swivels incorporate robust, precision-engineered sealed bearings (e.g., thrust bearings, ball bearings) that allow for free rotation under extreme radial and axial loads. The sealed design protects against dirt, moisture, and corrosion, ensuring smooth operation in harsh environments.

• High-Strength Forged Construction: Swivel bodies are typically forged from high-grade alloy steels, providing exceptional tensile strength and durability to withstand the substantial pulling forces.

• Clear Working Load Limit (WLL) Markings: Each swivel is clearly marked with its WLL and often tested to a higher proof load, ensuring operators select the correct swivel for the anticipated forces.

• Integrated Grease Fittings: While sealed bearings reduce maintenance, some high-capacity swivels still feature easily accessible grease fittings for periodic lubrication, ensuring longevity.

• Compact and Ergonomic Design: Despite their strength, newer designs are often more compact and lighter, making them easier to handle and integrate into the stringing setup.

• Corrosion-Resistant Finishes: Durable coatings or galvanization protect the metallic components from rust and environmental degradation.

These features ensure that anti-twist swivels reliably absorb rotational energy, safeguarding the conductor's integrity and enhancing overall stringing safety.
