How do various types of conductor grips/pulling socks differ, and what are their specific applications?

2025-07-20

Conductor grips (often called pulling socks, Kellems grips, or cable stockings) vary significantly based on application and conductor type:

  • Single Eye Grips: Most common, used for pulling a single conductor. The pulling line attaches to a single loop or thimble at one end.

  • Double Eye Grips: Have an attachment loop at both ends, allowing for the pulling-in of a new conductor while simultaneously pulling out an old one, or for specific re-tensioning tasks.

  • Offset Eye Grips: Designed to provide a specific angle of pull or to bypass obstacles.

  • Open-End / Lace-Up Grips: These grips can be wrapped around the conductor and then laced up. They are ideal when the conductor end is not accessible or when repairing a section of line.

  • Heavy-Duty Multi-Weave Grips: Feature multiple layers of wire mesh for extremely high tensile strength, used for very large, heavy conductors or for pulling multiple conductors (bundle stringing).

  • Fiber Optic (OPGW/ADSS) Specific Grips: Designed with extra care to provide a gentle yet secure grip on sensitive fiber optic cables without crushing or damaging the delicate internal fibers. They often feature a longer length and finer weave.

  • Rotating Eye Grips: Include an integrated swivel to prevent twisting between the pulling line and the conductor, similar to standalone anti-twist swivels.

  • Live-Line Grips: Specifically designed for use on energized conductors, often with features for remote operation and enhanced insulation.

Each type is carefully selected based on the conductor material, diameter, pulling force required, and the specific stringing methodology.
