1. Types of Cable Pulling Grips

  1. Single-Eye Cable Grip

    • Most common type.

    • A steel wire mesh with one pulling eye at the end.

    • Used for standard underground cable pulls.

    • Eye is attached to pulling rope or swivel.

  2. Double-Eye Cable Grip

    • Two pulling eyes for stronger anchoring.

    • Provides better load distribution and reduces slippage.

    • Suitable for long or heavy cable pulls.

  3. Lace-Up (Split) Cable Grip

    • Opens along the side and laces up around the cable.

    • Useful when you cannot access the free end of the cable.

    • Common in maintenance or repair projects.

  4. Offset-Eye / Rotating-Eye Grip

    • Offset eye: Used when pulling at an angle.

    • Rotating eye (with swivel): Prevents cable from twisting during pulling.

    • Recommended for long duct pulls or overhead line OPGW stringing.

  5. Double-Weave or Triple-Weave Grips

    • Stronger mesh construction for high-tension pulls.

    • Reduces risk of cable slippage or grip breakage.

  6. Conductor / Wire Mesh Grip (for overhead lines)

    • Designed for ACSR/AAAC/OPGW conductors.

    • Different from underground cable grips.

 2. How to Choose the Right Grip

A. Cable Diameter

  • Always match grip size to cable outer diameter (OD).

  • Grips are specified in a range (e.g., 50–60 mm).

  • Too small → can damage cable sheath.

  • Too large → grip may slip off under load.

B. Pulling Tension

  • Check grip’s rated breaking strength.

  • Must be greater than the maximum pulling tension (plus 25–30% margin).

  • Heavy transmission cables may require double-weave grips.

C. Cable Type & Application

  • LV/MV underground power cables → Single-eye grips.

  • HV/EHV long duct pulls → Double-eye or double-weave grips + swivels.

  • Fiber optic / OPGW stringing → Light-duty mesh grips with rotating eye.

  • Retrofit projects (no free end) → Lace-up grips.

D. Pulling Method

  • Straight trench pulls → Single-eye grips.

  • Duct pulls with bends → Grips with rotating eyes (to avoid twist).

  • Overhead line stringing → Conductor grips sized for specific conductor type.

E. Environment

  • Underground ducts with lubricant → Stainless steel or galvanized steel grips.

  • Marine or corrosive environments → Stainless steel only.

 3. Practical Selection Steps

  1. Measure cable OD accurately.

  2. Check max pulling tension (from cable manufacturer).

  3. Select grip type:

    • Single-eye → simple, short pulls.

    • Double-eye / double-weave → long, heavy pulls.

    • Rotating-eye → duct pulls with multiple bends.

    • Lace-up → retrofit/no free end access.

  4. Ensure breaking strength > pulling tension.

  5. Always use with a swivel joint to prevent torsion.

Rule of Thumb:

  • Distribution projects (LV/MV) → Single-eye grips.

  • Sub-transmission (66–132 kV, long ducts) → Double-eye, rotating-eye, or lace-up depending on conditions.

  • Transmission (220–765 kV overhead) → Special conductor grips sized for ACSR/AAAC/OPGW.
