The proper installation of single-conductor cables requires a coordinated effort and the use of specialized equipment to overcome the challenges listed above.

1. Preparation and Planning:

   • Route Survey: Before starting, the entire route must be surveyed, and pull tensions and sidewall pressures must be calculated for every bend and straight section.

   • Cable Placement: The three-phase cables should be pulled simultaneously from separate reels to maintain a consistent lay and prevent twisting.

2. Cable Pulling:

   • Use of Anti-Twist Swivels: It is crucial to use anti-twist Swivels between the pulling rope and the cable grips. This prevents the rotation of the pulling rope from being transferred to the cable.

   • Specialized pulling grips: A wire mesh pulling grip (also known as a cable sock) is attached to the conductor. It's important to use grips with a high safety factor that are correctly sized for the cable's outer diameter.

   • Controlled Pulling Force: A hydraulic cable puller with an integrated tension meter is essential. It provides a constant, controlled pulling force, ensuring the maximum allowable tension is never exceeded.

3. Formation and Cleating: Once installed, the cables must be secured in their final configuration (e.g., trefoil) using specialized cleats. This maintains the required spacing and prevents movement, which could lead to abrasion or damage.
