Maximum Allowable Pulling Tension with a Pulling Eye
The equation below calculates the maximum pulling tension if a pulling eye is attached to the conductor.
Tmax = KA
|
Where: |
Tmax = Maximum pulling tension (lb) K = 10,000 PSI for copper; 7,500 PSI for aluminum A = Area of conductor (sq in) |
Maximum Pulling Tension (Tmax) Using Pulling Eye
The following table shows Tmax for a standard single conductor (1/C) cable.
