The maximum pulling tension for XLPE cables is a critical parameter that must never be exceeded. It is typically determined by the cable's conductor material and cross-sectional area. The formula for the maximum pulling tension (Tmax) is:

Tmax=K×S

Where:

• K is a constant based on the conductor material:

  • K=50N/mm2 for copper conductors

  • K=30N/mm2 for aluminum conductors

• S is the total cross-sectional area of the conductors in mm2.

It is crucial to use a winch or puller with an integrated tensiometer to ensure the pulling force remains below this calculated maximum throughout the entire pull.
