The pulling tension for a 132kV cable must be meticulously managed to protect its integrity. It is determined by the cable's conductor material and total cross-sectional area, and it is calculated using the same fundamental formula as lower-voltage cables, but with a heightened emphasis on precision.

The maximum pulling tension (Tmax) is calculated as:

Tmax=K×S

• K is the constant for the conductor material (50N/mm2 for copper; 30N/mm2 for aluminum).

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

For 132kV installations, the process goes a step further. We recommend our puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioners that feature an automatic overload protection system. If the pulling tension approaches a pre-set limit, the machine automatically slows down or stops the pull, preventing dangerous over-tensioning and protecting the cable from irreversible damage.
