The maximum pulling tension is the highest amount of longitudinal force that can be safely applied to a cable during installation without causing permanent damage to its conductors or insulation. This value is a fundamental safety and integrity limit set by the cable manufacturer. It is primarily determined by the yield strength of the cable's conductor material, typically copper or aluminum, and the total cross-sectional area of the conductors.

Exceeding this limit can cause invisible internal damage that leads to premature cable failure, including:

• Stretching: The conductors can stretch and thin out, reducing their cross-sectional area and increasing electrical resistance.

• Insulation Damage: The cable's insulation can be compromised, leading to a risk of short circuits or electrical breakdown over time.

• Conductor Breakdown: In severe cases, the conductors can break completely, rendering the cable unusable.
