Structural Risk Analysis Caused By Insufficient Strength Of Cable Terminal Materials

The material strength level of Compression Cable Lug directly affects the mechanical properties of the connection point and the overall system stability. The industry also sets specific requirements for the mechanical load-bearing capacity of cable lugs. For example, threaded clamping terminals must possess sufficient mechanical strength, and soft metals prone to deformation or creep should not be used as terminal materials; otherwise, poor contact or fatigue failure may occur when fixing the conductor.

When the strength of wire lugs material is insufficient, deformation, cracks or even breakage are likely to occur in the stressed area. This physical damage will reduce the load-bearing capacity of the connection point, thereby affecting the conductivity stability of the cable. Insufficient material mechanical properties may also lead to loosening or displacement under dynamic load environments such as vibration and thermal cycling, increasing the probability of electrical failures.
