Potential Risks Of Cold-pressed Needles During Perforation Connection

In cable connection operations, improper operation and control of the male crimp contact piercing connection method can damage the internal structure of the conductor. This manifests as conductor breakage, reduced cross-sectional area, and microcracks; these hidden defects often only become apparent during later operation.

When piercing with a crimp contact piercing method, deviations in pressure, angle, or die positioning can cause localized crushing or breakage of the copper conductor. The reduction in cross-sectional area leads to increased contact resistance, heat buildup, and accelerated aging. Meanwhile, while microcracks may not immediately affect the energizing state, they can gradually expand under load fluctuations, thermal cycling, or vibration, ultimately causing connection failure or shortened lifespan.
