How To Accelerate The Creepage Process When Cracks Appear On The Surface Of Cable Terminals?

The surface defect of Aluminum Cable Lug will create the shortest discharge path. When the material thickness at the crack decreases or completely breaks, the insulation distance between two conductors with different potentials is significantly shortened. In high-voltage environments, this shortened distance will significantly reduce the breakdown voltage, and Compression Cable Lug will be more prone to creepage.
The accumulation of contaminants at the crack also accelerates the problem. Dust, moisture, and other environmental pollutants tend to deposit inside cracks, forming conductive channels. This combined effect of surface contamination and cracks further lowers the creepage initiation threshold.
