Industrial Contaminants Adhering To Cable Terminals Can Induce Creepage Discharge.

cable lugs is a crucial component of industrial power systems, responsible for ensuring a stable flow of electrical energy. However, when industrial contaminants accumulate on the wire lugs surface, they can cause a range of electrical problems, particularly creepage discharge. Creepage discharge, typically referring to partial discharge phenomena on the surface of electrical equipment, can rapidly affect the performance of electrical equipment and even cause serious equipment damage.

Pollutants such as dust, oil, and chemicals in industrial environments often form a thin film on the surface of electrical lugs. This film increases the conductivity of the electrical equipment surface, causing surface discharge. Over time, these discharges gradually expand, eventually leading to creepage discharge. The effects of pollutants on terminal lugs vary depending on their type and concentration. High humidity or large temperature differences in environmental conditions make it easier for these contaminants to adhere, further accelerating the occurrence of discharge.
