How does cable oil filtration improve the performance of electrical cables?

Cable oil filtration removes solid particles and impurities from the oil, enhancing its insulating and cooling capabilities. Clean oil reduces the risk of electrical discharge and overheating, which can damage the cable’s insulation and conductors. By maintaining oil purity, filtration helps ensure consistent electrical performance, reduces energy losses, and minimizes the likelihood of cable failures, thereby improving the overall efficiency of the power transmission system.
