Oil in transformer insulation systems critically safeguards grids, yet microbial contamination catastrophically compromises dielectric integrity, threatening grid resilience worldwide. To address this dual challenge of biocontamination and degradation, we engineered bifunctional copper oxide nanofluids (CuO NFs) through crystallographic tailoring surface charge optimization. Two dominant actinomycetes (Mycoplana Rothia), isolated from operational transformers, achieved up to 98.19% 96.32% inactivation rates when exposed CuO NFs, coupled with a 1.62-fold increase AC breakdown voltage compared base oil, owing the designed monoclinic-phase nanoparticles (+20.14 ± 1.5 mV) that disrupted integrity via electrostatic adhesion reactive oxygen species (ROS) generation, which is first demonstration nanoscale ROS-mediated antimicrobial mechanisms oil-immersed systems. This work provides robust strategy for development NFs mitigate enhance insulating properties.
