Polychlorinated biphenyls (PCBs) were once commonly used in transformer oils due to their excellent insulating properties. However, due to their toxicity and environmental hazards, the use of PCB-containing oils has been banned or restricted in many countries. Transformers that once used PCB oils are being phased out or retrofitted with safer alternatives.
