In the field of power equipment manufacturing, the fraudulent practice of using "aluminum instead of copper" in transformers is becoming a serious threat to public safety and industry reputation. This phenomenon refers to manufacturers illegally substituting high-conductivity copper windings with al

Transformers, often regarded as the backbone of modern electrical systems, play a crucial role in efficiently transmitting and distributing electricity. By converting alternating current (AC) voltage levels, transformers ensure that power can be safely and effectively used across various application
