This analysis demonstrates the effects of impurities on heating temperature in copper wires, suggesting significant implications for electrical safety.
Key Points
Heating temperature of electric wires varies with the chemical composition of the conductor's impurities.
Temperature-time characteristics showed that wires with iron impurities heated to the highest temperatures at different currents.
Increased impurity levels in copper conductors resulted in higher heating temperatures for electric wires.
Modeling demonstrated critical temperatures of electric wires based on impurity volumes and loads.
