Power energy hte seng nna, red copper rods ni gaw, kaja ai conductive network ni hpe gawgap na matu, madung arung arai ni rai nga ai. Hpa majaw nga yang, n-gun kaba ai-n-gun dat dat ai lam ni a busbar kaw nna, transformer windings ni du hkra, shi a n-gun dat dat ai lam sum ai lam hpe hkrak sha shayawm ya lu ai. Statistics hku yu yang, red copper conductive components ni hpe jai lang ai power system ni a hkum tsup ai n-gun atsam gaw aluminum hka htung ni hta 15% kaw nna 20% daram grau law ai.
