Industrin för kraftkablar av aluminiumlegering: metallurgi, krypning och anslutningsproblemet
Aluminum is an excellent conductor and a difficult material to connect. Under sustained terminal pressure it creeps—slowly deforming until the joint loosens, resistance rises, and heat builds. It also forms an insulating oxide layer within minutes of exposure to air, which must be broken and kept broken for a joint to conduct. These two properties explain why aluminum wiring acquired a...
