Allowable stress at room temperature, copper is 7~28% higher than aluminum. Especially the stress at high temperatures, the difference between the two is even more distant.
Allowable stress at room temperature, copper cable is 7~28% higher than aluminum cable. Especially the stress at high temperatures, the difference between the two is even more distant.
The copper core has high mechanical strength and can withstand large mechanical tension, which brings great convenience to construction and creates conditions for mechanized construction.
