Mainly depends on strictly according to the national standard process production and the use of high quality cable raw materials |
|
Ampacity (same section) |
high |
Low |
mid |
The conductor cable of the aluminum alloy reaches or exceeds the cut-off of the copper conductor cable by increasing the cross-sectional area, the line loss is lower, and the electric fee is less. |
|
Voltage drop (after selection) |
mid |
high |
low |
The conductor cable of the aluminum alloy achieves better skin effect, high transmission efficiency, and lower contact resistance cable performance through improved cable technology, and the line loss is lower, and the electric fee is less. |
|
Anti-corrosion performance |
general |
excellent |
better |
The inherent corrosion resistance of aluminum is due to the passivation of aluminum surfaces in contact with air, and immediately forms a thin, dense oxide layer that prevents oxidation, preventing further oxidation. |
|
Extended performance |
excellent |
poor |
better |
Better ductility through the boronation mechanism of rare earth aluminum alloy conductors |
|
Creep resistance |
excellent |
general |
better |
Aluminium alloys become excellent conductive alloy conductors by the action of rare earth elements |
|
Connector link stability |
