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

excellent

general

excellent

By providing the same conductor material, the coefficient of thermal expansion and contraction of copper-aluminum transition terminals tends to be uniform
