Introduction to Aluminium Core Cables_Disadvantages & Performance
1. Less conductive than copper wire
Aluminium-core wires are less conductive than copper wires, resulting in the need to use thicker aluminium-core wires when building circuits in order to achieve the same transmission effect as copper wires. This, in turn, will lead to an increase in the size of the wire, the installation is more difficult, the installation cost will also increase.
2. Susceptible to external damage
Aluminium core wire flexibility is relatively poor, easy because of the role of external forces caused by deformation, damage to the wire, affecting its normal conductive effect. In outdoor use need to pay extra attention, because the aluminium core wire is hard, easy to break.
3. Easy to age
Compared with copper wire, aluminium core wire aging faster, so after a long time of use, aluminium core wire may become very fragile, very easy to break. When the aluminium core wire is aging, it needs to be replaced in time, otherwise there may be a short circuit, fire and other risks.
1. Electrical conductivity
In order to reduce the energy loss and voltage drop in the cable conductor, the conductor of the power cable is generally made of copper and aluminium with high conductivity. Under the premise of the same cross-sectional area of the conductor, the conductivity of copper-core power cables is higher than that of aluminium-core power cables.
2. Processing performance
Copper ductility is good, strong mechanical properties, so in the mono filament compression, even if the degree of deformation is very large, copper core power cable conductor will not break. However, the mechanical properties of aluminium is poor. When the conductor is stranded, if the compression coefficient is high, the conductor will appear burrs, broken wire, or even broken wire.
3. Economic performance
In the case of the same current-carrying capacity, the cross-sectional area of aluminium-core cables is about 1.5 times that of copper-core cables, and the corresponding cost of line protection and civil engineering costs will also increase. Therefore, as a permanent power distribution, taking into account the operational safety aspects, in the case of capital conditions allow, the more recommended use of copper-core power cables.
