What are the advantages of aluminum conductor cables?

Aluminum cable is a cable with a core made of aluminum and an outer shell of insulating material. Its main advantages are light weight, easy installation, and the price is more favorable than copper core cables. Aluminum core cables are widely used in power transmission, lighting, manufacturing, aerospace and other fields.

Aluminum core cable specifications include BLV, YJLV, YJLV22, VLV, and VLV22. Aluminum core cables generally refer to copper-clad aluminum cable, which refer to wires and cables in which aluminum core wires replace copper as the main body of the cable and are covered with a certain proportion of copper layers.

Advantages of aluminum cables:

1. Oxidation resistance and corrosion resistance. Aluminum reacts quickly with oxygen in the air to form an oxide film, which prevents further oxidation. Therefore, aluminum conductors are an essential material for high-voltage, large-section, and large-span overhead power transmission. Although aluminum cables are relatively cheap, copper core cables have outstanding advantages in cable power supply, especially in the field of underground cable power supply.

2. The cable is very light. The weight of aluminum core cable is 40% of copper core cable, and the construction and transportation costs are low.

3. Cheap price. The specific gravity of copper is 3.3 times that of aluminum, so aluminum core cables are much cheaper than copper core cables and are suitable for low-demand projects or temporary power consumption.

Performance of aluminum cables:

1. Conductive properties

In order to reduce energy loss and voltage drop in cable conductors, the conductors of power cables are generally made of copper and aluminum with high conductivity. Under the premise of the same conductor cross-sectional area, the conductivity of copper core power cables is higher than that of aluminum core power cables.

2. Processing performance

Copper has good ductility and strong mechanical properties, so when the single wire is compressed, the conductor of the copper core power cable will not break even if the degree of deformation is large. However, aluminum has poor mechanical properties. When the wire is twisted, if the compression coefficient is high, burrs, broken wires, or even broken wires will appear in the wire.

3. Economic performance

Under the same carrying capacity, the cross-sectional area of aluminum core cables is about 1.5 times that of copper core cables, and the corresponding line protection costs and civil construction costs will also increase. Therefore, as permanent power distribution, taking into account operational safety, it is recommended to use copper core power cables if financial conditions permit.
