The advantages of aluminum cables 1. cheap: the price of copper rod is 3.5 times aluminum pole, the proportion of copper is 3.3 times that of aluminum, aluminum cables so much more expensive than copper cable, suitable for low-funded project or temporary electricity. 2. Cable is very light: weight aluminum cable is 40% of the copper cables, construction, transportation costs are low. 3. Anti-oxidation, corrosion: aluminum reacts with oxygen in the air to form an oxide film quickly supply wire, to prevent further oxidation, so the aluminum wire is high voltage, large cross-section, a large span of overhead transmission Required materials. Although aluminum cable and inexpensive, but the copper wires in the power supply cable in the cable, in particular in the field of underground power cables, has outstanding advantages. Use copper cables underground power supply has low accident rate, corrosion resistance, high reliability, easy maintenance construction. It is also currently the main underground power cables using copper cables reason. Copper cables advantages 1. Low energy consumption: As the low resistivity of copper, compared to aluminum cables, the power loss of the low copper cable, which is obvious. This helps to improve power generation efficiency and protect the environment. 2. Antioxidant decoration wire, corrosion-resistant: stable performance copper cable connector will not accidents due to oxidation. Aluminum cable joint instability often increases the contact resistance due to oxidation of the wire factory, fever and accidents. Therefore, the accident rate is much greater than copper cable. 3. Construction of convenience: ① copper core flexibility, small bend radius allowed, so turning easy, easy to wear tube; ② copper core anti-fatigue, repeatedly bent not broken, so easy to wire; ③ high mechanical strength in copper core, can withstand greater mechanical tension, to the construction laying great convenience, but also to create the conditions for the mechanization of construction.
