摘要/Abstract

摘要： 铝芯电缆相比铜芯电缆的购置费用低，但其技术性能相对较差。从长期经济性角度选择铜或铝芯电缆，考虑资金的时间价值，建立包括购置、敷设、电能损耗、运行维护、故障损失和退役成本的电缆全生命周期成本（LCC）计算模型，通过对铜、铝芯电缆LCC的计算和比较，以LCC最小作为铜、铝芯电缆间选择标准。以广州城区某电缆线路作为案例进行计算分析，结果表明铝芯电缆相比铜芯电缆购置成本优势较大，但敷设成本和后期运行成本具有劣势，总LCC更大，铜芯电缆为最优方案，证明LCC方法的可行性。

Abstract: Compared to copper power cable, purchase cost of aluminum power cable is much smaller, but technical performances are weaker in many aspects. In order to select between copper and aluminum power cable from long-term economic perspective, cable life cycle cost (LCC) model is established with consideration of time value of money. The model includes cost of purchase, installation, electricity loss, maintenance, failure loss and decommission. After calculation and comparison of LCC of two different cables, selection is made based on total LCC cost. Case study of cable line in Guangzhou urban area is performed. The results show that although purchase costs of aluminum cable are less than that of copper cable, the installation and operation costs of aluminum cable are much higher. Copper cable is better choice between two materials.

Key words: life cycle cost, long-term economic, copper power cable, aluminum power cable, selection method
