标准摘要
[中文适用范围]： IEC 60287 的这一部分规定了选择电缆尺寸的方法，考虑到电缆预期使用寿命期间的初始投资和未来能量损失成本。本标准未包含诸如强制冷却系统中的维护@能量损失和一天中的能源成本等问题。附录 A 给出了将该方法应用于假设供应系统的两个例子。 [外文原描述]： IEC 60287-3-2:2012 sets out a method for the selection of a cable size taking into account the initial investments and the future costs of energy losses during the anticipated operational life of the cable. Matters such as maintenance, energy losses in forced cooling systems and time of day energy costs have not been included in this standard. Two examples of the application of the method to hypothetical supply systems are given in Annex A.
