Electric cables. Calculation of the current rating. Current rating equations (100% load factor) and calculation of losses-Sheath eddy current loss factors for two circuits in flat formation
电缆 电流额定值的计算 电流额定方程(100%负载系数)和损耗计算 扁平结构两回路的鞘层涡流损耗因子
Should be used for most sizes of aluminium-sheathed cables, but is not required for lead-sheathed cables unless they are unusually large.Cross References:IEC 287IEC 287-1-1
