ANSI/NEMA WC 51/ICEA P-54-440-2009（R2019）涵盖了安装在电缆槽中的600-15000伏固体介质电缆的载流量额定值。表中列出了单芯电缆、单芯电缆的三芯组件和包含整体护套的三芯电缆的载流量额定值。已将电缆结构的载流量和托盘应用通常遇到的操作条件制成表格。提供了调整列表值以更好地反映特定条件的修正系数。 其中包括考虑环境和工作温度、电缆结构、电缆槽盖和电缆负载多样化的调整。

ANSI/NEMA WC 51/ICEA P-54-440-2009 (R2019) covers the ampacity ratings for 600-15,000 volt solid dielectric cables installed in cable trays. Ampacity ratings are tabulated for single conductor cables, triplexed assemblies of single conductor cables, and three-conductor cables incorporating an overall jacket. Ampacities have been tabulated for the cable constructions and the operating conditions normally encountered for tray applications. Correction factors to adjust the tabulated values to better reflect specific conditions are provided. These include adjustments to account for ambient and operating temperatures, cable construction, tray covers, and diversification of the cable loading.
