ETAP 电缆热分析模块可以详细模拟单芯和多芯电缆的物理结构。可以根据实际电缆结构单独定义各种电缆热层和金属层类型以及相应的尺寸。
利用先进的基于网络的绘图工具，可以根据工程师的要求生成和定制电缆瞬态温度图。
增强的交互界面可帮助工程师快速、直观地设计和绘制滚道。通过捕捉指南，无需输入坐标，只需拖动即可精确定位导管和管道。自动尺寸标记可加快管道布局的生成，无需额外的编辑和注释。
电缆容量/载流量计算和电缆尺寸计算基于 NEC 认可的 Neher-McGrath 方法和 IEC 60287 标准，用于稳态温度计算。瞬态温度计算基于动态热电路模型。所有这些计算都可以处理多管道系统，并考虑相邻电缆和外部热源产生的热量的影响。
Learn how to determine optimal cable sizes, physical attributes, and maximum ampacity using ETAP’s Underground Raceway System module, ensuring that cables in duct banks or directly buried are operating within their maximum potential capacity. In addition, transient temperature analysis computes temperature profiles for cable currents, reducing the risk of damage to cable systems under emergency conditions. All cable steady-state temperature calculations are based on the Neher-McGrath Method and the IEC 60287 Standard.
Learn how to save design time using the Raceway Rulebook to auto-layout cables within duct banks. Find out how to determine the optimal cable sizes, physical attributes, and maximum derated ampacity using Neher-McGrath method and IEC 287 standard.
Proper sizing and current derating ensures that cables operate to their maximum potential while providing secure and reliable operation. Learn about design and application requirements to properly size and analyze cable systems based on IEEE and North American cable standards and guidelines: IEEE 399, ICEA P-54-440, NEC NFPA 70
Proper sizing and current de-rating ensures that cables operate to their maximum potential while providing secure and reliable operation. This webinar covers cable sizing, current carrying capacity and electrical shock protection based on IEC and British standards
This Cable Thermal Analysis webinar explains how to design cable systems to operate to their maximum potential while providing a secure and reliable operation.
Underground Raceway Systems helps engineers to design cable systems to operate to their maximum potential while providing secure and reliable operation.
The magnetic field exposure analysis tool uses balanced & unbalanced load-flow currents and angles to determine the location of the worst-case magnetic field exposure due to conductors in underground raceways.
