近年来，在开发新型介电材料方面已经进行了大量的工作，这些材料提供了各种性能的改进。关于如何通过更智能的电介质设计来改善特定性能的问题经常被问及。然而，从网络运营商的角度来看，感兴趣的不仅仅是介电设计，而是成品在网络中的表现。本文旨在说明电缆系统的介电性能的进步可以使电缆性能得到哪些可量化的改善。该分析是在电缆电路的额定工作电流和每单位传输功率的相关损耗的背景下进行的。结果分析表明，电缆的操作性能的最大改善可以从增加介电导热系数，即使它是在其他性能略有下降的代价。
In recent years, a significant volume of work has been undertaken on the development of novel dielectric materials which offer improvements in a variety of properties. Questions are frequently asked as to how particular properties can be improved by more intelligent dielectric design. However from the point of view of the network operator it is not just the dielectric design which is of interest - rather, how the finished product performs in the network. This paper seeks to demonstrate what quantifiable improvements in cable performance could be gained through advances in the dielectric properties of cable systems. The analysis is set in the context of the operational current rating of the cable circuit and the associated losses per unit of power transferred. Analysis of the results shows that the greatest improvement in cable operational performance can be made from increasing the dielectric thermal conductivity, even if it comes at the expense of a slight decrease in other properties.
