Nanoparticles succeeded to enhance the dielectric properties of industrial insulation but the presence of voids inside the power cable insulation still leads to formation high electrical stress inside power cable insulation material and collapse. In this paper, the dielectric strength of new design nanocomposites has been deduced as experimental work done to clarify the benefit of filling nanoparticles with different patterns inside dielectrics. Also, it has been studied the effect of electrical stress distribution in presence of air, water and copper impurities with different shapes (cylinder, sphere and ellipse) inside insulation of single core. In simulation model, it has been used finite element method (FEM) for estimating the electrostatic field distribution in power cable insulation. It has been applied new strategies of nanotechnology techniques for designing innovative polyvinyl chloride insula-tion materials by using nanocomposites and multi-nanocomposites. Finally, this research succeeded to remedy different partial discharges (PD) patterns according to using certain types and concentrations of nanoparticles.

基于Valentine天线的辐射原理，设计出可发射峰值电压610 kV、频谱范围0.2~2 GHz高功率脉冲的超宽带天线。利用油作为绝缘介质过渡巴伦可使天线直接加载于50 Ω的同轴波导上；通过优化填充介质及天线拓扑结构提高了耐压能力及辐射特性。仿真结果表明，设计的天线具有低反射、宽频带、高增益和高耐压强度等优点。

介绍了一种电气绝缘柔软复合材料--DMD膜，通过对膜结构的分析，设计了一种串联等效电路模型对其进行分析。运用该模型，对DMD膜在浸渍前和浸渍后两种情况下的介电常数和介电强度进行了求解并给出计算公式。从公式可以看出: DMD膜的介电常数在浸渍前后有明显的变化，浸渍后的介电常数得到了显著的提高，并且变化率较小; 浸渍后DMD膜的介电强度高于未浸渍DMD膜的介电强度。当浸渍料介电常数愈大，聚酯材料上承受的电场强度愈大，浸渍料上承受的电场强度愈小，由于聚酯材料的耐压强度很高，所以整个传输线的介电强度得到提高。
