The paper Part I reported on the fabrication of high temperature capable electrical wires insulated with a new type of composite coatings comprising particulate ceramics and silicon-containing inorganic-organic nano-hybrids. This second paper studies the thermal, mechanical and dielectric properties of these composite insulated wires in accordance with relevant national standards. Techniques for materials characterization were also applied to provide information for better understanding the coatings' performance as wire insulation. Results showed that insulated wires have moderate dielectric strength comparable to ceramic insulation and excellent thermal stability, with insulation sustained for over 100 days at 500°C and prolonged period at 450°C under constant high temperature ageing and there is no obvious insulation degradation after thermal cycling for 20 times. The insulated wires demonstrated good mechanical properties, with interim flexibility allowing a minimal bending radius of 3 mm for 1.2 mm insulated wires. The resistance to abrasion and cutting through are also good enough to satisfy most practical applications.

用于电线热稳定绝缘的陶瓷/无机-有机纳米混合复合材料。第二部分：复合绝缘电线的特性

论文第一部分报道了用新型复合涂层绝缘的耐高温电线的制造，该复合涂层包括颗粒陶瓷和含硅无机-有机纳米混合物。第二篇论文根据相关国家标准研究了这些复合绝缘电线的热、机械和介电性能。还应用了材料表征技术来提供信息，以便更好地了解涂层作为电线绝缘层的性能。结果表明，绝缘电线具有与陶瓷绝缘相当的中等介电强度和优异的热稳定性，500℃保温100天以上，450℃长期恒温老化，20次热循环后保温性能无明显劣化。绝缘电线表现出良好的机械性能，具有临时柔韧性，允许 1.2 毫米绝缘电线的最小弯曲半径为 3 毫米。耐磨性和耐切割性也足以满足大多数实际应用。
