新型农用直埋电力电缆线路综合分析与评价

General Analysis and Evaluation of a New Type of Directly-Buried Rural Cables

介绍了新型农用直埋电力电缆系列产品与JB/T 2171标准界定产品的结构差异及特征。通过对新型农用直埋电力电缆使用特性和线路实际运行的调研及综合分析,说明新型农用直埋电力电缆线路较适合农网低压系统应用。进而比较不同线路方案的造价,并对新型农用直埋电力电缆产品制造工艺及市场前景进行评估,认为农网低压线路选用新型农用直埋电力电缆可以实现造价低、线损小、安全、可靠的目的,其已经具备推广和实际应用的条件及市场前景。

This paper presents the differences between a new type of directly-buried rural cables and those specified by JB/ T 2171. Investigation on the performance and practical operation of the new cables shows that the new cables are more suitable for rural LV system. Production costs were compared for different types of cables. Evaluation was made for the process and market of the new cables, As a result, we hold that the use of the new cables in rural LV system has the advantages of low cost, low loss, safety and reliability and that the new cables can be popularized and has good market prospects.
