本文简述了直埋配线电缆的发展慨况,介绍了我所设计的聚乙烯全填充电缆的结构、工艺和电气性能。并通过渗水试验、气压试验和现场敷没试验证明了该电缆具有稳定的电性能和良好的纵向防水性,特别适宜于部队直埋使用。 This article briefly describes the development of direct buried cables and presents the structure, process and electrical properties of the fully filled polyethylene cables designed by me. Through water seepage test, air pressure test and field unwrapping test, it has been proved that the cable has stable electrical performance and good longitudinal waterproofness. It is especially suitable for direct burial of troops.
