摘　　要：现有的高压大截面交联电缆蛇形敷设设计的有关规定有进行深入研究的余地。通过对设计规范和规定中有关高压大截面交联电缆蛇形敷设的内容进行解读,介绍了国外所用电缆敷设主参数的计算方法,对电动力、铝护套强度等影响电缆蛇形敷设的因素进行了比较。以工程实例进行了计算对比,并对电缆蛇形敷设设计与施工提出了建议。Currently, the snake laying design regulation of high voltage crosslinked cable exists space which need further research. Through explaining the content of the snake laying design criteria/regulation of high voltage crosslinked cable, the caculation method of major parameters in cable laying abroad is introduced. Some factors which can affect the snake laying of cables including electrodynamic force and aluminum sheath strength are compared. Calculation comparison of real cases in engineering is conducted. Some suggestions are proposed in respects of design and construction of cable＇s snake laying.
