摘　　要：介绍了超导电缆结构,分析了超导电缆绞制过程中产生蛇形弯曲和外径不均匀的主要因素。非正规同向绞合的超导电缆是一种松散结构;绞制过程中,单根股线或子缆中存在的应力和放线张力不均匀是引起超导电缆产生蛇形弯曲的主要因素;绞合过程中各级子缆的排线和五级缆绞合时引起的扭转和变形以及分线的不均匀,是引起超导电缆蛇形弯曲的重要因素。通过合理配置各级缆绞合设备,控制绞制过程中收、放线张力,提升绞制设备的排线系统,改进不锈钢带绕包系统等措施,可有效防止超导电缆产生蛇形弯曲。The structure of the superconducting cable is introduced. The main factor which resulted in the serpentine bend and the nonuniformity in outer diameter when cabling are analyzed. The supereonductive cable twisted in the same but irregular direction appears a loose struction. During the twisting process, the main factor of serpentine bend caused by the tension and its inhomogeneity existed in the single or sub-stage strand（s） are presented. Another im- portant factor for twisting, deformation and uneven line caused by both winding displacement of every sub-stage and twisting of fifth-stage cable is also described. The serpentine bend can be avoided effectively by reasonable configura- tion of cable stranded equipment at all levels, adjusting the take-up and pay-off tension, upgrading the wire align sys- tern, and improving the wrapping system for the stainless steel.
