The key of the former system was designed according to the fact of china in the project. The draught-tension control system adopted a primary-secondary Variable Voltage and Variable Frequency control system instead of speed governing system of direct current; The on-line measurement control technique of pendency of cable was discussed, and the equipment for this technique was developed; the equipment also can adjust itself to kinds of cables and the situation where parameter of capacitance change; the method is new, and it can be applied several other facets. In the project we adopted a PLC-DCS combined hybrid control method with the merits of flexible configuration. Accurate measurement, coordinated control, reliable performance and convenient maintenance, achieving a higher automation level of XLpe cable Manufacture. The content of the paper includes the present state of technique of XIpe cable Manufacture, includes the research on the draught-tension control system, focusing on scheme; includes the design of the on-line measurement control technique of pendency of cable. Keywords: XLpe; The Draught-Tension; Pendency of Cable 目 录 第1章 绪论 1 1.1选题背景和技术说明 1 1.2现代电缆行业的介绍 3 1.3交联电缆生产技术现状综述 4 1.4本设计的主要工作意义 5 第2章 交联电缆生产牵引张力控制系统 7 2.1张力控制系统概述 7 2.2 三种张力控制方案 7 2.3张力控制系统的方案确定 9 第3章 在线测控的悬垂控制器设计 11 3.1悬垂度测量的概述 11 3.2系统组成及测控原理 11 3.3系统硬件设计 11 第4章 电路设计 14 4.1中心控制电路 14 4.2发射信号输出电路 16 第5章 悬垂控制器参数说明 17 5.1基本参数说明 17 5.2模式选择 19 总 结 22 参考文献 23 附录：外文翻译 24 致 谢 45 第1章 绪论 1.1选题背景和技术说明 1.1.1选题背景 交联(XLPE-Cross
