2.2 电缆型式由系列代号、绝缘、护套材料代号、外护层和性能特征代号5个部分组成。
产品执行GB国家标准。
其中屏蔽型控制电缆，由于具有良好的评比性能得到电厂、电站的大量使用，电缆意义敷设在市内、电缆沟、管道、直埋、竖井等能承受较大机械拉里的固定场合。
(本规定仅用于电梯电气装置本身，不包括电梯的供电电源。
)条是由原规范第2.0.4条和第2.0.10条经删改合并而成。
为保证施工和维修的安全，增加了“220V及以上的端子应有明显标记”的规定。
考虑到TN—S系统接地型式的特点，故要求保护线端子也应加标记。
为与****协调，以利于识别，对保护线的颜色也做了规定。
本条关于中间接头的规定，只适用于线槽配线。
如采用热缩塑料管处理接头绝缘时，要特别注意加热的时间和距离，不能有烤焦现象，以保证接头的绝缘强度。
产品标准：YD/T产品型号：ZA-RVV（ZRRVVZRVVRRVVZ）通信电源用阻燃软电缆ZA-RVV22（ZRRVV22ZRVVR22RVVZ22）通信电源用阻燃钢带铠装软电缆本产品适用于架空、管道、室内电缆沟、地下直埋。
6KV及以上电缆接头：①安装电缆终端头时，必须剥除半导体电屏蔽层，操作时不得损伤绝缘，应避免刀痕凹凸不平的情况，必要时用砂纸磨平；屏蔽端部应平整，并要把石墨层（碳粒）清除干净。
②塑料绝缘电缆端头铜带屏蔽和钢铠必须良好接地，对短路也遵循这项原则，避免三相不平衡运行时钢铠端部产生感应电动势，甚至“打火”及燃烧护套等事故。

NT6000DCS因其综合的技术经济优势，已经并将继续在辅助车间控制方面发挥越来越大的作用。
在辅助车间应用广泛的PLC也并不会就此退出热工自动化的历史舞台，前所未有的竞争压力，将会促使PLC厂商在技术上向DCS标准靠拢，在价格上作出更大的努力。
DCS和PLC市场竞争的结果，将会使用户获得更大的利益。
DCS和PLC的控制处理能力一个PLC的控制器，往往能够处理几千个I/O点（最多可达8000多个I/O）。
缆芯包带：缆芯用聚脂薄膜带绕包。
屏蔽：用0．2mm厚的双面涂塑铝带轧纹(或不轧纹)纵包于缆芯包带外，搭接处粘合。
