K23 市内低烟无卤信号电缆
应用
该电缆用于地下铁网络中的远程控制及远程传输。该电缆可沿着最大值为1500V 的直流电气化市郊铁路线通过电缆沟，电缆桥架，或电缆钩支撑进行敷设。
标准
NF F 55-623
结构
- 导体：铜导体，标称直径0.6/0.8/1.0/1.2mm。
绝缘：实心聚乙烯。
成缆单元：四根绝缘线绞合成一个四线组。对于1 对及4 对的电缆，导体以双绞线形式绞合。
成缆方式：四线组以同心式螺旋层绞或单元形式绞合成缆芯。
缆芯绕包：塑料带搭接缠绕。
防潮层：一层包覆有聚乙烯聚合物涂层的铝带纵向搭接缠绕，并与内护套粘接。
内护套：低烟无卤阻燃材料。
铠装：双层钢带螺旋缠绕。
外护套：低烟无卤阻燃材料。
