K24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 的直流电气化铁路线通过电缆沟，电缆桥架，或电缆钩支撑进行敷设。
标准
AFNOR NF F 55-624
结构
- 导体：实心铜导体，标称直径0.5/0.6/0.9 mm。
绝缘：聚乙烯。
成缆单元：每两根绝缘线绞合成为一对。
成缆方式：对于少于15 对的电缆，线对以螺旋层绞方式绞合成为缆芯。对于21 对到112 对之间的电缆，线对以层绞或线束方式绞合成为缆芯。
缆芯绕包：一条或多条长的合成带缠绕于缆芯外。
屏蔽层：铝/ 聚酯带屏蔽。
排流线：镀锡铜排流线，标称直径0.5mm。
护套：阻燃低烟无卤。 - 可选结构
铠装电缆：对于铠装电缆，在屏蔽层外搭接绕包一层或多层包带作为衬垫层，衬垫层外为双重钢带铠装和无卤防火外护套。
