铁道电缆
K24低烟无卤地铁信号电缆
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
电缆结构:
| 导体 | 实心铜导体，标称直径0.5/0.6/0.9 mm |
| 绝缘 | 实心聚乙烯绝缘 |
| 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 | 低烟无卤阻燃外护套 |
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。
