铁道电缆
EAPSP nx4x0.9/1.3/1.4
应用:
该电缆被用作铁道电缆可以直埋或管道敷设。
标准:
RENFE E.T. 03.365.051.6
电缆结构:
| 导体 | 柔软的实心退火铜导体，标称直径0.9/1.3/1.4 mm |
|---|---|
| 绝缘 | 聚乙烯绝缘 |
| 成缆单元 | 四根绝缘线扭绞为一个四线组 |
| 成缆方式 | 星绞四线组以螺旋层绞方式绞合为缆芯 |
| 缆芯绕包 | 塑料带搭接缠绕于缆芯外 |
| 防潮层 | 一层涂有聚合物的铝带(0.2mm厚)纵包，并与内护套粘接 |
| 内护套 | 聚乙烯 |
| 铠装 | 一层皱纹钢带纵包 |
| 外护套 | 聚乙烯 |
可选结构
填充型电缆：缆芯间隙填充石油膏为电缆提供纵向防渗能力。电缆内阻水带与屏蔽层间，屏蔽层与护套间的空隙均有防水填充物。
