Abstract
一种铁路信号软电缆，包括缆芯及缆芯包带层、外护套，缆芯内的四线导体组的每根导线由多股镀锡铜丝及外包绝缘层构成，四线导体组的包带层外包覆由镀锡铜丝编织而成的屏蔽层，在缆芯包带层与外护套之间设置由铝镁合金丝编织的防护层，这种铁路信号软电缆屏蔽性能好，可实现同频信号同缆传输，柔软度好，易弯曲，在保证电缆强度的前提下减轻了电缆的重量，施工、维修较为方便。
Description
技术领域
本发明涉及一种通信电缆，尤其是铁路信号软电缆。
背景技术
现有铁路信号电缆的缆芯内的四线导体组的导线为单芯铜导线，柔软度不够；在四线导体组外不设屏蔽层，同频信号不能同缆传输；缆芯外的防护层采用双钢带绕包，导致电缆的重量和外径增大，并使电缆的弯曲性能下降，施工、维修作业不方便。
发明内容
为了克服现有铁路信号电缆的不足，本发明提供一种铁路信号软电缆，它具有屏蔽性能优、柔软度好、易弯曲，重量相对较轻，施工、维修方便等特点。
本发明提供的铁路信号软电缆包括缆芯及缆芯包带层、外护套，缆芯内设有数个外包包带层的四线导体组，四线导体组的每根导线由多股镀锡铜丝及外包绝缘层构成，四线导体组的包带层外包覆由镀锡铜丝编织而成的屏蔽层，在缆芯包带层与外护套之间设置由铝镁合金丝编织的防护层。
本发明的有益效果是：屏蔽性能好，具有良好的抗电磁干扰性能，并可实现同频信号同缆传输；柔软度好、易弯曲，在保证电缆强度的前提下减轻了电缆的重量，施工、维修较为方便。
附图说明
图1是本发明的横截面示意图。
在图1中，1.外包绝缘层的导线，2.四线导体组，3.四线导体组的包带层，4.屏蔽层，5.缆芯包带层，6.防护层，7.外护套，8.缆芯。
具体实施方式
在图1中，本发明的四线导体组(2)内的每根导线(1)采用多股镀锡铜丝绞合而成后外包绝缘层，，在四根外包绝缘层的导线(1)外用聚酯带包覆包带层(3)，再包覆用镀锡铜丝编织的屏蔽层(4)，即制成四线导体组(2)。将数个四线导体组(2)绞合制成缆芯(8)后包覆包带层(5)，再包覆用铝镁合金丝编织的防护层(6)，再在防护层(6)外包覆外护套(7)即制成本发明。
