【技术实现步骤摘要】
本专利技术涉及一种复合电缆,具体地说是涉及一种能同时传输光信号和电信号的复合电缆。
技术介绍
目前,用于短距离传输使用的光缆、电缆通常是单独敷设的,因此占用城市管道的资源比较多,建设成本高。因光缆本身应具有良好的防潮、防水、抗拉性能,同时加上通信电缆线对,使光信号和电信号同时传输而互不受影响,要求复合光缆有好的电磁屏蔽性能、较高的抗拉、抗侧压以及良好的绝缘和耐电压等多项性能。现有技术的光缆不能传输电信号;电缆不能传输光信号,如需同时传输光电两种信号,则必须同时敷设光缆和电缆才能实现,使城市管道资源浪费较多,建设成本增高,也造成了管道的重复占用。
技术实现思路
针对上述现有技术的不足,本专利技术的目的是提供一种能同时传输光信号和电信号的复合电缆,该电缆可同时传输光电两种信号,以解决光缆不能传输电信号及电缆不能传输光信号之不足。为了实现上述目的,本专利技术采用的技术方案是:一种能同时传输光信号和电信号的复合电缆,包括缆芯、电线单元和外护套,所述缆芯由光纤、防水纤膏和束管组成,在束管内设有多束光纤,在束管与光纤之间设有防水纤膏,在缆芯外设有多个电线单元,在电线单元外包覆有阻燃填充层,在阻燃内护套层外包覆有外护套。优选的,所述电线单元外表面设有绕包成型的聚酯带。进一步,所述电线单元内的铜线具有高导电性镀层。采用本技术方案的专利技术,其优点是:本专利技术的复合电缆,可同时传输光信号和电信号,解决了光缆不能传输电信号及电缆不能传输光信号之不足。本专利技术结构简单,且光传输与电传输互不干扰,可广泛应用于建筑物内的光电缆敷设,其集光纤、电缆于一体,可以解决宽带接入、设备用电 ...
