  湖北卖光缆多少钱?-欢迎咨询。

  船用通信电缆不能代替电力电缆,绝缘标准不同。

  通信电缆是传输电话、电报、传真文件、电视和广播节目、数据和其他电信号的电缆。它由一对以上的绝缘导线绞合而成。与架空明线相比,通信电缆具有通信容量大、传输稳定性高、保密性好、受自然条件和外界干扰影响小等优点。

  Power cables are cables used to transmit and distribute electric energy. Power cables are often used in urban underground power grids, power station lead-out lines, internal power supply in industrial and mining enterprises and underwater power transmission lines across rivers and seas. In power lines, the proportion of cables is gradually increasing. Power cable is a cable product used to transmit and distribute high-power electric energy in the trunk line of power system, including various voltage levels of 1-500KV and above and various insulated power cables. Strictly speaking, communication cable can't be used as power line, because the current carrying capacity of communication cable is very small, and the degree of withstand voltage and insulation is low, which is not enough to bear the large current and high voltage of power line, but it can be used as temporary wiring in the weak current field with small current and low voltage.

  室外光缆是完成光信号传输的通信线路。缆芯是由一定数量的光纤按一定方式组合而成,光纤外包护套,部分光纤还外包外护套。

  48芯光缆结构:

  在结构上,48芯光缆主要分为室外和室内两种结构类型。室外芯线有两种:中心束管式和层绞式。一般常用层绞式,因为层绞式含芯量大,防护性能比中心束管式好。(中心束管是光纤位于光缆中心,不填充膏体,用双钢丝加固的结构;层绞结构是一种光纤围绕中心增强体的结构形式。室内型以梁式结构为主(型号GJFJV)。
