随着我国科学技术的不断发展,通信电缆在我们的生活中已经密不可分。通信电缆由多根绝缘导线或导体组成。通信电缆也可以放在空中,也可以只买在管道和水下,也有很多种敷设方式。
通信电缆是传输频段的一种,广通信的容量大,不会受到外界干扰,但是不好修。它可以传送电话、电报、数据和图像。因此,通信电缆给生活带来了巨大的成果。
我们在电脑上玩手机或者看电视,都离不开通讯的信号。通信电缆的机械特性适合于纯铜导体的强度,其伸长率大于铜铝包铝导体,这意味着其酮体具有优异的机械性能。从通信电缆的设计角度来看。
Communication cables are suitable for urban and township telecommunication lines of local telecommunication networks, and also for special network lines connected to public networks. Mainly used for pipeline laying. The inner and outer surfaces of the cable core and the shielding layer are filled and poured with petroleum paste to prevent moisture from invading. Under the environmental conditions of 30~C and 60~C, the mechanical and electrical properties of the cable remain unchanged.
Structure of communication cable:
Conductor: annealed bare copper wire with a diameter of 0.32, 0.40, 0.50, 0.60, 0.70, 0.80 and 0.90 mm.
Insulation material: high-density polyethylene, medium-density polyethylene or polypropylene, and the color of the insulated wire conforms to the full chromatographic standard.
Insulated wire pair: two insulated wires with different colors are twisted in pairs according to different pitches, and the specified chromatographic combination is adopted.
缆芯结构:以25对为基本单位,25对以上的电缆按单元组合,每单元用规定色谱的扎带包裹,便于识别。100对或以上的电缆有1%的备用线对,但不超过6对。
缆芯胶带:缆芯用聚酯薄膜胶带包裹。
屏蔽:用0.2mm厚双面涂塑铝带纵向包在缆芯带外,然后在搭接处粘接。
护套:黑色低密度聚乙烯。可以提供双护套电缆。
